Best European PDF Tools

#1 Smallpdf

Zurich, Switzerland Founded 2013 Free with daily limits / Pro from about €9 per month Free tier

Best for: Everyday PDF work on documents that are sensitive but not classified

• Operating company. Smallpdf AG
• Jurisdiction. Switzerland (adequacy decision, outside the EEA)
• Where the data sits. Switzerland
• Independent checks. ISO 27001, GDPR
• Source code. Closed source
• Replaces. Adobe Acrobat, iLovePDF

Smallpdf covers the everyday PDF surface with 21 tools — compress, convert, merge, split, OCR, e-sign and edit — in an interface that requires no explanation, which is most of what a business actually needs from this category.

Its privacy position is unusually specific, and specificity is what makes it useful. Files are deleted within the hour rather than "periodically", hosting is in Switzerland under Swiss data protection with an EU adequacy decision, and the company holds ISO 27001 certification — an audited security standard rather than a self-declaration. For documents that are confidential but not classified, that combination is a reasonable place to land.

Desktop and mobile applications extend it beyond the browser, and Google Drive and Dropbox integration handle documents that already live in the cloud. Smallpdf AG has operated from Zurich since 2013. The limits: the free tier is restrictive with daily caps, in-PDF text editing is limited compared with Sejda, and there is no self-hosted or offline-only mode — so genuinely confidential material belongs on Stirling PDF or PDF24 desktop instead. Pro from about €9 per month.

Standout feature. Deleted within the hour, ISO 27001, hosted in Switzerland — three specifics where most services offer a paragraph.

#2 iLovePDF

Barcelona, Spain Founded 2010 Free with limits / Premium from about €4 per month / API priced separately Free tier

Best for: Regular work across many files at once, and developers needing a PDF API

• Operating company. iLovePDF S.L.
• Jurisdiction. EU (Spain)
• Where the data sits. EU
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Adobe Acrobat, Smallpdf, PDF24

iLovePDF is built around volume. Batch processing across its 25-plus tools handles a folder of documents in one operation rather than one file at a time, which is the difference between a five-minute task and an afternoon for anyone doing this regularly — compressing a set of scans, converting a batch of reports, watermarking a month of invoices.

The REST API with client libraries extends the same capability into software, so a document workflow can call compression, conversion or OCR programmatically instead of a person visiting a website. For a business automating invoice or contract handling, that is the feature that matters, and it is priced separately from the consumer plans.

A desktop application processes files locally rather than uploading them, and mobile apps include scanning with OCR so a photographed document becomes searchable text. iLovePDF S.L. has operated from Barcelona since 2010 with EU data processing under GDPR. The free tier is generous but carries ads, the web version uploads files, and in-PDF text editing is basic. Premium from about €4 per month.

Standout feature. Batch processing plus a real API — the two things that turn PDF work from a task into a pipeline.

#3 Stirling PDF

United Kingdom Founded 2023 Free and open source / commercial Enterprise tier available Free, self-hosted

Best for: Organisations that cannot upload documents to a third-party service

• Operating company. Stirling Tools
• Jurisdiction. Runs wherever you deploy it
• Where the data sits. Your own server
• Independent checks. GDPR — you remain sole controller
• Source code. Open source
• Replaces. Adobe Acrobat, Smallpdf, iLovePDF

Stirling PDF gives you the capability of a commercial PDF suite with the upload removed. More than 50 operations — OCR, splitting and merging, conversion, form filling, signing and redaction — run entirely on your own server, with no telemetry of any kind and you remaining the sole data controller. For a law firm, a clinic or a public body, that is the difference between having PDF tooling and having a policy that forbids it.

True redaction deserves separate mention. Drawing a black rectangle over text in many tools leaves the text underneath, recoverable by copy-paste or extraction — a failure that has produced real disclosures of information people believed removed. Stirling PDF removes the content, which is what redaction is supposed to mean.

Pipeline automation handles bulk work: a folder of documents runs through a defined sequence of operations rather than one file at a time through a browser, which is what makes it viable for a records team rather than only an individual. The core is MIT-licensed and free. Stirling Tools has run it since 2023. Costs: someone has to deploy and update it, the interface is functional rather than polished, and some features sit in the commercial Enterprise tier.

Standout feature. Redaction that actually removes the text — not a black rectangle that copy-paste defeats.

#4 OnlyOffice

Riga, Latvia Free self-hosted / cloud from €4 per user per month Free self-hosted

Best for: Teams needing Microsoft Office compatibility with European data control

• Operating company. Ascensio System SIA
• Jurisdiction. EU (Latvia)
• Where the data sits. EU, or self-hosted
• Independent checks. GDPR
• Source code. Open source
• Replaces. Microsoft 365, Google Docs

OnlyOffice sits in this category because PDF handling is part of a full office suite rather than the product itself. Documents, spreadsheets and presentations with real-time collaboration replace Microsoft 365 or Google Docs, and its Microsoft Office format compatibility is the strongest of the open-source suites — which matters because the practical test of any Office alternative is whether a .docx comes back looking the same.

Deployment is where it earns its European argument. Self-hosting is fully supported, so documents live on infrastructure you control, and the cloud version runs in the EU. Ascensio System SIA is based in Riga, so an EU member state governs the vendor as well as the hosting.

It is open source with security features including document protection, and the cloud runs from €4 per user per month while self-hosting is free. For PDF work specifically it covers viewing, conversion and form filling rather than the deep manipulation Stirling PDF or Sejda offer — so a team may well run OnlyOffice for documents and something else for PDF-specific tasks.

Standout feature. A .docx that comes back looking the same — the only test an Office alternative actually has to pass.

#5 PDF24

Berlin, Germany Founded 2009 Completely free, web and desktop Free, no account required

Best for: Anyone wanting full PDF capability at no cost, especially offline

• Operating company. Geek Software GmbH
• Jurisdiction. EU (Germany)
• Where the data sits. Germany (online) or entirely local (desktop)
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Adobe Acrobat, Smallpdf, iLovePDF

PDF24 is completely free with no page limits, no account and no registration, across more than 30 tools on both web and desktop. In a category where free tiers exist to be outgrown, that is worth stating plainly before anything else.

The Windows desktop application is the reason it belongs in the serious part of this list rather than the convenient part.

It works entirely offline, so a confidential document is processed on the machine it already sits on and never becomes a transfer — which puts it alongside Stirling PDF as an answer for material that cannot be uploaded, without needing a server to run it. It includes a virtual PDF printer, so anything printable becomes a PDF from any application.

The web tools cover compression, conversion, merging, splitting, signing and OCR with German hosting by Geek Software GmbH in Berlin, and requiring no account means there is nothing linking a document to a person. The honest costs: the desktop app is Windows only, the interface is dated and cluttered in a way that makes it look less trustworthy than it is, and the website is ad-supported.

Standout feature. A free desktop app that works with the network off — confidential documents processed without ever becoming a transfer.

#6 Nutrient

Vienna, Austria Founded 2011 Custom licensing by platform and deployment Contact sales

Best for: Software vendors embedding PDF capability into their own products

• Operating company. Nutrient (formerly PSPDFKit GmbH)
• Jurisdiction. EU (Austria)
• Where the data sits. Runs in your application; on-premise processing available
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Adobe PDF SDKs, Foxit SDK

Nutrient, formerly PSPDFKit, is not a tool for editing documents — it is what software companies license so their own products can handle documents. SDKs for web, iOS, Android and server cover PDF viewing, editing, annotation, forms, digital signatures, redaction, OCR and conversion, which is the alternative to spending years building PDF handling in-house against a specification far harder than it appears.

On-premise and containerised deployment is the capability that makes it viable for regulated markets: document processing can run inside the customer's own infrastructure rather than calling out to a service, so a vendor selling to a hospital or a bank can meet requirements the customer will not waive.

True redaction and digital signatures are included rather than reserved, which matters when the vendor's customers are the ones who need them. Nutrient has operated from Vienna since 2011, giving an EU supply chain for a component that ends up embedded inside a product. Licensing is custom and quoted per platform and deployment, it is a proprietary single-vendor dependency, and it is entirely irrelevant unless you are shipping software.

Standout feature. On-premise SDKs: your customers' documents can be processed inside their own walls, which is what wins regulated deals.

#7 Sejda

Netherlands Founded 2010 Free with daily limits / web from about $7.50 per month / desktop licence available Free tier

Best for: Editing text inside existing PDFs without buying Acrobat

• Operating company. Sejda BV
• Jurisdiction. EU (Netherlands)
• Where the data sits. EU; desktop version processes locally
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Adobe Acrobat, Smallpdf, iLovePDF

Sejda does the thing most PDF editors only claim to do. Genuine text editing inside an existing PDF means changing a word in a paragraph and having the paragraph behave like a paragraph, rather than layering a text box over the original — which is fine for filling a form and useless for fixing a typo in a contract. That capability is why most people start pricing Acrobat, and it is the reason to look here first.

Around it sit forms, merge and split, OCR, compression, signing and redaction, so it works as a general PDF tool rather than only an editor. A desktop version processes files locally for documents that should not be uploaded at all.

Uploaded files are deleted after two hours, and Sejda BV is based in the Netherlands, so processing is intra-EEA under GDPR rather than under an adequacy decision. The free tier carries daily limits on tasks and file sizes, web plans start from about $7.50 per month, and a desktop licence is available separately. It is less broad than iLovePDF on batch work and has no API for automation.

Standout feature. Real text editing inside the PDF — the one capability that sends people to Acrobat, available here for $7.50 a month.

#8 PDFsam

Bibbiano, Italy Founded 2006 PDFsam Basic free and open source; PDFsam Visual and Enhanced sold as an annual subscription or a one-time perpetual licence, price shown at checkout 14-day free trial (Visual/Enhanced)

Best for: Free, offline merging and splitting of PDFs

• Operating company. Sober Lemur S.r.l.
• Jurisdiction. EU (Italy)
• Source code. Open source
• Replaces. Adobe Acrobat, online merge/split tools

PDFsam Basic has been developed since 2006 and is released under the AGPL-3.0 licence, which makes it the free option in this category rather than a review copy with a nag screen.

It merges, splits, rotates, extracts and mixes PDF pages, plus converts images to PDF and interleaves scanned sheets, all running locally on Windows, macOS or Linux with no file ever leaving the machine. For a one-off merge or a recurring split job, it does exactly what it says and nothing more.

PDFsam Visual adds a thumbnail-based interface for composing, reordering and cropping pages by clicking rather than scripting page ranges, and PDFsam Enhanced adds further editing tools; both are commercial products sold as an annual subscription or a one-time perpetual licence, with a 14-day trial. That puts PDFsam in an unusual position for this category: the same publisher offers both a genuinely free, permanent tool and a paid upgrade path, rather than a free tier designed to expire.

Sober Lemur S.r.l. is based in Bibbiano, near Reggio Emilia, Italy. What PDFsam does not do is also worth stating plainly: no OCR, no e-signing, no cloud sync and no API, so it sits well below Stirling PDF's 50-plus operations or iLovePDF's batch API in scope. It is a narrow tool that does a few operations for free, forever, which is a different promise than the all-in-one services above it.

Standout feature. A free, open-source core with no expiry date or file limits — rare in a category full of capped free tiers.

#9 PDF-XChange Editor

Bolney, West Sussex, United Kingdom Founded 1997 PDF-XChange Editor from about €56 per user, PDF-XChange Editor Plus from about €71 per user — one-time perpetual licences including a year of maintenance Free trial (~70% of features unlocked)

Best for: A one-time licence instead of a subscription

• Operating company. Tracker Software Products Ltd (PDF-XChange Co Ltd)
• Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
• Source code. Closed source
• Replaces. Adobe Acrobat, Foxit PDF Editor

PDF-XChange Editor is sold the way desktop software used to be sold: pay once, own the licence, keep using the version you bought.

Editor starts at about €56 and Editor Plus at about €71 per user, both perpetual and both including a year of maintenance — against a category where most competitors ask for a recurring plan or a per-document upload limit. Over 400 features cover annotation, page editing, format conversion, digital signatures and cloud storage integration with OneDrive, Dropbox and Google Drive.

Editor Plus adds a more accurate OCR engine, fillable form creation, document comparison and dynamic JavaScript-driven stamps, which puts real editing depth alongside Sejda rather than the lighter conversion tools in this category.

Everything runs locally on the machine it's installed on — nothing is uploaded to process a file — so it sits with Stirling PDF and PDF24's desktop app as an answer for documents that should not leave the building, but as a licensed Windows application rather than a self-hosted server or a free printer driver.

Tracker Software Products Ltd began trading as PDF-XChange in the UK in 1997 and now operates as a subsidiary of PDF-XChange Co Ltd, registered in England, with offices also in Canada, Bulgaria and Ukraine.

The trial unlocks roughly 70% of features rather than the full product, and it is Windows-only with no native macOS or Linux build, which rules it out for a mixed-platform office. For a Windows shop that wants to own its PDF editor outright, it is a straightforward buy.

Standout feature. A perpetual licence from about €56 — pay once for a desktop editor in a category most vendors sell as a subscription.

#10 pdfToolbox

Berlin, Germany Founded 1995 14-day free trial

Best for: Print and prepress teams checking PDFs before press

• Operating company. callas software GmbH
• Jurisdiction. EU (Germany)
• Source code. Closed source
• Replaces. Enfocus PitStop, Adobe Acrobat Preflight

pdfToolbox exists for a problem none of the other tools in this category solve: a PDF that looks fine on screen but fails in a printing press or an automated production line because of a missing bleed, an untagged font or the wrong colour space. Preflight profiles check files against PDF/X, PDF/A, PDF/UA and Ghent Workgroup standards, and can fix what they find automatically rather than only flagging it, using JavaScript for logic that goes beyond a checkbox list.

Beyond checking, pdfToolbox converts between image formats including PNG, TIFF and PSD, adds production marks, cut contours and bleed, manages ICC and DeviceLink colour profiles, and handles spot-colour separations — production steps a print shop currently does by hand or through a separate tool such as Enfocus PitStop.

Hot folders and customisable reports in PDF, XML or JSON let a shop wire pdfToolbox into an existing automated production line rather than running every file through a person one at a time.

callas software GmbH has worked on PDF since 1995 and is based in Berlin, with HRB 59615 at the Amtsgericht Charlottenburg.

Pricing is not published; a 14-day trial is available and a quote follows a conversation with sales, which is normal for production software sold to a shop rather than a consumer. This is not a tool for editing a contract or signing an invoice — for that, Smallpdf or Sejda are the better fit — but for a business whose output has to survive a printing press, nothing else in this category checks for it.

Standout feature. The only tool here that checks a PDF against PDF/X, PDF/A and PDF/UA standards before it reaches a printing press.

#11 PDFCreator

Hamburg, Germany Free edition free; Professional from about $22-29 per workstation per year (volume discounts from 10 units), excl. VAT; Server and Terminal Server editions quoted separately 30-day free trial (Professional)

Best for: Turning any Windows print job into a PDF

• Operating company. Avanquest pdfforge GmbH
• Jurisdiction. EU (Germany)
• Source code. Open source
• Replaces. Adobe Acrobat, doPDF, CutePDF

PDFCreator installs as a virtual printer, so any Windows application that can print can produce a PDF instead — the same trick doPDF and Bullzip use, but built out into a genuine automation platform rather than stopping at conversion. The Free edition, released under the AGPL, covers PDF creation, merging and page rearranging with no cost and no time limit, which is the same territory as doPDF but with a heavier, more configurable interface around it.

Where PDFCreator earns its place above a simple printer driver is Professional and the server editions: customisable profiles that auto-save, FTP, email or run a custom C# script after every conversion, 256-bit encryption, digital signatures, PDF/A archiving and Group Policy management for rolling it out across a company.

A Terminal Server edition adds centralised management for Citrix and RDS environments, and a Server edition handles high-volume automated conversion with multiple simultaneous threads — the kind of deployment an IT department manages rather than a single desk.

Avanquest pdfforge GmbH is registered in Hamburg (HRB 185235) and trades under the pdfforge and PDFCreator names as part of the Avanquest software group.

Professional pricing runs per workstation per year through an online calculator rather than a published list price, with volume discounts starting at 10 licences; the Free edition carries no such cost but also none of the automation. It is Windows-only, and next to Stirling PDF's 50-plus self-hosted operations, PDFCreator does one thing — printing to PDF — very thoroughly rather than covering the rest of the category.

Standout feature. An AGPL-licensed virtual printer that scales from a free personal tool to Terminal Server automation for an entire company.

#12 doPDF

Cluj-Napoca, Romania Founded 1999 Free, no time limit; doPDF Premium a one-time $14.99 payment removes ads and adds password protection Free version has no time limit

Best for: A free, no-frills PDF printer for occasional use

• Operating company. S.C. Softland S.R.L.
• Jurisdiction. EU (Romania)
• Source code. Closed source
• Replaces. Adobe Acrobat, CutePDF, Bullzip PDF Printer

doPDF does one thing: it installs as a printer so that any Windows application can "print" a PDF instead of paper, converting hidden hyperlinks and bookmarks from Office documents in the process. It has been free since S.C. Softland S.R.L. released it in 1999, with no time limit, no page count restriction and no forced upgrade — a rarer combination in this category than the free tiers of Smallpdf or iLovePDF, which cap usage by design.

The honest comparison is with PDFCreator, the other virtual-printer tool added to this category alongside it: PDFCreator wraps the same trick in automation profiles, scripting and a Terminal Server edition for IT departments, while doPDF stays deliberately simple — install it, print to it, done. That makes doPDF the better fit for a single user who wants a PDF printer and nothing else, and PDFCreator the better fit for a business that wants to automate the same job at scale.

S.C. Softland S.R.L. is registered in Cluj-Napoca, Romania (J12/1244/1999), and also publishes novaPDF for buyers who need a print server. doPDF Premium removes the installer's ads and adds password protection for a one-time $14.99, which is priced in dollars rather than euros on the vendor's own order page. There is no OCR, no merging, no editing and no mobile app — for anything beyond turning a document into a PDF, look elsewhere in this category.

Standout feature. A PDF printer that has stayed free with no time limit since 1999 — no account, no cap, no catch.

#13 BFO PDF Library

London, United Kingdom Founded 1998 Free trial (watermarked output); 30-day full licence key on request

Best for: Java developers embedding PDF handling in enterprise software

• Operating company. Kensington Software Management Ltd (trading as BFO)
• Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
• Source code. Closed source
• Replaces. iText, Apache PDFBox, Aspose.PDF

The BFO PDF Library is a pure Java component for building, editing, signing and rendering PDF documents inside somebody else's software, which puts it in the same market as Nutrient rather than alongside the split-and-merge utilities in this category.

It handles document creation and editing, encryption and digital signatures, embedded images and barcodes, full AcroForm support, and typography fast enough to process over a thousand words a second with kerning and ligatures intact — the detail work a bank's statement generator or an insurer's policy engine actually needs.

It runs on any Java 1.4+ platform with no native-code dependencies, which matters for a server environment where installing a native library is its own approval process, and the company states that half of the world's 30 largest banks are among its users, across more than 50 countries.

Where Nutrient covers web, iOS, Android and server with a broader platform reach, BFO is narrower and Java-only — precisely the trade-off a Java-only shop is usually happy to make for a smaller, more predictable dependency.

Kensington Software Management Ltd, trading as BFO, is based in London and has sold the library since 1998.

Pricing is not published: licensing runs per server, as an OEM/embedded fee, or as an unlimited annual licence, all quoted on request, with a watermarked trial download and a 30-day full licence key available while payment is processed. It is entirely irrelevant to anyone editing a document by hand — Smallpdf or Sejda are that tool — and relevant only to a team writing Java code that needs to produce or read PDFs reliably.

Standout feature. A Java-only PDF library trusted by half the world's top 30 banks — narrow by design, and priced for that market.
