Detailed Review
Nyxiontech PDF Tools takes a different route from most of the tools on this page. Instead of uploading a document to a server, it runs JavaScript and WebAssembly in the browser, so merge, split, compress, rotate, sign, redact and OCR all happen on your own machine. The site lists 25 tools and states that there is no account, no tracking and no daily limit. That makes it a fit for contracts, medical records or ID scans.
It is a one-person project, started in 2026, published under the AGPL with source code on GitHub, a Docker image for self-hosting and a Windows desktop app. For a company that needs a named vendor, a service level or a support contract, that is thin: PDF24 and Nutrient are established, while Smallpdf and iLovePDF offer more polished web workflows and collaboration features.
Redaction is a good example of the design. The vendor says the page is re-rendered as an image with the boxes burned in, so the text underneath is removed rather than hidden. Browser-side processing also means large files depend on your device and browser memory. We could not test performance, so judge it on your own files before standardizing on it.
