Smallpdf offers a polished, well-designed PDF toolkit aimed at quick everyday tasks. The defining difference is where your files are processed: Smallpdf uploads your documents to its servers, while ihatepdf does everything locally in your browser using WebAssembly — your files never leave your device. It is free, needs no sign-up, adds no watermark, and has no artificial limits.
ihatepdf is a free Smallpdf alternative that runs entirely in your browser. Unlike Smallpdf, it never uploads your files to a server, needs no account, adds no watermark, and has no file-size or usage limits. Every tool works offline once the page loads, so your documents stay completely private.

When you upload a document to Smallpdf, that file travels over the internet and is processed on its servers. For confidential files — contracts, CVs, financial and medical records — that is an avoidable exposure. ihatepdf removes it by never asking your files to leave your device: all processing happens in your browser tab using the same C/C++ libraries (compiled to WebAssembly) that power professional desktop PDF software. You get comparable results with none of the upload, none of the watermarks, and none of the sign-up friction.
