The Best Free PDF Tools With No Upload (2026)
The top ways to work with PDFs privately — no sign-up, no upload, no cost.
Quick answer
The best free PDF tools with no upload run in your browser so your files stay private. Our top pick is Trace Free PDF for a complete, free toolkit with no sign-up. Squoosh, PDFgear, and Stirling PDF are also private, but each has trade-offs covered below.
1. Trace Free PDF — best all-round
A full set of PDF and image tools that work entirely in your browser. Merge, split, compress, convert, edit, and sign — free, no account, no watermark, no limits, and nothing uploaded.
2. PDFgear — good if you want a desktop app
PDFgear is free and private, but its full features live in a desktop app you install. If you'd rather not install anything, an in-browser tool is simpler. See the PDFgear alternative.
3. Squoosh — best for single images
Google's Squoosh compresses one image at a time in your browser. For batch image jobs or PDF tools, see the Squoosh alternative.
4. Stirling PDF — best for developers
Stirling PDF is open source and private, but you host it yourself with Docker. For a no-setup option, see the Stirling PDF alternative.
How we picked
- Privacy: does it upload your files? We favored tools that don't.
- Cost: free, with no watermark or hard limits.
- Ease: no install and no account to get started.
