Your files never leave your browser.
Unfleece runs every PDF operation locally via WebAssembly. There is no server that receives, stores, or processes your documents — which is exactly why it can be free.
Prove it's private in 10 seconds.
Don't take our word for it. Watch the network while you work — the only requests are for the app's own code, which your browser caches. The source is open, so you can read exactly what it does.
Open any tool and press F12 → Network tab.
Run it on a file. Watch the request list.
See nothing upload. Turn off Wi-Fi — it still works.
No server, no bill, no paywall
Because all the work happens on your computer, Unfleece has no compute or bandwidth bill — so there's nothing to monetize with a trial trap. The fleeceware sites charge you for something your own device can already do.
What it can and can't do
What works great
- Merge, split, rotate, organize, crop
- Images ↔ PDF, PDF → images / text
- Watermark, page numbers, metadata, sign
- Lossless optimize & compress
Honest caveats
- Very large files are bound by your device memory
- PDF→Text is selectable text only (scans need OCR)
- Compress rasterizes — text becomes non-selectable
- We label every tool for what it actually does
Auditable by design
