Your documents never leave your device.
Merge, split, OCR and manage PDFs entirely inside your browser. Not one byte is sent to a server — because the safest place for a confidential file is the device it already lives on.

How your privacy is guaranteed
Not a policy. Not a pinky-promise. The way the software is built.
Runs on your machine
Every operation executes locally through WebAssembly. Your processor does the work — there is no server in the loop.
Nothing is uploaded
Files are read into memory inside your browser and never transmitted. Switch off your internet mid-task and it still works.
Nothing is stored
No account, no logs of your documents, no retention. Close the tab and every trace is gone for good.
Most online PDF tools upload your files. We can’t.
There’s a structural difference between “we promise not to look” and “we never receive it.”
Typical online PDF tools
- Your file is uploaded to a remote server
- Copies linger in the cloud and in backups
- Privacy rests on a policy you have to trust
- One breach can expose your documents
The local-first way
- Your file never leaves the browser tab
- Nothing is stored, anywhere, ever
- Privacy is enforced by the architecture
- There is no server holding anything to breach
Open any tool. Watch the network tab.
Nothing leaves. No sign-up, no upload, no catch — just fast, private document tools that work the moment the page loads.
