PDF tools that never see your documents
Every tool here runs inside your browser. Your files are read into memory, worked on, and written back out again without ever crossing a network. There is no server to trust, because there is no server involved.
How it works
Conventional online PDF tools upload your file, process it on a machine you don't control, then hand back a download link. That model requires you to trust a company with the contents of your documents, its retention policy, and its security.
This app takes the other approach. It uses WebAssembly builds of pdf-lib, PDF.js and Tesseract to do the same work locally. The practical upshot: you can disconnect from the network entirely and every tool still works.
What that buys you
No upload wait
Processing starts the moment you drop a file. Large documents don't spend minutes crossing a connection twice.
No account
Nothing to sign up for, no email to hand over, no password to manage. Open a tool and use it.
No file limits
There's no server bill to control, so there are no page caps, size ceilings, or daily quotas.
Works offline
Once the page has loaded, the network is optional. Useful on a plane, and useful for documents that shouldn't leave a building.
The trade-off
Local processing isn't free of cost — it spends your device's memory and CPU instead of a server's. Very large documents, OCR over many pages, and high-resolution image conversion are noticeably slower on an older machine than they would be on rented hardware. That is the price of the file never leaving, and it's a price worth naming rather than hiding.
