A while back I got tired of using PDF tools that force you to upload your file to a server just to do something simple like merge two PDFs or compress a scanned document. So I built pdfcevir — a small toolkit where everything happens client-side, in the browser.
The problem
Most free PDF tools online work the same way: you upload your file, their server processes it, then you download the result. That's fine for most use cases, but it means:
Your file (which might be a contract, an ID scan, a private document) sits on someone else's server, even briefly
You're limited by their server's speed and uptime
