Most tools here run inside your browser. The file is opened on your own device and the result is made there too, so it is never uploaded to our servers. That makes them safe for contracts, IDs, payslips and client files, and they keep working on slow connections because nothing large is sent. You also do not need to install software or create an account. Every tool saves a new copy, so your original file stays exactly as it was.
