Why these tools don't upload your file

Most online PDF tools work by uploading your file to a server, processing it there, and sending the result back. That means a copy of every document — contracts, tax forms, medical paperwork, signed agreements — passes through infrastructure you don't control, however briefly.

Every tool on this page runs the same operation entirely inside your browser tab instead — some in a background Web Worker so large files don't freeze the page. Open your browser's network tab, use any tool above, and watch: nothing is sent anywhere.
