Add a password to keep a sensitive file private.
How it works
1. Upload your file
Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.
2. We process it
Your file runs through an isolated job dedicated to Protect PDF, with clear progress so you always know what stage it's at.
3. Download the result
Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.
Your file stays private
Protect PDF runs in an isolated processing job. Your upload and the generated result are deleted automatically after your download window ends — we don't keep copies, and download links are random, single-purpose, and expire.
