Nothing is uploaded
Every tool runs as JavaScript in your browser (pdf-lib and pdf.js). The department server never sees the file — safe for personal documents such as ID cards or transcripts.

-
Set the options and runEach tool has its own options — page ranges, number position, compression level. Adjust them, then press the pink button.
-

Tips
- Hitting an upload size limit? Run Compress before attaching.
- Photographed a document? Scan straightens and sharpens it into a proper PDF.
- Password-protected files must be unlocked before they can be edited.
HOW IT WORKS
How it works and how safe it is
Speed depends on your device
Because processing happens locally, files of tens of MB or hundreds of pages can take a moment, especially on phones. Split large jobs into smaller batches.
Password-protected PDFs
Files locked with a password must be unlocked in your PDF reader first — these tools never bypass or crack passwords.
