Compress PDF
Scanned certificates are often too large for exam portals. Choose a level, or enter a target KB and the tool tries stronger settings until the file fits.
Your files are processed in memory and never stored.

FAQ
- Why is my PDF still large?
- PDFs made of high-resolution scans compress well; PDFs that are mostly text are already small and will not shrink much.
- Can I compress a password-protected PDF?
- No — remove the password first.
- Are my files stored?
- Files from guests are processed in memory and never stored. If you are logged in, a copy of the result is kept for 24 hours in your download history and then deleted automatically.
