Compress PDF Smaller file, same pages · takes PDF

Two strategies run and the smaller winner is kept. If neither beats the original, you get the original back and it says so.

How it works

Re-save first. The document is rewritten with object streams and any leftover, unreferenced data dropped. Text stays selectable. Savings are modest but free.

Then downsample. Every page is rendered at the chosen resolution (300, 150 or 72 DPI) and rebuilt as a JPEG. This is where scans and photo-heavy files shrink a lot, and where text stops being selectable. The result tells you when that happened.

Honest by construction. A "compressed" file that is bigger than the input is never shipped. Ties go to the version whose text you can still select.
