Quick answer
To compress a PDF, choose a level and press Shrink. Gentle mode tidies the file and keeps text selectable. Stronger levels turn pages into compressed pictures for bigger savings on scans and photo-heavy files.
How hard to squeeze
Balanced, Strong and Tiny turn each page into a compressed image, so text can no longer be selected.

Frequently asked questions
Why is my file barely smaller?
Files that are mostly text are already compact. Savings are largest for scans and photo-heavy PDFs.
Does it ever make the file bigger?
Picture-based levels can for text-heavy files. In that case the tool automatically returns the smaller gentle result instead.
Where do my files go?
Most tools work entirely inside your browser tab, so the PDF is processed on your device and not uploaded to us. The AI tools are the exception: with your own key, the text of your PDF is sent to the AI provider you choose, and they say so before you start.
Do I need an account, and is there a limit?
No account, no watermark and no daily limit set by the site. Very large files are limited only by your device’s memory.
