FAQ
How does PDF compression work?
Embedded images are re-encoded at your chosen quality level; text and vector content stay untouched and sharp.
Why is my PDF barely smaller after compressing?
If a PDF is mostly text or already-optimized images, there is little to compress. Scanned documents shrink the most.
Is my PDF uploaded?
No — compression runs entirely in your browser.
