Compress PDF FAQ

Is this PDF compressor free?

Yes. Compress as many PDFs as you like with no account, no daily limit and no watermark.

Is my PDF uploaded?

No. The PDF is compressed in your browser and never leaves your device.

How does it make the PDF smaller?

Large pictures are resized and saved as efficient JPEGs. Text, fonts and drawings are left as they are, so they stay sharp and the text stays searchable.

Which level should I choose?

Recommended suits most files, including email and upload forms. Choose Strong when you need the smallest file with selectable text, and Light to keep photos at print quality.

Why didn’t my PDF get much smaller?

A PDF that is mostly text, or whose pictures are already small, has little to shrink. Scanned documents and PDFs with photos shrink the most. Maximum turns every page into a picture, which can help with complex drawings, but the text is then no longer selectable.

Will transparent pictures and logos look right?

Yes. Transparency masks are kept exactly, and special colour spaces such as CMYK print images are left untouched.

Can I compress a password-protected PDF?

Not directly. Open the file, save a copy without a password, and compress that copy.
