- Click Compress and download the smaller PDF.
Frequently asked questions
Which PDFs compress best?
Documents with photos and scanned pages. Files made mostly of text and vector graphics are already compact and shrink little.
What if the file doesn't get smaller?
Then you get the original file back unchanged — the result is never larger than the source.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
Are my files uploaded to a server?
No. Everything runs in your browser, so your files never leave your device.
