About this tool
Most of a PDF’s size usually comes from the photos and scans inside it. This tool shrinks those images and leaves text and drawings untouched, so text stays sharp and searchable.
A PDF made only of text is already compact and won’t get much smaller.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser, on your own device. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page has loaded.
Which level should I choose?
Recommended keeps documents clear on screen and in print. Strong is for email and upload limits, where size matters more than detail.
Does it work with scanned documents?
Yes. Scanned PDFs are made of images, so they usually shrink the most.
Can it open password-protected PDFs?
No. Remove the password first, then compress the file.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
