About this tool
Each page is re-drawn as a compressed picture and put back into a new PDF. The tool tries stronger compression step by step and stops at the first result below 50 KB.
Because pages become images, text in the output cannot be selected or searched. Keep your original file. Scanned documents are unaffected by this limitation.
Up to 60 pages are supported.
Frequently asked questions
Is my PDF uploaded?
No. Compression runs in your browser; the tool loads helper libraries from a CDN.
Why can I not select text afterwards?
Pages are converted to images to reach small sizes.
What if it cannot reach 50 KB?
The tool shows the smallest size it reached. Try splitting the file or removing pages.
Is the original changed?
No. You download a new file.
