Compress a PDF to 1 MB

Free · in your browser · no upload

Choose a PDF: the scans and photos inside are saved again until the file is under 1 MB. A 10–20 MB scan usually shrinks to fit without visible loss, and the text stays selectable.

Works in your browser: what you type or choose stays on your device and is not uploaded anywhere.

Where you need this

  • Portals and forms with a 1 MB limit

Questions

My PDF is 30 MB. Will it fit in 1 MB?

If it's mostly photos or scans, usually yes. The tool tells you if even the strongest step can't reach 1 MB.

Does 1 MB mean 1,000,000 bytes?

The file always stays under 1,000,000 bytes, so it fits limits counted either way.
