When this helps

  • Reduce a scan that exceeds an email provider's attachment limit.
  • Shrink a proposal or portfolio before sending it to a client.
  • Make a document faster for recipients to download on mobile data.

Tips for a clean result

  • Check the compressed file size before attaching it because provider limits can differ.
  • If the result is still too large, split out only the pages the recipient needs.

Frequently asked questions

How much smaller will it be?+

It depends on the content; scanned and photo-heavy PDFs shrink the most. If we can't beat the original, you get the original back.

Will the text stay selectable?+

Compression re-encodes pages as images, so text becomes part of the image. Use it when small size matters most.
