Compression note

Strong PDF compression rebuilds pages as images. This can reduce file size substantially but may remove selectable text, forms, links and other interactive PDF features.

How to use the Compress PDF

  1. Choose a PDF from your device.
  2. Choose the desired quality.
  3. Compress the document.
  4. Compare the original and compressed sizes and download the result.

Examples

Smaller email attachment

Reduce the size of a scanned PDF before attaching it to email.

Smaller upload

Compress a PDF before uploading it to a portal with a file-size limit.

Frequently asked questions

Is the PDF uploaded?

No. Compression is performed locally in your browser.

Can compression affect PDF features?

Strong compression rebuilds pages as images, so selectable text, forms, links and other interactive features can be lost.
