Compress PDF: reduce PDF file size, free

Shrink large PDFs, especially scans and photo-heavy documents, so they fit email limits and upload forms. Choose low, medium or high quality.

How to use it

  1. Drop your PDF in the box above.
  2. Choose a compression level. Lower quality makes a smaller file.
  3. Tap Convert and compare the new size before downloading.

Questions

How much smaller will my PDF get?

Scans and photo PDFs often shrink a lot. PDFs that are mostly text may not shrink much.

Will the text still be selectable?

No. Compression turns each page into an image, so text can no longer be selected or searched. Keep the original if you need that.

Which files compress best?

Scanned documents and PDFs made from photos.
