Compress PDF

Scanned documents often make PDFs too big for online forms or email. This tool shrinks them by saving every page as a lighter image.

How to use

  1. Choose or drop a PDF.
  2. Choose how strongly to compress.
  3. For colour scans of text documents, Black & white can make the file smaller still.
  4. Check the new size and click Download.

How it works

Each page is redrawn as an image (72, 100 or 150 DPI) and saved with JPG compression. This works best for scanned PDFs. For PDFs made on a computer, text will no longer be selectable after compression.

Frequently asked questions

Which PDFs shrink the most?

Scanned documents and PDFs made from phone photos usually shrink a lot. PDFs that are mostly typed text may not get smaller — in that case the tool tells you and keeps your original.

Will I still be able to copy text?

No. Pages are saved as images, so text cannot be selected or searched afterwards. Keep your original file if you need that.

How do I get under a size limit like 1 MB?

Start with Medium. If the file is still too big, try Strong and Black & white.
