Compress PDF

Shrink scanned and image-heavy PDFs, by level or to an exact size.

Scanned PDFs are big because each page is a high-resolution photo. This tool re-renders each page at a lower resolution and JPEG quality, which often cuts the size by 70–95%.

Because pages become images, text in the result is not selectable. For text-only PDFs that are already small, the original may stay smaller.

How to use it

  1. Choose your PDF file.
  2. Pick the options you want.
  3. Press the button to compress it, then download the new PDF.

Questions

How much smaller will my PDF get?

Scanned documents usually shrink by 70–95%. PDFs that are mostly text may not shrink at all.

Are my files uploaded to a server?

No. The tool runs entirely in your browser using JavaScript, so your files never leave your device. You can even disconnect from the internet after the page loads and it keeps working.

Is it free?

Yes, free with no sign-up, no watermark and no daily limit.
