How to compress a PDF

Compressing a PDF reduces its file size so it is easier to email or upload elsewhere. You pick a compression level and download a smaller file — your browser rewrites the structure and re-encodes images on your device.

  1. Open a PDF.
  2. Choose Low, Recommended, or High compression.
  3. Run Compress and wait a moment.
  4. Compare the before-and-after size and download the result.

Frequently asked questions

Will compression reduce quality?

Low compression avoids image recompression; Recommended and High may re-encode images to save more space.

Can the file end up larger?

No. If a smaller version can't be produced, the original is kept, so a 0% result is a valid outcome.

Does compressing remove private data?

No. Compression changes size, not content. Use redaction to remove sensitive information.
