When it helps

Compression helps when sending scans, decks, and reports. Stronger compression means a smaller file, but aggressive settings can hurt image quality.

How to use the tool

  1. Open the Compress PDF page.
  2. Upload one or more PDFs to the dropzone.
  3. Choose a compression level: Recommended (75%), Medium (50%), or Maximum (25%) — start with Recommended.
  4. Click compress and wait for processing.
  5. Download the compressed file and compare the size.

Tip. If text looks blurry, try a higher quality setting or remove unused pages first.
