When and how to use Compress PDF

Compress PDF is meant for reducing PDF size without losing control over readability, delivery constraints, or output quality.

The key controls on this page are Profile, Keep Quality Hint, Fast Mode. Check them before you process final files.

If this run affects client delivery, approval, or archive quality, validate the output once before you share it. The related how-to and use-case pages below cover the most common real-world edge cases.

Best practices

  • Match compression strength to the delivery goal first, then check small text and image-heavy pages before sharing.
  • Use balanced defaults first, then increase processing strength only when required.
  • Validate output readability on both desktop and mobile before sharing.

Common issues

  • Aggressive settings can make scanned pages, diagrams, or fine-print text harder to read than expected.
  • Range syntax errors can skip required pages.
  • Large scans can remain heavy until OCR and cleanup are combined.
