Compress PDF

Reduce PDF file size without losing quality

Compress your PDF files to reduce their size for easier sharing via email or uploading. Choose from different compression levels to balance quality and file size.

How to Compress a PDF

Upload your PDF, choose a quality preset, and click Compress PDF. The tool re-renders each page as a compressed JPEG image and builds a new, smaller PDF. After processing, you can see the before and after file sizes before downloading.

Understanding Quality Presets

The Low preset renders at 1x scale with 50% JPEG quality — ideal for archiving or previewing. Medium uses 1.5x scale at 70% quality, balancing clarity and size. High renders at 2x with 85% quality for near-lossless visual fidelity at a moderate size saving.

Common Use Cases

  • Reducing large PDF attachments for email
  • Making PDFs faster to load on websites
  • Fitting documents within storage or upload size limits
  • Archiving documents at a smaller storage footprint
