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
