Compress PDF
Most large PDFs are large because of the photos or scanned pages inside them. Compress PDF finds those images, resizes them to a sensible resolution and re-saves them at a lower JPEG quality, then rebuilds the file more compactly. Text, fonts, links and vector drawings are left untouched, so they stay sharp and selectable.

Frequently asked questions
- Why did my PDF not get smaller?
- If it contains mostly text, vector graphics or images that are already compressed, there is little to gain. The tool only downloads a file when it is actually smaller.
- Which images are compressed?
- JPEG photos and scans in RGB or grey. Images in other formats, and CMYK print images (whose colours could shift), are kept as they are.
- Are my files uploaded to your server?
- No. The PDF is opened and processed by your own browser, so it never leaves your device. That also means very large files depend on your device's memory.
