Free PDF compression
Compress PDF files and reduce PDF size in your browser
Large PDFs bounce off email limits, slow down pages and eat storage. This tool rebuilds your document as a smaller PDF directly in your browser, with no upload and no server.
Why compress a PDF
- Stay under email attachment limits
- Load and share documents faster
- Save storage and bandwidth
- Publish lighter PDFs on your website
How it works
Every page is rendered at the DPI you pick and re-encoded as a JPEG at your chosen quality, then the pages are assembled into a new PDF. Text becomes part of the image, so the result is ideal for scans and image-heavy documents rather than files you still need to edit or search.
Made for
- Shrinking scanned documents and contracts
- Getting a PDF under an upload limit
- Optimising image-heavy PDFs for the web
Private by design
Your document is opened and rebuilt on your own device. Nothing is uploaded, stored or logged.
