How to compress a PDF
Shrink a large PDF so it's easy to email or upload — without sending your file to a server.
1. Add your PDF
Drop in any PDF; it's processed entirely in your browser.
2. Pick a level
Choose how hard to compress — balance smaller size against visual quality.
3. Download
Get the slimmed-down PDF and see exactly how much you saved.
PDF compression is handy for email attachment limits, web uploads, portfolios and forms. This tool re-encodes the images embedded in each page at a lower, adjustable quality and rebuilds the document, which is where most PDF bloat lives. Because it runs locally, confidential contracts and scans never leave your device. For converting pages to images instead, try PDF to JPG.
