Compress PDF files online
File upload
Shrink your PDF, keep it readable
Compression cuts file size so your files fit email limits and upload portals - you choose how much quality to trade.
Choose the trade-off yourself
Pick a lighter compression for sharing or a higher-quality setting for printing; each option shows what you're trading before you commit.
See exactly what changed
The tool shows size before and after, and says so directly if a file was already as small as it can get.
Long documents up to 100 MB
Scanned reports and image-heavy PDFs compress in one pass, no splitting required.
No installs, just a browser
Compress from a phone, tablet, or laptop wherever you are.
Files stay private
Encrypted in transit and deleted after 30 days unless you sign in to keep them.
Share the smaller file directly
Download it, email it, or copy a share link the moment compression finishes.
