Compress PDF
Reduce PDF file size while maintaining quality. Optimize PDFs for web sharing and storage.
About Compress PDF
Compress PDF reduces PDF file size by re-encoding embedded images, making the file easier to email, upload, or store.
PDFs with photos and scans balloon in size, blocking email limits and slowing uploads. This tool shrinks the file in your browser with adjustable compression, keeping the document readable.
When to Use Compress PDF
Use it to make a large PDF fit an email attachment limit, to speed up uploading to a portal, or to archive documents more cheaply.
Pro Tip
Compress the original, not a copy you've already compressed — repeated compression degrades quality without much further size gain.
