Compress PDF online free
Email and upload portals often reject bulky PDFs. Shrink the file with Strong, Balanced, or Light compression on your device — pages are re-encoded as images so scans and image-heavy exports fit attachment limits.
How it works
Add a PDF (max 10MB).
Pick Strong, Balanced, or Light compression.
Compress on your device and download the result.
Why this tool
- Three clear quality levels
- Runs on your device — nothing uploaded
- Built for email and portal limits
- Free within stated limits
Frequently asked questions
Will compressing a PDF reduce quality?
Strong compression saves more space and may soften images; Balanced and Light keep more detail. Pages are flattened to images, so text is no longer selectable.
Do my PDFs get uploaded?
No. Compress PDF runs in your browser on your device.
Is Compress PDF free?
Yes for light jobs online — no account required within the file size limit.
