How it works
Upload your PDF, pick a compression level, and get a smaller version back. Embedded images and unused data are shrunk so the file weighs less while still opening in every PDF viewer.
Common use cases
- Getting an oversized scan under the email attachment limit (typically 10 or 25 MB).
- Reducing a report so it uploads faster to a document management system with a per-file cap.
- Making a heavy invoice bundle small enough to share over instant messaging without triggering upload limits.
Privacy

FAQ
Which compression level should I pick?
"Smallest size" is best for on-screen reading and email — enough for a fluent read, much lighter. "Balanced" is the safe default. "Best quality" keeps enough detail for professional printing.
Is my file sent to the service?
