Frequently Asked Questions

How much will it compress?
Results vary. This tool re-encodes cross-reference tables. Typical savings are 5–40% on PDFs with uncompressed metadata; scanned PDFs may see little change.
Are my files uploaded?
No. Everything runs in your browser.
Why is my compressed file larger?
Some PDFs are already fully optimised. If the output is larger, use the original.
