Frequently asked questions

How much smaller will it get?

PDFs with photos or scans often shrink by half or more. Text-only PDFs are already small and shrink little.

Is text affected?

No. Only images are recompressed.

Is there a size limit?

PDFs up to 100 MB. Password-protected PDFs need the password removed first.
