Frequently asked questions — Optimize PDF

How is this different from Compress PDF?

Compress reduces image quality. Optimize strips redundant data and unused objects without touching quality.

Will text or fonts change?

No — text stays fully readable and searchable.

Does it work on scanned PDFs?

Yes, though image-heavy PDFs benefit less.

Can I optimize a password-protected PDF?

Unlock it first, then optimize.
