Questions and answers

Compress PDF FAQ

Will text remain selectable?+

Compression rasterizes pages, so selectable text and links may not remain interactive.

Why is my file not much smaller?+

A PDF that is already optimized may have little removable size.

Which preset should I use?+

Balanced is a good first choice for everyday documents.

Should I keep the original?+

Yes. Review the compressed copy before replacing an important original.
