FAQ

Frequently asked questions

Which compression mode should I use?

Use Safe when preserving document structure is important. Balanced and Strong can reduce size more aggressively but may rasterize pages.

Can compressed text stop being selectable?

Yes. In rasterized compression modes, page content can become image-based instead of selectable text.

Will every PDF shrink by the same amount?

No. Savings depend on the document's images, fonts, existing compression and structure.
