FAQ
Frequently asked questions
- How does in-browser compression work?
- Each page is re-rendered as an optimized image and rebuilt into a new PDF. This works best for scanned or image-heavy documents.
- Will text stay selectable?
- Because pages are rasterized for maximum size reduction, text becomes part of the image. For documents where selectable text matters, use a lighter level or keep the original.
