PDF compression questions
Which PDFs compress best?
Scans and image-heavy PDFs usually shrink the most. Already optimized or mostly text-based PDFs may not become smaller.
Does compression preserve selectable text and forms?
No. This compression method creates an image-based copy, so selectable text, links, form fields, and annotations are flattened.
