FAQs
Why can a “compressed” PDF become larger?
If the original is mostly vector/text (very compact), rasterizing pages into JPEG images can increase size. Use Lossless Optimize to keep vector text.
What does Lossless Optimize do?
It re-saves the PDF using compact object streams and strips common metadata, preserving selectable text and links.
Best settings for scans?
50–70% usually preserves readability while shrinking size significantly.
