Frequently Asked Questions
Why are some PDFs compressed more than others?
Client-side compression optimizes PDF cross-reference streams and strips uncompressed metadata. If a PDF is already filled with pre-compressed JPEG scans, structural compression yields modest improvements without lossy re-encoding.
