Frequently Asked Questions

Does compressing reduce PDF quality?

Compression re-renders each page as an optimized image at your chosen quality level, so very high compression can soften image/text sharpness. 'Recommended' balances size and clarity for most documents.

Why is my compressed file still large?

Text-only PDFs are already efficient — heavy compression mainly benefits image- and scan-heavy PDFs.

Is my PDF uploaded to a server to be compressed?

No — compression runs fully client-side using your browser's rendering engine.
