How to choose a compression mode

  • Lossless: keeps text selectable and copyable — ideal for files with structural redundancy (e.g. repeatedly edited and saved);
  • Balanced: redraws each page as a high-quality image, typically cutting size by 50–80% — the best daily choice for sharing;
  • Extreme: lowers resolution further — for reading on a phone screen or strict email attachment size limits.

Compression runs entirely in your browser — files never touch any server. For large files, speed depends on your device; please be patient.
