- Always check the compressed file before sharing to verify quality
Frequently Asked Questions

Default and Light compression preserve high quality for most documents. Extreme compression may reduce image quality noticeably but achieves the smallest file size.
Results vary depending on the content. PDFs with large images typically see the biggest reduction, while text-only files are already compact and may shrink less.
