Frequently Asked Questions
Clear answers about client-side processing, document security, and how our platform works
What is the difference between the three compression levels? ▼
Light compression preserves near-original image quality while cleaning redundant metadata. Medium provides the ideal balance for everyday sharing. High achieves maximum size reduction, especially for scanned documents.
Will text remain sharp and selectable? ▼
Yes! Text elements remain vector fonts, meaning they stay crystal clear at any zoom level.
Why do some files compress more than others? ▼
Files containing high-resolution scanned images will see massive reductions (often 50% to 80%), whereas files composed purely of plain text or already-optimized photos compress less.
