Frequently Asked Questions
How much can I reduce file size?

Is my image private?
Yes — 100%. Everything runs in your browser. No server involved, no image data transmitted, no storage anywhere.
JPEG vs WebP — which is better?
WebP produces 25–35% smaller files than JPEG at the same quality. Use WebP for web, JPEG for maximum compatibility.
What quality setting should I use?
75% is the sweet spot — excellent visual quality with 60–70% size reduction. Go higher for print, lower for web thumbnails.
