FAQ
How to balance quality and size?
Keep 100% scale first and tune quality to 70-80; then reduce scale in 10% steps watching the savings percentage.
It says 0% saved — why?
The source is already well compressed; further quality loss would be visible. Lower the scale for real size reduction instead.
Is my image uploaded?
No, everything runs locally in your browser.
