Best use cases
- Upload forms with 100KB, 200KB, 500KB or 1MB limits.
- Email attachments and application portals.
- Website publishing where large photos slow pages down.
Balance visual quality and smaller file sizes.
The best compression result is the smallest file that still looks right at its actual destination.
There is no universal quality setting. Text, product labels, faces and screenshots show artifacts before ordinary photo backgrounds, so judge the result by the important part of the image instead of file size alone.
Most can be made smaller, but detailed photos may need smaller dimensions or visible quality tradeoffs.
WEBP is often efficient, but some upload forms only accept JPG or PNG.
Text and sharp edges show artifacts sooner than normal photo areas. Resize first and avoid excessive compression.
Use automatic mode for general sharing. Use target size when a form lists a hard maximum.
Choose a focused workflow.
