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.
Make images smaller for email attachments.
Email problems are often caused by several large camera photos rather than one unusually large file.
Compress the batch to a practical attachment size, then make sure the recipient's mail service and the final image dimensions still match the purpose of the photos.
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.
