Why this preset works
This preset aims for a final file no larger than 20KB. The optimizer first searches for the best encoding quality, then carefully reduces dimensions only when quality changes are not enough.
Best for Strict online application limits Avatars and profile photos Low-bandwidth sharing

Useful answers
Questions about 20kb image reducer
How do I compress an image to 20KB?+
Upload the image and select Compress. The tool searches encoding quality and dimensions until the result is 20KB or smaller whenever the source permits it.
Why might dimensions change?+
Some images cannot reach a strict limit through quality alone. The tool progressively reduces pixel dimensions rather than claiming a target it did not meet.
Is target-size compression private?+
Yes. CompressMint processes images locally in your browser. Your photos are not uploaded to our servers, and refreshing the page clears the working session.
