What this tool does not silently solve for you.

The final quality depends on the source image, output format, and target file size
Exact KB targets may require smaller dimensions or a different format
Official submission rules still need to be checked on the destination site

Common issues

Fix the most frequent blockers quickly.

The output is still over 20KB. Reduce the dimensions first or switch to JPG/WebP before rerunning the export.
The image looks soft after compression. Start from a smaller crop or accept a slightly larger target when the portal allows it.
