FAQ
Will the output always match the target size?
The tool aims for the selected KB limit or pixel size. Very detailed images may need lower quality, smaller dimensions, or a second export.
Can I use the result for application forms?
Yes, but always check the final upload rules for file type, dimensions, background, and maximum size before submitting.
