Are my images uploaded?
No. PhotoFormTools uses browser canvas APIs, so the selected image is processed on your device instead of being sent to an upload server.

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.
