Questions and answers
Can this meet every application requirement?
It can target JPEG file size, but it does not verify dimensions, background, lighting, or any organization-specific photo rules.
What if the target is not reached?
Some photos cannot be encoded below a requested size at usable quality. Reduce dimensions if allowed or choose a less strict target.
Is the photo sent to the server?
The selected photo is processed in your browser and is not sent to a ResizeTool upload endpoint.
