How to Fix an “Image File Type Not Supported” Error
Convert unsupported HEIC, AVIF, WebP or PNG files to the format the receiving form actually accepts.
Open the toolOpen file-type repair preset →Identify the field that failed
Upload systems validate separate fields such as format, pixel dimensions, aspect ratio, background and file size. Do not change unrelated properties if the rejection message names a specific field.

Verify the current destination rule
The linked Batch Img Tools tool opens an editable repair preset. Confirm the current portal or platform requirement before final submission.
