Check the actual input
Confirm that the file opens locally and is not an HTML error page saved with an image extension. A browser's displayed picture and the file you downloaded are not always the same resource.
Export when necessary
- Read the search service's accepted formats.
- Try the original supported file.
- Export a JPEG or PNG copy if required.
- Check dimensions, transparency and orientation.
Facehunch accepts WebP along with JPG and PNG within its stated file-size limit. Converting a supported file simply to change its extension adds work without necessarily improving search results.
Preserve the evidence
If the WebP contains transparency, inspect how a converted JPEG fills the background. Keep the source-page link and note any conversion used. A format change helps compatibility; it does not expand the provider's index or prove that a no-result photograph is unpublished.
