Google Business Profile generally supports landscape images. Portrait images and multi-frame
images could give an error of “Multiframe images not supported”. Please rotate the image to
landscape and try again.
WebP, HEIC, HEIF, and AVIF images are converted to JPEG before posting, and the conversion preserves the image’s color rendering and writes a small XMP packet carrying only the Iptc4xmpExt:DigitalSourceType AI disclosure, when the image declares one. No other metadata is carried over: not EXIF, and nothing else from the original XMP, so a location, a creator name or a copyright line can’t be published by accident. The
C2PA signature does not survive a re-encode.
