Shopify rule
Shopify: JPG, PNG, GIF, WebP accepted (JPG/WebP recommended)
Shopify accepts JPEG, PNG, GIF, and WebP for product media. For product photography, JPG and WebP deliver the best size-to-quality ratio; PNG is best for product cutouts with transparency. HEIC is not a supported upload format - convert it first.

What we check
CatalogPrep reads the file mime type and confirms it is in the Shopify-accepted list (JPEG, PNG, GIF, WebP), flagging HEIC sources that must be converted before upload.
How to fix
Use CatalogPrep's HEIC-to-JPG tool to convert HEIC sources, then upload. CatalogPrep's export pipeline can target WebP for the best size-to-quality ratio.
