It might be helpful to differentiate between render-impacting and non-render-impacting metadata, and not be specific about the EXIF metadata format. Encoders often want to put non-render-impacting metadata after the image data, so that image data is received (and in the case of progressive formats, can be painted) ASAP. See for instance, the suggested order of "extended" WebP metadata: https://developers.google.com/speed/webp/docs/riff_container#extended_file_format Some formats may go further and mandate, rather than suggest, that EXIF come after. I think JPEG-XL does this? (though, IIRC, it has special-purpose format-specific metadata fields for render-impacting things like orientation and resolution that must come before image data). cc: @jonsneyers -- GitHub Notification of comment by eeeps Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4929#issuecomment-714726361 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
