Supported formats and limitations

Cloudflare Image Resizing can:

• Read JPEG, PNG, GIF (including animations), and WebP images. SVG is not supported, since this format is inherently scalable and does not need resizing.
• Resize and generate JPEG and PNG images, and optionally AVIF or WebP.
• Save animations as GIF or animated WebP.
• Support ICC color profiles in JPEG and PNG images.
• Preserve JPEG metadata. Metadata of other formats is discarded.
• Convert the first frame of GIF animations to a still image.

AVIF format is supported on a best-effort basis. Images that cannot be compressed as AVIF will be served as WebP instead.
