Supported formats and limitations

Cloudflare Image Resizing can:

  • Read JPEG, PNG, GIF (including animations), and WebP images.
  • 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.

Cloudflare Image Resizing does not:

  • Support SVG since this format is inherently scalable and does not need resizing.
  • Support HEIC (HEIF) format. Cloudflare does not plan to support this format.

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

​​ Maximum sizes

Maximum image size is 100 megapixels (for example, 10,000×10,000 pixels large). Maximum file size is 70 MB. GIF animations are limited to 100 megapixels total (sum of sizes of all frames).
