Cloudflare Images - Transformation flows in Images

Wed, 27 May 2026 00:00:00 GMT

Flows are automated rules that pair conditions (such as file extension, URL path, or query parameter) with parameters. Set up a flow to automatically apply image optimization to matching requests on your zone without writing code or changing URLs.

There are two modes for transformation flows:

Provider flows — Migrate from another image optimization service. Your existing URLs continue to work while Cloudflare rewrites provider-specific parameters to their Cloudflare equivalents. Currently, Cloudflare supports provider flows for Fastly Image Optimizer.
Custom flows — Define your own conditions and actions for use cases like automatic format conversion, responsive sizing with width=auto, or directory-based optimization.

To get started, go to Images > Transformations > Automation in the Cloudflare dashboard.

Cloudflare Images - HEIC support in Cloudflare Images

Tue, 08 Jul 2025 00:00:00 GMT

You can use Images to ingest HEIC images and serve them in supported output formats like AVIF, WebP, JPEG, and PNG.

When inputting a HEIC image, dimension and sizing limits may still apply. Refer to our documentation to see limits for uploading to Images or transforming a remote image.

Cloudflare Images - Bind the Images API to your Worker

Mon, 24 Feb 2025 00:00:00 GMT

You can now interact with the Images API directly in your Worker.

This allows more fine-grained control over transformation request flows and cache behavior. For example, you can resize, manipulate, and overlay images without requiring them to be accessible through a URL.

The Images binding can be configured in the Cloudflare dashboard for your Worker or in the Wrangler configuration file in your project's directory:

wrangler.jsonc

{
  "images": {
    "binding": "IMAGES", // i.e. available in your Worker on env.IMAGES
  },
}

wrangler.toml
```
[images]
binding = "IMAGES"
```

Within your Worker code, you can interact with this binding by using env.IMAGES.

Here's how you can rotate, resize, and blur an image, then output the image as AVIF:

const info = await env.IMAGES.info(stream);
// stream contains a valid image, and width/height is available on the info object

const response = (
  await env.IMAGES.input(stream)
    .transform({ rotate: 90 })
    .transform({ width: 128 })
    .transform({ blur: 20 })
    .output({ format: "image/avif" })
).response();

return response;
