## New optimization features in Images

Jun 16, 2026 

[ Cloudflare Images ](https://developers.cloudflare.com/images/) 

These updates introduce new features for optimizing and manipulating with Images:

* **New `composite` option:** Control how [overlays are blended](https://developers.cloudflare.com/images/optimization/draw-overlays/#composite) with the base image.
* **Percentage widths:** Set the dimensions of an overlay as [a fraction of the dimensions](https://developers.cloudflare.com/images/optimization/draw-overlays/#width-and-height) of the base image.
* **New `fit` modes:** Use [aspect-crop](https://developers.cloudflare.com/images/optimization/features/#aspect-crop) to always preserve the target aspect ratio or [scale-up](https://developers.cloudflare.com/images/optimization/features/#scale-up) to always enlarge images.
* **New `upscale` parameter:** Apply [AI upscaling](https://developers.cloudflare.com/images/optimization/features/#upscale) to produce sharper, more detailed results when enlarging images.
