## New optimization features in Images

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

Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/changelog/post/2026-06-16-new-optimization-features/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

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.
