# Apply blur

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/images/optimization/hosted-images/blur-variants/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

You can apply blur to image variants by creating a specific variant for this effect first or by editing a previously created variant. Note that you cannot blur an SVG file.

Refer to [Resize images](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/images/optimization/hosted-images/create-variants/) for help creating variants. You can also refer to the API to learn how to use blur using flexible variants.

To blur an image:

1. In the Cloudflare dashboard, go to the **Hosted Images** page.  
[Go to **Hosted images** ↗](https://dash.cloudflare.com/?to=/:account/images/hosted)
2. Select the **Delivery** tab.
3. Find the variant you want to blur and select **Edit** \> **Customization Options**.
4. Use the slider to adjust the blurring effect. You can use the preview image to see how strong the blurring effect will be.
5. Select **Save**.

The image should now display the blurred effect.
