# Image Watermarking

> Automatically protect and brand your images with custom watermarks

Bunny Optimizer can automatically apply watermarks to your images to protect intellectual property, reinforce branding, or mark user-generated content.

> [!NOTE]
>
> Watermarks are applied during the optimization process and cached. There's no
> performance penalty after the first request.

## Configuration

Access watermarking settings in **Optimizer** → **Settings** → **Watermark images**

![Enable Watermarking](https://mintcdn.com/bunnynet-cb9733c2/54-4KCQKoNVNuoyW/images/optimizer/image-watermarking.png?fit=max\&auto=format\&n=54-4KCQKoNVNuoyW\&q=85\&s=fd8638d0562c626c61b022e8e7ceed0c)

### Watermark image URL

The publicly accessible URL to your watermark PNG (transparency supported).

**Best practices:**

* Use PNG format with transparency
* Design at 2x resolution for sharp display
* Keep file size under 100KB
* Test on both light and dark images

### Minimum image size

Only images with width OR height greater than this value will be watermarked (in pixels).

**Example:** Setting this to 800px prevents watermarks on small thumbnails while protecting larger downloads.

### Position

Choose from a few different placement options:

* Bottom Right
* Bottom Left
* Top Right
* Top Left
* Center
* Center Stretched

### Border offset

Distance from the edge as a percentage (0-100%).

**Example:** 5% offset on a bottom-right watermark places it 5% away from both the bottom and right edges.

## Combining with Dynamic Images API

Watermarking applies after Dynamic Images transformations, ensuring your watermark appears on all generated variants.
