Rate-limiting

In order to avoid the limits, you’ll need an API key or to upgrade your account. Learn more about our rate limiting policies.

​
PNG instead of JPG

<img src="https://img.logo.dev/shopify.com?format=png" />
In some cases, PNGs with limited color palettes will result in smaller image files with less compression. Using PNGs allows for transparency, although not all logo images will be compatible.

​
Desaturated

<img src="https://img.logo.dev/shopify.com?greyscale=true&format=png" />
Desaturated logos are most useful for landing pages when you want to normalize colors across the set.

​
Light and dark modes

<img src="https://img.logo.dev/github.com?theme=dark&format=png" />
The theme parameter automatically adjusts logos for optimal visibility on different backgrounds. When set to dark, it inverts logos with dominant light colors (like white) to ensure they’re visible on dark backgrounds. Conversely, theme=light inverts dark logos for light backgrounds. This feature only works on images with transparency.

​
Resizing images

<img src="https://img.logo.dev/shopify.com?size=80" />
Our image CDN will resize to any valid integer, but we recommend staying under 600px when using raster images like jpg and png.

​
Retina images

<img
  src="https://img.logo.dev/shopify.com?size=80&retina=true"
  width="80"
  height="80"
/>
The retina=true parameter doubles the source image resolution (160px) while displaying at the specified size (80px), creating sharp images on high-density displays. Without this parameter, logos may appear blurry.

​
Fallback images

In the case where no image is found for a given domain, the API will return a black and white monogram of the first letter of the domain with HTTP Status Code 200 OK.

If you want to suppress these monograms use the parameter fallback=404 to recieve an empty response and HTTP Status Code 404 Not Found.
