​
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/apple.com?theme=dark&format=png" />
The theme parameter adjusts logo colors for visibility on your background.
  • theme=dark: Use when displaying logos on dark backgrounds. Inverts light-colored logos (e.g., white logos become black).
  • theme=light: Use when displaying logos on light backgrounds. Inverts dark-colored logos (e.g., black logos become white).
This feature requires 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.

https://img.logo.dev/example.com

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