# Logo and favicon

Use **Logo and favicon** to upload your company logo and favicon in the courses. Add logos directly from your device or select from the platform's resource library, or access professional stock imagery from Unsplash's extensive library as an alternative to custom logos.

**Logo** appears in the course header (top of all course pages):

<figure><img src="/files/GrOpOMGNLOaVHrp6XhKP" alt=""><figcaption></figcaption></figure>

## Logo requirements

* **Recommended dimensions**: Use a 1:1 aspect ratio, or a layout where the width is greater than the height.
* **File size**: No strict limit, but a size under 10 MB is recommended for optimal performance.
* **Supported formats**: JPG, JPEG, PNG, SVG, WEBP.
* **Responsive considerations**: Complex logos with fine details may become illegible on mobile devices.
