Get an image with a 1x1 aspect ratio. Typically the dealer will provide this. If you are the one choosing the image, try to choose an image with little to no text if possible. It is recommended that the image is at least 310x310 resolution.
Navigate to https://favicomatic.com/ and select “Every damn size, sir!”. Drag and drop the image to the screen to upload it. Once the image is uploaded the page will refresh and automatically download a zip file containing the new converted images.
Navigate to your download folder and extract the zip file. Navigate to the newly extracted folder.
Your favicons and a code snippet will be inside.
