How to Create an ICO Favicon from a PNG Logo
A favicon is tiny, so clarity matters more than detail. A simple square PNG logo with strong contrast usually produces a more recognizable ICO file than a full wordmark or a detailed photograph.
Prepare a favicon-friendly PNG
Start with a square PNG. Crop away empty space and simplify the artwork so the main shape remains recognizable at a very small size. Strong contrast between the icon and its background helps.
Avoid tiny text, fine lines, and complex gradients. They can disappear or look noisy in a browser tab.
Convert the logo to ICO
Upload the PNG, choose ICO as the target format, convert it, and download the ICO file. Inspect it at small sizes before publishing it on a website or using it in a shortcut.
Keep the original PNG too. It is the easier source to edit if you later change the brand mark or need a different icon size.
Use the icon on a website
Place the finished favicon file in your website's public assets and reference it through the site's favicon configuration. Browsers can cache favicons aggressively, so a changed icon may take time to appear everywhere.
For a professional site, test the icon in a browser tab, bookmark, and mobile home-screen workflow where relevant.
