WEBP to ICO Converter Online

Every website needs a favicon. It is the small mark in the browser tab, the bookmark entry, the history list, and the shortcut on a desktop, and a missing one makes a site look unfinished in a crowded tab bar. Browsers request it automatically, so getting it right takes one file in one predictable place. The format behind it is ICO, Microsoft’s icon container, which is still the most universally recognised option even though modern browsers also accept PNG and SVG icons through markup.

WEBP is increasingly where logos live, because it is small and keeps transparency. The problem is that WEBP is not accepted as a favicon by every browser and operating system, while ICO is. Converting the logo from one to the other bridges that gap in a couple of seconds, and because your artwork already has an alpha channel, the icon keeps its transparent background rather than arriving as a white square. That single detail is usually the difference between an icon that looks designed and one that looks pasted.

How the output is sized matters here, so it is worth stating plainly. The ICO format caps an icon at 256 pixels, and this tool writes a single icon at that limit, scaling the image down automatically if the source is larger. It does not bundle several resolutions into one container the way a dedicated favicon generator does. For best results, start with a square WEBP of about 256 by 256 pixels so the icon is a clean downscale rather than a stretched rectangle. Anything already under 256 pixels is written at its own size without being enlarged.

Non-square sources are worth a moment of preparation. The conversion scales the image rather than cropping it, so a wide logo ends up letterboxed inside a square icon and may look smaller than expected. Cropping to a square before you upload gives a noticeably better result, and simple bold marks survive the drop to 16 pixels far better than detailed photographs do, because icons are read at a glance and clarity beats detail every time.

Once downloaded, place the file in your site root as favicon.ico and browsers will find it automatically, or reference it explicitly from your markup. The whole conversion runs in your browser, so your logo is never uploaded, and there is no account to create, no watermark, and no limit on how many icons you make. Testing the result in a real browser tab takes seconds and is worth doing before launch.
