Free ICO to WebP converter online
Need a WebP instead of a ICO? This free converter turns ICO files into WebP images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.
ICO is the Windows icon format and the classic format for website favicons. A single .ico file can hold several sizes (16x16, 32x32, 48x48 up to 256x256) so the operating system or browser can pick the sharpest one.
WebP is a modern format created by Google for the web. It is typically 25 to 35 percent smaller than an equivalent JPG and supports transparency and animation, which is why so many websites now serve it. The downside is compatibility: older versions of Photoshop, Windows Photo Viewer, many printers and lots of upload forms still cannot open WebP files.
