Convert ICO to WebP
ICO is the Windows icon format, used for favicons and application icons. Converting to WebP is a size decision: WebP reaches a comparable picture in a smaller file, which is why modern sites serve it. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your ICO files below and download WebP in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.

Why convert ICO to WebP?
ICO files bundle one or more icon sizes into a single file that Windows and browsers use for favicons and app icons. Regular image viewers often refuse to open them, and most editors cannot save them, so a converter is the practical way in or out of the format.
Google designed WebP to replace both JPG and PNG on the web, and it typically compresses 25 to 35 percent smaller at similar quality. It handles both lossy and lossless modes and supports transparency. Support is excellent in browsers but still patchy in older desktop software.

What changes when you convert ICO to WebP
| What happens | |
|---|---|
| Image quality | Depends on the quality setting above, which controls how much detail WebP keeps. |
| Transparency | Kept. WebP stores an alpha channel, so cut-out backgrounds and soft edges survive. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the WebP file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. ICO files here are single images. |
| File size | Smaller in almost every case, which is the reason for the conversion. How much smaller depends on the picture, so no figure is quoted here. |
