WebP is a modern format from Google that produces much smaller files than JPG or PNG at the same quality, with optional transparency. It is supported by every modern browser and is widely used to speed up websites.
ICO is the Windows icon format used for application icons and website favicons. The image is resized into the standard icon sizes Windows and browsers expect for favicons.
FreeConvertImg converts your WEBP files to ICO entirely inside your browser — nothing is ever uploaded to a server, so the process is instant and completely private. There are no watermarks, no sign-up and no limits. Convert a single image or a whole batch at once, then download each ICO file individually or all of them together in a ZIP archive.
Frequently Asked Questions
Why convert WEBP to ICO?
ICO is the format Windows and browsers use for icons and favicons, so converting lets you use your image as one.
Which icon sizes are produced?
The converter outputs the standard favicon sizes so the icon stays sharp in browser tabs and on the desktop.
Are my files uploaded to a server?
No. The entire conversion runs locally in your browser, so your files never leave your device.
