WebP is a modern image format from Google that offers JPG-equivalent quality at 25-35% smaller size. Supported by all modern browsers, WebP is now the de facto standard for web images. However, WebP isn't always ideal — especially when you need ICO.
ICO brings the advantage: Standard Windows icon & browser favicon, auto-generated at the right size.
With FORMATTO, you can convert WebP to ICO in seconds. Everything runs 100% on your device — files are never uploaded to any server, so your privacy is guaranteed. Did you know? WebP supports both lossy and lossless modes, plus animation and transparency in a single format.
