Why convert ICO to WebP?
ICO is the Windows icon container, used for application icons and website favicons. It can hold one or more small images, typically 16x16 up to 256x256 pixels. WebP is a modern Google format that compresses 25-35% smaller than JPG and PNG at similar quality, while supporting both transparency and animation.
- Shrink file size — WebP typically produces noticeably smaller files than ICO, which speeds up websites and saves bandwidth.
- WebP compression makes the image far smaller than ICO; use the quality slider to balance size against sharpness.
