Why convert ICO to WebP?
ICO is the Windows icon container that bundles one or more small images used for favicons and application icons. WebP is a modern Google format offering both lossy and lossless modes, transparency, and files 25–35% smaller than JPG or PNG.
Both ICO and WebP support transparency, so transparent regions are carried across cleanly. Moving from ICO to WebP usually shrinks the file significantly thanks to WebP's efficient compression — great for websites, email, and saving storage. WebP is supported across all modern browsers and is one of the best choices for website performance and Core Web Vitals.
Pixohub converts ICO to WebP entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many ICO files into WebP as you like. Reach for WebP whenever you need fast-loading website images that keep transparency and quality.
ICO vs WebP: what to expect
ICO is best for favicons and Windows desktop icons, while WebP shines for fast-loading website images that keep transparency and quality. Keep your original ICO if you may later need the source file, and export a WebP copy for sharing and the web.
