Convert WebP to ICO
Turn WebP images into ICO icons for favicons and Windows. Everything happens in your browser, so your images never leave your device.
Why convert WebP to ICO?
WebP is great for websites, but plenty of apps, upload forms and print services still won't take it. ICO is the format browsers look for at /favicon.ico and the one Windows uses for app and shortcut icons.
Transparency is kept
Both WebP and ICO support transparency, so transparent areas carry over without a fill colour.
Animated WebP files
If your WebP is animated, only the first frame is converted and you get a still ICO. Non-animated WebP files convert as normal.
Favicons and Windows icons
Browsers still request /favicon.ico from websites, and Windows uses ICO for application and shortcut icons. Icons are square and the ICO format tops out at 256 × 256 pixels, so a square, simple WebP works best; fine detail disappears at 16 × 16.

Questions
Can I convert an animated WebP?
Yes, but only the first frame is kept, so you get a still ICO.
Will converting WebP to ICO reduce quality?
ICO stores icons losslessly, but the format tops out at 256 × 256 pixels, so start from a square WebP at that size or below and keep the design simple enough to read at 16 × 16.
Are my WebP images uploaded anywhere?
No. The conversion runs in your browser, on your own device, so your images are never sent to a server. Once the page and converter have loaded, it keeps working even if your connection drops.
