WebP to ICO Converter
Turn WebP files into ICO in seconds. Everything happens on your device: nothing is uploaded, and there's no limit.
Your images are processed in this browser tab and never uploaded.
Why convert WebP to ICO?
Many apps, print services and older programs still don't accept WebP.
Browsers and Windows need ICO for favicons and app icons.
What to expect
- One ICO file is created with 16, 32, 48, 64, 128 and 256 pixel sizes. Non-square images are centred on a transparent square.
- Converting to ICO keeps every pixel of your WebP, but it can't restore detail that WebP compression already removed.

About the formats
WebP (WebP, 2010) is Google's modern web format. It makes files roughly 25–35% smaller than JPG or PNG at the same visual quality and supports both transparency and animation.
ICO (Windows Icon, 1985) is the icon format used by Windows and by website favicons. One ICO file can hold several sizes (16×16 up to 256×256), so the right one is shown in tabs, desktops and taskbars.
Frequently asked questions
How do I convert WebP to ICO?
Drop your WebP files into the box above (or tap Select files), check the options, then press Convert. Each ICO downloads on its own, or you can download them all as one ZIP file.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Your WebP files are never sent to a server, so they stay private, and it works even on a slow connection once the page has loaded.
Is there a limit on how many WebP files I can convert?
No. Convert as many as you like, for free, without signing up. Very large batches are processed one after another so your browser stays responsive.
What size should a favicon be?
Modern sites use a 32×32 favicon, with 16×16 for older browsers and larger sizes for shortcuts. This converter puts 16, 32, 48, 64, 128 and 256 pixel versions into one ICO file, so you only need one. Use a square image for the best result.
Will I lose quality converting to ICO?
No. ICO is lossless, so the converted image keeps every pixel of the original.
Does it work on iPhone and Android?
Yes. It works in Safari, Chrome, Firefox and Edge on phones, tablets and computers. Nothing to install.
