WebP to ICO Converter
Drop a WebP file below and get a ICO back in seconds. ICO is lossless, so nothing is lost beyond what was already baked into the WebP. No upload, no sign-up, no watermark.
Why use this tool
Why ICO?
ICO (Windows Icon) is the favicon format — browsers and Windows read it natively, and one file can bundle several sizes.
What's wrong with WebP?
WebP is compact and modern, but some older software, email clients and design tools still won't open it.
How to convert WebP to ICO
- Upload — drag your WebP file(s) onto the box, click to browse, or paste from the clipboard.
- Adjust — pick the output format if you change your mind, and set the quality or icon sizes.
- Download — grab each ICO individually, or all of them at once as a ZIP.
Frequently asked questions
Will I lose quality converting WebP to ICO?
No. ICO is lossless — the converted image is pixel-for-pixel identical to what your browser decoded from the WebP file.
Can I convert several WebP files at once?
Yes. Drop as many files as you like — each one is converted individually and you can grab them one by one or all together as a ZIP.
Which icon sizes should I pick?
16×16, 32×32 and 48×48 (the defaults) cover browser tabs, bookmarks and Windows shortcuts. Add 64–256 px if you also need high-DPI or app-icon use.
Is this tool free?
Yes — every tool on ConvertPicto is completely free, with no account, no watermark and no file limits. The site is supported by ads.
Are my images uploaded to a server?
No. ConvertPicto runs entirely inside your browser using the Canvas API. Your files are read locally, processed on your device and never sent anywhere — we don't even have a server that could receive them.
Does it work on my phone?
Yes. The site is fully responsive and works in any modern mobile browser (Chrome, Safari, Firefox, Edge). Processing large images is naturally slower on a phone than on a laptop.
