How it works
Convert a PNG into one ICO file containing 16, 32 and 48 pixel icons. Choose your image and check the centered square crop. Create the icon, download the output and copy the installation code into your site’s HTML head.
Example
logo.png → favicon.ico (16 × 16, 32 × 32, 48 × 48 px)
When to use this tool
Supply a real multi-size ICO when a site or application requests favicon.ico.
Supported formats & limits
Color calculations use opaque sRGB. Favicons accept JPG, PNG, WebP and browser-decodable AVIF up to 20 MiB and 24 MP (6 MP on lower-memory devices). PNG to ICO accepts PNG only; square icons use a centered crop.

What happens when I change the input?
An edited input needs a new result. Run the action again; previous download links are removed so you cannot mistake an old output for the current one.
Are my files uploaded?
Your files and pasted content are processed in temporary browser memory and are not uploaded for processing. App preferences store only tool IDs, language and theme. There are no accounts, ads or automatic error reports. Closing the page discards your workspace; download results you want to keep. Production pages use Google Analytics for visit statistics; see the Privacy page for details.
