Transparent favicon.ico
WebP alpha is rendered through Canvas and stored as PNG image data inside the ICO file.
Multi-size icon entries
Include classic 16, 32, and 48 px favicon sizes plus a 256 px Windows icon entry.
No server conversion
The default path uses browser WebP decoding, Canvas rendering, and a small first-party ICO writer.

- Input
- One local WebP image plus selected icon sizes and crop/background choices.
- Output
- A downloadable .ico containing the requested raster sizes.
- Real limitations
- ICO output is raster-only, very detailed art loses clarity at small sizes, and browser/favicon caches may delay visible changes.
- Privacy and data handling
- one local WebP image plus selected icon sizes and crop/background choices is processed in this browser tab. Convertr does not receive or store it; closing or reloading the page clears the working state unless the tool explicitly offers a local download.
How to use this tool
- Provide one local WebP image plus selected icon sizes and crop/background choices in the tool controls.
- Choose the settings that affect a downloadable .ico containing the requested raster sizes, then run the tool.
- Review a downloadable .ico containing the requested raster sizes before copying or downloading it.
Common failure modes
An invalid WebP, unsupported decode, empty size selection, or image too large for device memory prevents conversion.
Useful example
