Summary

How it works
- Select or drag a HEIC or HEIF image file onto the drop zone.
- The browser decodes the HEIC data using a WebAssembly-based decoder.
- The decoded image is drawn onto two Canvas elements at 32x32 and 16x16 pixels.
- Pixel data from both canvases is packed into a valid multi-size ICO binary.
- Click "Download ICO" to save the resulting favicon-ready .ico file.
Use cases
- Create a favicon from an iPhone photo without installing software.
- Convert a HEIC logo or icon export to ICO for Windows app packaging.
- Generate a quick site favicon from any HEIC image on the fly.
- Produce a multi-resolution ICO file from a HEIF camera shot.
- Prepare an icon for Electron or desktop app projects.
- Batch-preview HEIC images before choosing which one to use as an icon.
