Convert PNG to ICO
How to make an ICO (favicon) from PNG?
This tool converts regular images into the ICO format, which is used for website icons (favicon.ico). The process is as straightforward as possible:
- Download the source: Drag and drop a PNG image with a transparent background into the browser window.
- Conversion: The script converts the file into icon format.
- Download: Save the finished .ico file and upload it to the root of your site.
Advantages of Client-Side generation
Creating a favicon is a technical task, and sending sources to a third-party server for the sake of a 15 KB file is pointless. We use WebAssembly to work on the fly:
- Preserve transparency: The algorithm correctly processes the alpha channel PNG so that the icon looks neat on browser tabs.
- Speed: There is no download or upload step over the network. Generation occurs instantly using the resources of your processor.
- No traces: The file is generated in the RAM of your device. It's just a tool, not cloud storage.
