JPEG XL to ICO Converter

Convert JPEG XL files to ICO. Batch, free and without uploading.

This tool converts JPEG XL files to ICO. JPEG XL is a newer format designed to replace JPEG. It is very efficient in both lossy and lossless modes; browser support is still limited.

ICO is the format for Windows icons and website favicons. It holds the same icon at several sizes, such as 16, 32, 48 and 256 pixels, in one file. The tool packs every icon size from 16 to 256 pixels into a single ICO file. Use a square image for the best result.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your JPEG XL files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Optionally set a maximum width and height.
3. Press "Convert" and download the ICO files one by one or as a ZIP.

Are my files uploaded anywhere?

No. Your JPEG XL files are converted to ICO inside your browser and never sent to a server.
