Tools / AVIF to ICO Converter

AVIF to ICO Converter

Convert AVIF files to ICO. Batch, free and without uploading.

This tool converts AVIF files to ICO. AVIF is a next-generation image format based on AV1 video coding. It usually beats even WEBP on size, but older programs may not open it.

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 AVIF 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.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

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