ICO is the Windows-specific format used for application icons, file type icons, and website favicons, bundling multiple sizes of the same image into a single file. AVIF graphics, especially simple logos exported in AVIF for web use, can work reasonably well as an icon source since the format supports transparency the same way PNG does, letting any transparent background carry through cleanly into the resulting icon.
The conversion process simply needs to decode the AVIF content and package it into the ICO container Windows expects, generating the standard size variants icons typically include.
- Install Batchify Image Converter and Resizer Pro on your Windows PC.

- Click Convert. ICO files are written to the output folder, fully offline.
- 100% offline — your images are never uploaded anywhere
- Bulk conversion of entire folders, including sub-folders, in one click
- Preserves transparency from AVIF's alpha channel in the resulting icon
- Produces standard Windows ICO files for icons and favicons
- Multi-core processing for fast handling of large batches
- Option to delete original AVIF files automatically after conversion
