Convert image files with our easy-to-use and free tool. Our tool lets you upload a AVIF (AV1 Image File Format) file and, from this, create a new image saved in the ICO (Icon) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple AVIF image files; up to 25 files at a time can be converted.
Along with converting AVIF image files to ICO, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single AVIF file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a grayscale filter to the image, turning any color image into a grayscale image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.

The AVIF format is an image-based container format designed to store images or image sequences that are compressed with the AV1 compression algorithm. The format has been around since 2019 and is based on the HEIF container format, and as such, it competes with the HEIC image format.
During tests, the format has shown to perform better than JPG files, not just in the reduced file size but in overall image quality. Support for the format is growing and is already supported in the Chrome and Firefox web browsers. AVIF files can also be opened in many 2D image editing applications.

The ICO file is an image format that started life on Microsoft Windows 1.0 and was used exclusively for storing image icons used by the operating system. Back then, ICO files were limited in size to 32x32 pixels with only two colors. With subsequent versions of Windows, the format has been amended and upgraded to support larger images with more colors.
Although the initial ICO format was not compressed due to their already small sizes (and limited computing power to decompress them in real-time), as the size of image icons has increased over the years, Microsoft recommends that for larger icon files, PNG compression be used for storing the raster data.
