How to convert ICO to AVIF?

Converting a folder with ICO files to AVIF is also supported: simply paste or drag and drop it.

Alternatively, you can use the search field to quickly find the format you need, whether it's AVIF or something else.
Download your AVIF files, after MConverter has finished processing them
There's an option to automatically download the converted AVIF files, so you don't have to press the download icon for each AVIF. On desktop platforms, you can download the AVIF files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the AVIFs with other apps.
About the formats
Image file formats
ICO are icon files used by Windows and, often, the web. An ICO file can store one or more images in different sizes, so that they can be appropriately selected based on usage. ICO files can have a size of 256x256 pixels at most.
Image file formats
AOMedia (Alliance for Open Media)
The AV1 Image File Format (AVIF) is a new format which promises better compression and smaller file sizes than JPEG, PNG, WebP, and all other current image formats on the web. Based on the generic HEIF image format, AVIF supports alpha transparency, HDR, lossy and lossless compression. AVIF is already being used by Netflix and Microsoft.
Support in Google Chrome and Chromium-based browsers (like Microsoft Edge and Opera) has landed in late August 2020. Firefox can display AVIF images from version 93, released in October 2021. Meanwhile, Apple's Safari will support AVIF in iOS 16 (coming Fall 2022).
MConverter's AVIF encoder uses a Constant Rate Factor (CRF) of 10, so that there is no noticeable reduction in image quality while keeping the file size as small as possible.
MConverter also lets you create AVIF animations from video or GIF, up to 5 minutes long. Note that AVIF animations are currently only playable in Chrome and not Firefox.
