What is an AVIF file?
AVIF – AVIF image. AVIF is a newer picture format based on the AV1 video codec. It gives smaller files than JPG or WebP at the same quality and supports transparency, but it is slower to create and older software cannot open it.

ICO – Windows icon. ICO is the Windows icon format. One file holds the same picture in several sizes, each at most 256 × 256 pixels; browsers also use it for the small icon on a tab (the favicon).

- Only the first frame of the animated AVIF is converted, because ICO holds a single picture.
- Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.
Frequently asked questions
Is converting AVIF to ICO free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my AVIF pictures uploaded anywhere?
Pictures up to 200 MB never leave your device: ConvertKitty converts them inside your browser, with ImageMagick compiled to WebAssembly. Only larger files, or formats your browser cannot handle (camera RAW, PostScript, XPS, LibreOffice and Publisher files, and video or audio), are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
How large can the AVIF file be?
Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.
Can I change the size or quality of the ICO?
Yes. Click Options next to the file to set a width and height, choose a quality, remove metadata and more. Only the settings that make sense for AVIF to ICO are shown.
Can I convert several AVIF files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
