    Frequently asked questions

    Is converting AVIF to ICO free?

    Yes, completely free. No account, no daily limit, no watermark and no queue.

    Does converting to ICO improve quality?

    No. ICO keeps the current picture exactly but cannot restore detail lost when the AVIF was saved. The benefit is that further edits will not degrade it any more.

    Are animated images converted too?

    Only the first frame is converted to ICO. To keep the animation, convert to MP4 or WEBM.

    Does it work on a phone?

    Yes. It works on iPhone, iPad and Android, with no app to install.

    Is there a file size limit?

    There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
