    Frequently asked questions

    Is converting ICO to BMP free?

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

    What happens to a transparent background?

    BMP has no transparency, so transparent areas are filled with white. You can choose black or any other colour in the settings.

    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.
