Click on “Choose file” and then select an input file of the correct format (and extension). Clicking on “Convert” uploads and converts the file. The output file is automatically downloaded, along with a log file if this option is ticked.
{% if not service_mode or logged_in %} You may upload archives of files of the same type. Archives of types .tar, .tar.gz, .tar.xz, and .tar.bz are supported. {% else %} If you wish to convert a batch of multiple files of the same type contained within an archive, this functionality is available to logged in users. Use the “Log in” link in the header to log in or register, then return to this page. A higher file size limit is also available to logged-in users (except for conversions with Open Babel, due to a bug in it when converting large files). {% endif %}
If any issues are encountered (e.g., the output file does not download), please click on “Provide Feedback” in the navigation bar.
