Are you familiar with the situation when you urgently need to convert audio for a podcast, presentation or video, but online converters require you to upload gigabyte files to some unknown servers, risking your privacy?

You can adjust the parameters before running, listen to the result before downloading and instantly save the finished file. Also available is the unusual ability to quickly export without file size limits.
