How to Convert Ogg Vorbis Files
If you need to migrate an OGG file to something more universally acceptable like an MP3 or WAV file, there are a few easy options out there.
One of the easiest options is an online converter like FileZigZag. You don't need to download anything and you can convert multiple files at once. The downside is that you are limited to 10 conversions per day.
Another option is something like Convertio. It works entirely in your browser, but there is also a Chrome extension available for easy conversions. There seems to be no daily limit for the number of conversions, but the maximum file size is limited to 100MB.
