Questions about the MP3 format

How do I open a MP3 file?

Usually a double click is enough: operating systems and the most common programs recognise it. If the program or website you use won’t accept it, you can convert it here to a more common format, for example WAV.

What extension do MP3 files have?

.mp3. The MIME type is audio/mpeg.

Does converting a MP3 lose quality?

It depends on the target format: to lossless formats (PNG, FLAC, WAV) nothing is lost; to compressed formats (JPG, MP3, MP4) you can choose the quality to balance size and result.
