What is a MP3 file?
MP3 is the most compatible audio format in existence. Every phone, car stereo, browser and editor plays it, and 128 to 320 kbps gives small files that sound good for music and speech. It is a lossy format best suited to music libraries, podcasts and maximum compatibility. The main drawback is that it is lossy, so re-encoding repeatedly reduces quality.
Frequently asked questions
Will the WAV lose quality?
WAV is lossless, so the conversion keeps every pixel or sample that is in your MP3 file. It cannot bring back detail that MP3 compression already removed, and the WAV file will usually be larger.
Will the WAV be smaller than the MP3?
No, usually larger: a minute of audio takes about 1.4 MB as MP3 and about 10.6 MB as WAV. WAV is lossless, so its size depends on the audio rather than a bitrate setting.
