How to Choose the Right Audio Output Format
Pick MP3 or WAV based on the next job your audio file needs to do.
Start with the destination
The best audio format depends on where the file goes next. A file for messaging, playback, or publishing has different needs from a file for editing or archiving.
Choose MP3 for convenience
MP3 is compact and broadly supported. It is a good default for quick sharing, notes, exported speech, and files that need to open almost anywhere.
Choose WAV for production
WAV is better when you will edit the audio after conversion. It gives audio software a straightforward uncompressed file to work with.
Keep an original copy
If the source is important, keep the original file. Conversion creates a new output, but it is not a substitute for an untouched master copy.
