MP3

MP3 is widely supported and usually much smaller than WAV. It uses lossy compression, so some detail is discarded. It is a strong default for sharing, uploads, and everyday playback.

WAV

WAV commonly stores uncompressed PCM audio. Files are large but easy for many editors to open. Converting a lossy MP3 into WAV does not restore lost detail—it only changes the container and encoding of the same information.

FLAC

FLAC is a lossless compressed format. It usually uses less space than WAV while preserving the decoded audio information from a lossless source. Recipients need FLAC support, which is common in many modern players but not universal on every form or device.

What the Audio Format Converter outputs

The converter can export MP3, WAV, or FLAC from supported inputs (MP3, WAV, FLAC, M4A, AAC, OGG) within the 25 MB limit. Pick MP3 for sharing, WAV for uncompressed editor workflows, and FLAC for lossless archiving when the recipient supports it.
