About the formats

Extension wav
Category Audio file formats
Developed by IBM, Microsoft
Mime type audio/wav


WAV files are used for storing uncompressed audio. The WAVE format contains the waveform data for the audio track. A major difference between WAV and MP3 is that WAV files do not have compression applied, meaning that the quality is uncompromised. MP3 files use compression. As a result, WAV files are larger in size than MP3 files.
To free up space on your device, you can convert WAV files to MP3s. The slight loss in quality should not be noticeable in most cases.

FLAC, or Free Lossless Audio Codec, files contain digital audio. FLAC files utilize lossless quality, meaning that there is no loss of any original sound data. When compared to MP3 (lossy audio format), FLAC files are generally larger. Nonetheless, FLAC’s lossless compression algorithm can reduce audio by up to 70%, and still be able to reproduce the original audio afterwards. The format is royalty-free.
