Why convert WAV to FLAC?
You have a WAV file that will not open on one of your devices or applications. FLAC is more widely supported for your use case: CD archiving, audiophiles, Bandcamp, Qobuz.
How to do it, step by step
- Drop your WAV fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: FLAC is already selected. FLAC is a lossless format: there is no quality setting, the sound is reproduced identically. The file will be noticeably larger than a compressed format.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your FLAC, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The WAV format (Waveform Audio File Format)
WAV is an uncompressed format: it stores raw audio, exactly like a CD. The quality is perfect but the files are large (about 10 MB per minute at CD quality). It is the reference format for audio editing, music production, transcription and professional software.
- No quality loss
- Read by every audio application
- Ideal for editing and transcription
- Very large files
- No standardized metadata (title, artist)
The FLAC format (Free Lossless Audio Codec)
FLAC compresses audio with zero loss: the file is 40 to 60% the size of the original WAV but reproduces exactly the same sound. It is the format of choice for audiophiles and music archives. It is free, open, and supports metadata and cover art.
- Quality identical to the original
- Free and open format
- Supports tags and cover art
- Files 5 to 10 times larger than an MP3
- Not played by Apple devices without a third-party app
