Audio Converter
Convert audio between MP3, WAV, OGG and FLAC formats
Audio Converter switches an audio file between MP3, WAV, OGG and FLAC in either direction, so you can go from a large lossless WAV master down to a shareable MP3, or from a lossy format up to WAV when another tool specifically requires it.

Everything you need to know about audio formats
Why do audio formats even differ?
Audio formats trade off file size, quality, and compatibility differently. MP3 is universally supported and small but lossy (some audio detail is discarded); WAV is uncompressed and lossless but large; FLAC is lossless *and* compressed, a middle ground popular with audiophiles; OGG is an open, efficient lossy format used mainly in specific software and games.
Which format should you use?
| Format | Best for |
|---|---|
| MP3 | General use — maximum compatibility, small files |
| WAV | Editing/production work, where quality loss at each step compounds |
| FLAC | Archiving music losslessly at a smaller size than WAV |
| OGG | Software or games that specifically expect it |

Frequently Asked Questions
Which formats are supported?
MP3, WAV, OGG and FLAC — convert between any of the four in either direction.
Will converting a lossy file to a lossless one improve its quality?
No — converting, say, an MP3 to WAV makes a larger file but can't restore detail the MP3 already discarded. For the best result, always convert from the highest-quality source you actually have. See our guide to audio formats for when to use each one.
Does the converted file keep the same length and content?
Yes — conversion changes the format and encoding only; the audio content and duration stay the same.
Does this tool send my audio to a server?
Yes — your file is uploaded securely, converted, and deleted from our servers within 1 hour.
Is this tool free to use?
Yes — completely free, with no signup and no watermark on the output.
