About the Audio Converter
Our free online Audio Converter transcodes an audio file between major formats — WAV, MP3, and OGG. It's useful for converting a high-quality WAV recording into a portable MP3 for sharing, or converting an audio track into the specific format a device or platform requires.
Unlike most online tools, transcoding happens entirely inside your browser using the Web Audio API — your audio file is never uploaded to a server. That means it's fast, works without an internet round-trip, and keeps your files completely private and secure.

Step 2

Frequently Asked Questions
Which audio formats are supported?
You can convert between major audio containers including MP3, WAV, OGG, and M4A — upload any of these as your source file and choose WAV, MP3, or OGG as your target output format.
Is my audio uploaded to a server?
No. All decoding, transcoding, and container formatting are executed locally inside your web browser using the Web Audio API — your audio file never leaves your device.
Which format should I choose?
Choose WAV for lossless, uncompressed audio best suited for editing. Choose MP3 for the smallest, most widely compatible file size. Choose OGG for an efficient, open-format alternative to MP3.
Will the audio quality change?
Converting to WAV is lossless. Converting to MP3 or OGG uses standard lossy compression, similar to how most commercial music files are encoded, with minimal perceptible quality loss at default settings.
Does it cost money?
No. The Audio Converter is 100% free to use, with no registration or account required.
