# Audio converter — change format in your browser, no upload

> Convert audio between MP3, WAV, FLAC, OGG and M4A in your browser. No upload — the conversion runs on your device with FFmpeg.

Convert an audio file between MP3, WAV, FLAC, OGG, and M4A without uploading it. FFmpeg runs in your browser to do the encoding on your device.

Format conversion solves compatibility gaps: a voice memo saved as M4A that a tool wants as WAV, or a big lossless file you need as an MP3 to email. Converting on-device keeps private recordings out of the cloud.

Pick the target by purpose — MP3 or OGG for small, shareable files; WAV or FLAC when you plan to edit or want to preserve every detail. The encode runs locally through FFmpeg, so it works on whatever your browser can handle.

Trim the file first with Trim audio, level its loudness with Normalize, or, if you want a text version, run it through Transcribe.

## How to

1. **Add the audio.** Drop the file onto the tool or browse for it.
2. **Pick a target format.** Choose the output format your player or workflow needs.
3. **Convert.** Re-encode the audio locally to the chosen format.
4. **Download.** Save the converted file to your device.

## FAQ

### Should I convert to MP3 or WAV?

MP3 is small and universally playable; WAV and FLAC are lossless and better for editing or archiving where quality matters more than size.

### Does converting to MP3 lose quality?

MP3 is lossy, so some data is discarded, but a high bitrate is transparent for most listening. Converting between lossless formats keeps full quality.

### Can I convert several files at once?

Yes — add multiple files and convert them to the same target format in one session.

### Is my audio uploaded to convert it?

No. FFmpeg runs in your browser tab; the audio never leaves your device.
