Audio Converter

Convert MP3, WAV, M4A, OGG, Opus and FLAC audio to MP3 or WAV. Decoding and encoding happen in your browser, so the file is never uploaded.

Any format your browser can decode. Nothing is uploaded.

MP3 output uses the LAME encoder compiled to JavaScript, which runs in this tab. Converting an MP3 to MP3 costs one generation of quality; keep the original if you may need it later. WAV output is uncompressed 16-bit PCM written sample by sample, so it is larger but lossless.

What Is Audio Converter?

The Audio Converter turns one audio format into another without leaving the browser: it decodes MP3, WAV, M4A/AAC, OGG, Opus or FLAC, then writes a new MP3 at 128 to 320 kbps or an uncompressed 16-bit WAV. A mono downmix option halves the size of speech recordings, and the page estimates the output size before you start.

Who Uses the Audio Converter?

Podcasters and support teams convert phone recordings and voice memos into MP3 for email; anyone handed an M4A or FLAC file uses it to get a WAV for an editor that will not open the original.

How to Use the Audio Converter

  1. Drop an audio file and wait for the source player to appear.
  2. Pick MP3 at a bitrate or WAV, and tick mono for speech.
  3. Watch the progress, preview the result, then download it.

Why Choose Our Audio Converter?

  • MP3 bitrate and mono controls, so speech can be made small without a second app
  • WAV output is written from the decoded samples rather than re-recorded
  • The file never leaves the tab, which makes it safe for private voice memos
