One format that plays everywhere
MP3 is the most widely supported audio format in the world — every phone, browser, car stereo and media player handles it. If you have a file in WAV, M4A/AAC, OGG or FLAC that something refuses to play, converting it to MP3 is the simplest fix.
This converter uses the Audio Optimizer engine and runs completely in your browser, so your file is never uploaded. Whatever your browser can decode, you can turn into an MP3 — and you control the bitrate, so you decide the balance between quality and size.
Pick 192 kbps for near-transparent music, 128 kbps for everyday web use, or mono at 64–96 kbps for speech. You can also trim the clip first so you only export the part you need.
Step by step
- Drop your audio file (WAV, M4A, OGG, FLAC or MP3) onto the upload area.
- The format is set to MP3 — choose a bitrate that suits your content.
- Optionally trim with the waveform handles or switch to mono.
- Watch the live estimated size update as you adjust.
- Click Optimize & download to save the MP3.
Tips
- If a file will not play on an old device, converting to MP3 almost always solves it.
- FLAC and WAV are lossless and large — MP3 makes them dramatically smaller for sharing.
- M4A/AAC files from phones convert cleanly to MP3 for wider compatibility.
- Trim before exporting to drop unwanted intros, outros or silence.
- Keep your original if it is lossless and you might edit again; use MP3 as the shareable copy.
