MP3 · WAV · OGG · M4A · FLAC supported
🔒 All processing runs in your browser — files are never uploaded to a server.
🔄 Why so many audio formats?
MP3 is the most universally compatible and small, so it's used everywhere. WAV is lossless, good for editing and archiving. M4A (AAC) is the default on iPhones and Apple devices. FLAC compresses losslessly, shrinking file size with no quality loss.
🎯 When to use this
- Converting a format a device or app doesn't support into one it can play
- Turning a large WAV original into a smaller MP3 for sharing
- Converting a compressed file to FLAC for lossless archiving
🔒 Your audio is never uploaded
Conversion runs using a conversion engine (ffmpeg) downloaded into your browser. Your file is never sent anywhere, so personal recordings are safe to convert too.
🎵 Format comparison
The right format depends on where the audio will be used.
| Format | Compression | Notes & best use |
|---|---|---|
| MP3 | Lossy | Best compatibility — plays on any device or app |
| WAV | None | Raw audio — for editing and masters; large files |
| M4A / AAC | Lossy | Better quality than MP3 at the same bitrate — Apple standard |
| OGG | Lossy | Open format — common in games and web dev |
| FLAC | Lossless | Smaller than WAV while preserving the source — for archiving |

💬 Frequently Asked Questions
- What formats are supported?
- Input can be most audio formats your browser can play; output can be chosen from MP3, WAV, OGG, M4A, or FLAC.
- Does converting reduce quality?
- Converting to a lossless format like WAV or FLAC loses no quality. Converting to a lossy format like MP3, OGG, or M4A can lose a little quality (a bitrate that sounds fine for everyday listening is used by default).
- Is the converted file stored anywhere?
- No. Conversion happens only in your browser's memory, and nothing remains on any server after you download the result.
- Does conversion degrade the audio?
- Lossless-to-lossless (WAV, FLAC) keeps quality intact. Converting to lossy formats like MP3 or M4A can reduce it.
- How do I make a ringtone?
- Convert to MP3 or M4A first, then cut the section you need with the audio cutter tool.
