Convert audio between MP3, WAV, OGG, M4A and FLAC
Change format and bitrate in one step — useful when a platform, editor, or device only accepts a specific file type.
All tools / Format Conversion
Change format and bitrate. Supports MP3, WAV, OGG, M4A, FLAC — up to 10MB. Use a preset for common jobs.
Different tools and platforms expect different audio formats — a video editor might want WAV, a podcast host might want MP3 at a specific bitrate, and an archival copy might call for lossless FLAC. This tool converts between the five most common formats in one step.
You also control bitrate for lossy formats (64–320 kbps), so you can trade file size against audio quality depending on where the file is going.
How it works
- Upload your source file (WAV, MP3, OGG, M4A or FLAC, up to 10MB).
- Choose the output format from the dropdown.
- For MP3/OGG/M4A output, set the bitrate — higher means better quality and a larger file.
- Tap Convert and download the result.
Who uses this
Podcast hosting
Convert a WAV master down to a smaller MP3 at 128–192 kbps for faster hosting and streaming.
Video editors
Convert MP3 voiceovers to WAV, since some editing software handles uncompressed audio more reliably.
Archiving
Convert a compressed file to FLAC when you want a lossless copy for long-term storage — note this won't restore quality already lost to compression.
Compatibility
Convert to whatever format a specific app, device or platform requires.
Tips for better results
- Converting an already-compressed MP3 to another lossy format (or to FLAC) does not recover detail that compression already removed — start from the highest-quality source you have.
- Use WAV or FLAC when you plan to edit the file further; use MP3 for final, distribution-ready files where size matters.
- 192 kbps MP3 is a reasonable default for spoken-word content; music generally benefits from 256–320 kbps.
What's the max file size?
10MB per file on the free tool. For larger files, try compressing first or splitting with the Cutter.
Does converting to a lossless format improve quality?
No — converting a lossy file to FLAC or WAV keeps the same quality, it just changes the container/encoding.
Can I batch-convert multiple files?
Not yet on this tool — each conversion is one file at a time.
