Which format should I choose?

MP3 for maximum compatibility. WAV when an editor or a form requires uncompressed audio. OGG for web and games. AAC for Apple devices and iPhone ringtones.

Does converting improve the quality?

No. Converting an MP3 to WAV produces a larger file but cannot recover detail that was already lost. Convert from the best source you have.

Which input formats are accepted?

MP3, WAV, OGG, AAC, FLAC and M4A up to 200 MB.

What quality does the output have?

MP3 uses high-quality variable bitrate (LAME -q:a 2), OGG uses Vorbis quality 4, AAC is encoded at 192 kbps and WAV is uncompressed 16-bit PCM.

Can I convert several files at once?

This tool converts one file at a time. Each conversion takes a few seconds once the processor has loaded.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.

Convert audio

Upload an audio file, choose the output format (MP3, WAV, OGG or AAC) and download it. FLAC and M4A files are accepted too. The conversion runs with FFmpeg in your browser, so nothing is uploaded.
