Audio Converter — MP3, WAV, M4A, OGG, FLAC
Convert audio between MP3, WAV, M4A, OGG and FLAC with control over bitrate, sample rate and channels. Convert a whole batch at once in your browser, with nothing uploaded and no limit on downloads.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
How it works
Drop one or many audio files, choose the format and quality, and press Convert. Video files work too: their sound is extracted. Download each result on its own or all of them as a ZIP.
Which format should I choose?
MP3 and M4A are small and play almost everywhere. WAV is uncompressed and ideal for editing. FLAC is lossless but smaller than WAV. OGG uses the efficient Opus codec, which is popular on the web and in games.
FAQ
Does converting to WAV or FLAC improve quality?
No. They keep exactly what is in the source, but they cannot restore detail an MP3 has already lost.
Which MP3 bitrate should I use?
192 kbps is a good default for music, 128 kbps is fine for speech, and 320 kbps is the highest MP3 quality.
Are my files uploaded?
No. Conversion happens inside this browser tab.
What can you do with an audio converter?
Editors turn phone recordings into WAV files that every timeline accepts; podcasters export a small MP3 from a large master; musicians archive takes as lossless FLAC; and anyone stuck with a file a device refuses to play can switch it to a format that works everywhere.
