Engines and licensesAbout Audio Converter
The audio converter changes a file's format so it plays wherever you need it: on your phone, in the car, in an editing program or in your personal archive. Upload the audio, choose the target format and quality, and download the new file. The conversion is done by FFmpeg inside your browser: the file is never uploaded to a server.
What you can do with it
- 01
Music for any player
Turn the FLAC or WAV files your car, phone or player can't read into MP3s — they'll take up much less space too.
- 02
Phone recordings to MP3
Convert voice notes and recordings in M4A, OPUS or WEBM to MP3 to share them or edit them in any program.
- 03
Prep audio for editing
If you're cutting a video or producing a track, convert the MP3 to WAV and work with an uncompressed format every editor accepts.
- 04
Archive without losing anything
Convert your WAV recordings to FLAC to store them in less space without giving up a single detail of the original sound.
How it works, in 3 steps
Upload the file
Drop the audio into the panel or browse for it: MP3, WAV, FLAC, OGG, M4A, AAC, OPUS or WEBM.
Choose the target format
MP3 to listen and share, WAV or FLAC to edit or archive, OGG or M4A for more specific uses. In the advanced settings you pick quality, sample rate and channels.
Convert and download
Click «Convert» and download the result. If you have more files, repeat with each one.
Which format to choose
MP3
The all-rounder: plays on any device and is small. You pick the quality: 128, 192, 256 or 320 kbps.
WAV
Uncompressed audio. Large, but the easiest to edit, mix or master.
FLAC
Lossless compression: the sound is identical to the original and the file is much smaller than a WAV.
M4A (AAC)
Lossy compression more efficient than MP3, very common on Apple devices and phones.
OGG
An open format with lossy compression, widely used in video games and web projects.
Sample rate and channels
Keep the originals or set 44.1 or 48 kHz and switch to mono or stereo, depending on what the destination needs.
Tips for better results
- Always keep an original in WAV or FLAC and convert from it, never from already compressed copies.
- Converting an MP3 to WAV or FLAC doesn't bring back lost quality: you just get a bigger file with the same sound.
- To send audio by message or email, a 128 or 192 kbps MP3 is the lightest option.
- If you'll keep editing, work in WAV and leave compression for the final export.
Frequently asked questions
Which formats can I convert between?
You can upload MP3, WAV, FLAC, OGG, M4A, AAC, OPUS or WEBM and convert to MP3, WAV, FLAC, OGG or M4A.
Do I lose quality when converting?
It depends on the direction. From lossless (WAV, FLAC) to compressed (MP3, M4A, OGG) there's a small, usually inaudible loss. Between lossless formats, the sound doesn't change. And from compressed to lossless nothing is recovered.
Which MP3 quality should I choose?
192 kbps is a good balance for almost everything; 320 kbps is the format's highest and hard to tell from the original. For speech, 128 kbps is usually enough.
Is my file uploaded to the internet?
No. Conversion happens in your browser with FFmpeg compiled to WebAssembly; the file never leaves your device.
Can I convert several files at once?
The converter works on one file at a time; if you have several, convert them one after another. If you want to combine them into a single audio, use Audio Joiner.
Why is the converted file bigger than the original?
It happens when going from a compressed format to WAV or FLAC: the audio is stored without lossy compression and the file grows, even though the sound is the same.
