Which audio converter do you need?
Changing a file’s format, making it smaller and converting a whole folder are three different jobs. Pick yours below, and your audio stays on your device.
- Convert audioMP3, WAV, FLAC or M4A, from any audio or video file
- Compress audioMake an audio file smaller to send or store
- Batch audio converterConvert up to 20 files at once, to one format
Which tool fits my job?
- To turn a file into another format, such as FLAC into MP3, use the audio converter.
- To shrink one recording so it fits an email or a phone, use compress audio.
- To convert many files with the same setting, use the batch audio converter.
Is any of my audio uploaded?
Not at all. All three tools run in your browser, on your own device. Nothing is sent to a server, and there is no signup.
Which files can they open?
They read WAV, MP3, FLAC, M4A and AAC, OGG and Opus files. On desktop browsers they also read the soundtrack of an MP4, MOV, WebM or 3GP video. WMA, AIFF, AMR and AC3 files cannot be opened, and the page tells you so. Every result is 44.1 kHz.
Which formats can I save?
MP3, WAV and FLAC work in every browser. M4A and the iPhone ringtone format, M4R, appear where your browser can encode AAC. When you compress, the percentage saved is measured from the finished file, never guessed.
How is a batch different from one file?
A batch holds up to 20 files and 1 GB in all, with one setting for every file. The files are converted one after another, and you can download the results together as a ZIP. For a single file, the converter on its own is simpler.
Can I edit the audio first?
Yes. Cut out the part you want or merge several tracks first, then convert the result without picking the file again.
