Supported video and audio formats

You can pull the audio out of almost any video: MP4, MOV, MKV, AVI, WebM, FLV, WMV, M4V and 3GP files all work. Just drop in your clip and Sondra reads the sound track from it.

For the output you can choose MP3 for the smallest, most compatible file, AAC for great quality at a small size, or WAV and FLAC when you want lossless audio with no quality loss. Common jobs like MP4 to MP3, MOV to MP3 and MKV to WAV all take just a few seconds.

How to convert video to audio (MP4 to MP3 and more)

Maybe you want to turn a music video into an MP3, save the audio from an interview, or keep a podcast recording that came as a video file. Sondra pulls the audio out in a few seconds. Upload your video, choose MP3 (the format that plays everywhere), and download. No account, and nothing is sent to a server.

MP4 to MP3 is the most common job, but Sondra also handles MOV, MKV, WebM and AVI. Pick WAV or FLAC when you want lossless audio, or AAC and Opus when you want the smallest file at good quality. Everything runs in your browser with FFmpeg, so your video never leaves your device.

Because the audio is extracted in your browser, nothing is uploaded and there is no queue. It works on any device with a modern browser, including phones and tablets.
