Pull the audio out of a video file and save it as an MP3 — useful for lectures, interviews, podcasts and voice recordings you were sent as video.
The video is decoded in your browser and the audio re-encoded to MP3, so the file never leaves your device. That matters for recordings of meetings and consultations.
Longer videos take longer to process, and very large files are limited by your device’s available memory rather than by any server quota.

Not for: Very long recordings on a phone — browser memory limits the size; a desktop handles large files better.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Does the video quality matter for the audio?
Only the audio track is used. A low-resolution video with clear audio produces exactly the same MP3 as a high-resolution one.
Can I transcribe the audio afterwards?
Yes — the audio tools can turn a recording into a speaker-labelled transcript, including Arabic, English and mixed conversations.
