MP4 to MP3 Converter

Turn your session recordings into MP3 audio. Drop in the video files and get an MP3 of each one.

Nothing uploads. The conversion runs on your own computer, so speaker and member content stays with you.

  • A whole conference at once. Drag in as many recordings as you have. Each one becomes its own MP3 with the same file name.
  • Private by design. No upload, no account, and no email address required.
  • Works offline once installed. It opens like any other app on your computer, no internet needed.

How It Works

Drop, wait, download

There are no settings to learn. If you can drag a file, you can use it.

01

Drop in your recordings As many as you like

Drag your MP4 files onto the page, or click to browse. Add more any time, even while a batch is running. Files convert one at a time, in order.

02

Watch the progress

Each file shows how far along it is and about how long is left. If a file has a problem, it tells you why in plain language and the rest of the batch carries on.

03

Save your MP3s

Download them one by one or all at once. Or pick a folder first, and every finished MP3 lands there on its own.

What Planners Use It For
  • Posting session audio for members who could not attend.
  • Sending recordings out for transcripts or captions.
  • Turning a large video file into audio that is a fraction of the size.

Your recordings never leave your computer. There is no upload, so there is nothing for anyone else to see.

Most free converters online work by sending your file to someone else's server. That is a strange thing to do with a keynote your speaker has not released, or a members-only session. This one does the work on your own machine.

We count how many people visit, install and convert, so we know if the tool is useful. We never see your files, their names or their contents.

Why Is It Free?

The same reason our service is

We built it for our own recordings and figured planners could use it too.

No cost to the planner. We say so up front.

Your AV Department is independent AV production sourcing and advocacy for association and corporate meeting planners. We scope your show, bid it to production partners, negotiate, and stay with you through load-out. We are paid by the production partner you choose.
