Meetings, audio only
Microsoft Teams recording to MP3
Strip the video off a Microsoft Teams recording and keep a small, listenable MP3 — done inside your browser, so a confidential meeting never touches anyone else's server.
The recording nobody has time to watch
A recorded meeting is one of the least useful artefacts in modern work: gigabytes of shared screens and thumbnail faces, wrapped in a video player nobody opens twice. What people actually want from it is the conversation — playable in the car, at 1.75x on a walk, or filed as a small archive that does not eat a shared drive.
Zoom does offer an audio-only file for cloud recordings, but it arrives as M4A, local recordings often skip it, and Teams and Meet give you video full stop. So the job lands on a converter — and meeting recordings are precisely the files that should not be uploaded to an anonymous site: client names, pricing, HR discussions and unreleased work all live in them.
Local extraction, no re-encode of what you do not need
The tool discards the video stream entirely and only touches the audio, which is why a long meeting converts far faster than a normal video conversion. FFmpeg runs as WebAssembly on your own processor, with thread count and memory budget chosen from what your device reports, so a laptop uses its cores and a phone stays within its limits instead of crashing halfway.
Want minutes instead of audio? The video-to-text transcriber reads the same recording on-device and exports plain text or subtitles.
Step by step
1. Find the local recording
Teams recordings live in OneDrive (Recordings folder) or SharePoint for channel meetings. Open the file and choose Download.
2. Shared with you? Ask for download access
If the recording was shared view-only, ask the organiser to allow downloads, then save the MP4 to your device and bring it here.
3. Drop the file in and pick MP3
The video track is discarded and only the audio is re-encoded, so a two-hour meeting becomes a small file in about a minute on a modern laptop.
4. Choose a bitrate that suits the use
96 kbps is plenty for a spoken meeting and keeps archives tiny. Use 192 kbps if music, a demo or a recorded webinar with production audio is involved.
Questions people ask
- Why convert a meeting recording to MP3 at all?
- Nobody rewatches a two-hour grid of faces. Audio is a tenth of the size, plays in any podcast app or car stereo, can be listened to at double speed on a commute, and is far easier to archive for compliance. Teams that record every standup usually keep audio and delete the video.
- Does this work with Teams and Google Meet recordings?
- Yes. Teams exports MP4 from Stream or OneDrive and Meet drops MP4 into Drive; both are accepted, along with MKV, MOV, WEBM and the M4A files Zoom produces for audio-only recordings.
- Are we uploading confidential meetings anywhere?
- No, and that is the point. Meeting recordings routinely contain client names, salaries, legal discussion and unreleased plans — the exact material that must not be posted to an unknown conversion service. FFmpeg runs as WebAssembly inside this tab, so the file is read from your disk and never sent over the network.
- Is there a file size limit?
- No server limit, because there is no server. The practical ceiling is your device's memory: multi-gigabyte recordings are fine on a desktop, while a phone is happier with an hour or two at a time. The tool sizes its working budget to the device it detects.
- I need the meeting as text, not audio.
- Run the file through the video-to-text tool, which transcribes locally and can export .srt with timings — useful for searchable minutes without sending the recording to a transcription vendor.
- Can I convert several recordings at once?
- Yes, queue up to 60. Each shows its own progress and you can take them individually or as one ZIP at the end.
