Your audio never leaves your device
Free Zoom transcription, on your device
Turn a saved Zoom meeting into a transcript without uploading it to a service. It runs in your browser, so the recording stays private. Free transcription with speaker labels, no subscription, no signup.
Takes a little extra time, and your audio still never leaves your device. Labels go by how voices sound, so treat them as a best effort: one person can be split across two or three labels, similar voices can be merged, and someone joining partway through may be folded into a speaker already talking. Giving a number usually helps. Check them before relying on them.
Specifying this number improves accuracy. Count people who really take part, whenever they join. Someone who only says a word or two is better left out.
Timestamps each word instead of each phrase, so short interjections like "Yeah" go to the right person. On a busy four-person recording this corrected about 1 word in 5; it changes little when people talk in long turns. Adds roughly 40% to the time on a computer, and almost nothing on a phone.
Phone audio loses the high frequencies that separate consonants, so they are put back before transcribing. Only phone-quality recordings are treated, and you are told when it happens. Also even out volume is for one case: someone far from the microphone and much quieter throughout. It cost accuracy on other recordings, so use it only if a quiet person came out badly.
Worth filling in. The speech model knows ordinary English, not your subject, so a word it has never heard becomes whatever sounds closest, and it usually gets that word wrong every single time it comes up. A sentence is enough, and the names and jargon in it are picked out and watched for. It cannot guess a word you do not mention, so name the people and the terms that matter.
Free, no signup. The first time you use it, it takes a minute or two to set up. After that setup is quick. Works with MP3, WAV, M4A, OGG, FLAC and AMR, and long recordings are handled in parts.
Transcribe Zoom without the privacy tradeoff
Plenty of tools will transcribe a Zoom recording if you upload it to them. For an internal review, a candidate interview, a client call, or a board session, that upload is the problem rather than the solution. MeetingScribe transcribes the recording in your browser, so the audio stays on your device and no cloud copy of your meeting is created.
This also covers the common case where the meeting was recorded locally in the first place, which means Zoom never had it either. Transcribing locally keeps that property intact instead of undoing it at the last step.
Finding the right file
A local Zoom recording is not one file, it is a folder, and picking the wrong item from it is the usual first stumble. After the meeting ends, Zoom converts the raw capture and writes a folder containing several things:
- An MP4 video file, typically named zoom_0.mp4. This is what most people reach for, and it is the slowest choice because you have to extract the audio anyway.
- An M4A audio-only file, typically named audio_only.m4a. This is the one you want. It is far smaller, it loads faster, and the tool reads M4A directly.
- A playlist file and, if anyone typed during the meeting, a chat text file. Neither is useful here, though the chat log is often worth keeping alongside the transcript.
If the folder holds only a large file with an unfamiliar extension, the conversion step did not finish, which happens when Zoom or the computer was closed abruptly. Opening the Zoom app and finding the meeting in its recorded list will usually let you trigger the conversion again. Zoom's layout and file names do change between versions, so treat these as a description of the common case rather than a guarantee.
The per-participant audio trick
This is the single biggest quality improvement available, and almost nobody knows about it because it has to be enabled before the meeting.
Zoom has a recording option to save a separate audio file for each participant. With it on, a local recording produces an additional folder containing one audio file per person rather than a single mixed track. That changes the speaker problem completely: instead of relying on automatic separation to guess who is speaking, you transcribe each participant's file individually and already know, with certainty, whose words those are.
It costs you one transcription run per participant and a few minutes of interleaving the results by timestamp, which is why it is worth it for interviews, disciplinary meetings, and anything where misattributing a sentence would be a real problem, and overkill for a routine standup. Turn timestamps on when you do this, since they are what let you merge the transcripts back into the right order.
How to do it
- Open your local Zoom recording folder and find the audio-only M4A file.
- Drop it into the tool above, and turn on speaker separation if you want participant labels.
- Choose the small model if the call had poor connections, accents, or crosstalk. Remote meeting audio is compressed twice over and benefits from it.
- Transcribe on your device, then rename the speakers and correct names and jargon in the editor.
- Download the transcript as text, or SRT and VTT for captions, and use Copy notes prompt to draft minutes.
If all you have is the video, exporting the audio track first is the same short detour it is for captions.

Frequently asked questions
- Which Zoom file do I use?
- The audio-only file, usually named audio_only.m4a, saved alongside the video in your local recording folder. Drop that into the tool. If you only have the video, extract or export its audio track first and use that instead.
- Where does Zoom save local recordings?
- By default, in a Zoom folder inside your Documents folder, with a subfolder per meeting named by date and topic. You can also open the Zoom app's recording settings to see and change the exact location, or find a past recording in the Recorded tab of the meetings list.
- Does Zoom not transcribe recordings itself?
- Zoom's own automated transcript applies to cloud recordings and what you get depends on your plan and account settings, so check your own account. It also means the recording sits in Zoom's cloud. If you recorded locally, or you would rather the meeting audio stayed on your machine, transcribing it yourself avoids both issues.
- Can I get who said what?
- Yes. Turn on speaker separation and rename the speakers. If you enabled Zoom's per-participant audio option before recording, you can do even better: see the section on that below.
