Transcribe a Zoom Recording or Meeting, Free and Private

Find the Zoom recording file you should transcribe

Where the file lives depends on whether the meeting was recorded to your computer or to the Zoom cloud. Menu labels move between Zoom versions, so treat these as landmarks rather than exact click paths.

• Local recordings: the desktop app saves them by default to a Zoom folder inside Documents on both Windows and Mac, with one subfolder per meeting named by date, time and topic. Zoom converts the files after the meeting ends, so let that progress bar finish before you open anything.
• Which file: inside that folder you will typically find an MP4 with video and an M4A with audio only. Transcribe the M4A. A one-hour M4A is often only a few dozen megabytes, while the matching MP4 can run to several hundred.
• Cloud recordings: on paid plans, recordings appear in the Recordings area of the Zoom web portal. The host can download the MP4 and, depending on account settings, a separate audio-only file.
• Moved folder: if someone changed the save location, the Recordings list in the desktop app has an option to open the folder directly.

If only an MP4 exists and AI Studio reports that it cannot decode it, run it through GrabCast Audio Converter to extract a mono 64 kbps M4A or MP3, then transcribe that smaller file.

How to transcribe a Zoom meeting in AI Studio

AI Studio loads a Whisper model once, caches it in your browser and then processes audio on your own processor or graphics chip. Four models are offered, and the right one depends on your hardware more than on the meeting.

• Tiny, about 80 MB: the quick option for older laptops or a first rough pass.
• Base, about 210 MB: the default and a sensible choice for most clear, single-language meetings.
• Small, about 300 MB: noticeably better with accents, jargon and product names.
• Large-v3 Turbo, about 560 MB: the most accurate, but it needs WebGPU with 16-bit float support, which in practice means a recent Chrome or Edge on a modern graphics chip.

Set the spoken language if you know it; auto-detect is usually fine but can guess wrong on a call that opens with small talk in another language. Long files are cut into pieces of roughly 60 seconds at the quietest moment near each boundary, so words are not chopped in half. While it runs you see a live transcript and an estimate of the time remaining. When it finishes you can copy the text or download plain text, SRT or VTT captions, text with [mm:ss] timestamps, or a Word document.

Zoom's built-in transcripts versus a Whisper transcript

Zoom has its own speech features, and it is worth knowing what they cover before you run anything else. Availability depends on your plan and on what your account admin has switched on, so check your own settings.

• Automated captions can be turned on during a live meeting, and hosts may allow participants to save the caption text afterward.
• Audio transcripts for cloud recordings are available on eligible paid plans. They appear next to the recording in the web portal and usually include speaker names from the Zoom display names.
• Local recordings do not get a Zoom cloud transcript, which is the most common reason people look for another way to transcribe a Zoom meeting.
• AI summaries from Zoom's assistant, where offered, are processed on Zoom's servers and follow your organization's data settings.

A practical approach: if Zoom already produced a transcript, keep it for the speaker names, and run a Whisper transcript when you need better punctuation, a Word file, subtitles for the recording, or a copy that was produced without sending audio to another service.

Consent, cleanup and meeting notes people will use

Zoom shows a recording notice, but a notice is not the same as meeting every legal requirement. This is general information, not legal advice. US federal law and most states allow recording with one party's consent, while several states, including California, Florida, Pennsylvania and Washington, generally require all parties to agree. In the EU and UK, data protection law expects a lawful basis and clear information before people are recorded or transcribed. The simple habit that covers most cases is to say at the start that the call is being recorded and transcribed, and why.

• Read the transcript once at normal speed, fixing names, figures and acronyms; Whisper has no speaker labels, so add them where who said what matters.
• Use the timestamped text file to jump back into the recording and confirm any sentence you plan to quote.
• Rename exports with the date and topic, such as 2026-03-14-client-kickoff.txt, so desktop search finds them later.
• AI Studio's Summarize and Translate buttons, and the AI Content Pack, send text to a cloud AI; skip them for confidential calls.
