MP4 to Text: Transcribe MP4 Recordings for Free

MP4 is what your recording tools spit out, so this page is aimed squarely at those files:

• Zoom and Teams recordings - transcribe a call you recorded to text without sending the meeting to a third party
• OBS captures - turn a screen recording, stream archive, or demo into a written script
• Lecture and webinar exports - convert a class or talk into searchable notes
• Phone and camera clips - any MP4 with clear speech works

These are exactly the recordings you would not want to hand to an anonymous upload service. Because the transcription runs in your browser, a recorded internal meeting or a private lecture never touches an outside server.

A typical MP4 wraps H.264 video and AAC audio together in one container. You do not have to know or care about that - the tool inspects the file, finds the audio stream, and decodes it for you.

That means no converting the file first, no separate audio-extraction step, and no codec settings to fiddle with. Screen recorders and meeting apps that export standard MP4 all produce files this tool can read. If a particular file happens to use a codec that cannot be decoded in the browser, you get a plain explanation instead of a stuck spinner, so you are never left guessing.

A raw recording is hard to search and hard to skim. A transcript fixes both.

Once your MP4 is transcribed you can paste the text into your notes, pull out action items from a meeting, quote a passage from a lecture, or feed the content into a summarizer of your choice. Every segment carries a timestamp, so you can jump back to the exact moment in the recording where something was said.

Because you can edit the transcript in place before exporting, fixing a misheard name or a technical term takes seconds. What comes out is text you can actually use, not a rough draft you have to rebuild.

This tool loads its speech recognition engine into your browser and does all the work there. Your MP4 is read locally, its audio is decoded locally, and the transcript is generated locally.

The practical upshot: a recorded standup, a client call, an unreleased demo, or a private class stays with you. There is no server-side copy of your file and no retention policy to read, because your video is never transmitted. The single piece of network traffic is the one-time model download, cached after the first run so later transcriptions can even work offline.

You can take the transcript out in whichever shape you need:

• TXT - clean plain text for notes, docs, or search
• SRT - timed subtitles for video players and editors
• VTT - web captions for HTML5 video

SRT and VTT keep the timestamps, which is handy if you want to caption the original MP4 for accessibility or re-upload it with subtitles. All exports are generated in your browser and download directly - there is no paywall on the file and no sign-in required to get it.
