Drop a video or audio file, or choose one. 4. Read, edit, copy or export the result. 🔒 Audio transcription that never leaves your computer Online sites upload your recording to a server.

Transcribe MP4 or transcribe MP3 files the same way: it is an mp3 to transcript tool as much as a video to transcript app for video transcription. 🎙 Who uses this audio to transcript tool Journalists and researchers use it for interview transcription without sending a word anywhere. Podcasters turn an episode into a podcast transcript for the show notes. Teams use it for meeting transcription: Zoom saves recordings as MP4, so Zoom transcription takes one drop. ⏱ Transcription with timestamps, and subtitles Timestamping transcription is built in: every segment carries its start time, and a click plays the recording from there. Need subtitles? Export SRT or VTT and the cues are ready for your editor or player, like a subtitle generator that keeps your file at home. Video to SRT and audio to SRT take the same click. ✍ Edit and correct 🔹 Click any line to fix a name 🔹 Find and replace in one go 🔹 Play back slower or faster 🔹 Copy all, or copy with timestamps 🔹 Switch to paragraphs for reading 📊 How accurate and how fast The model is Whisper large-v3-turbo, so this is AI transcription you can check line by line. We measured it on six kinds of English recordings: narration and noisy speech, an earnings call and a meeting, a podcast and accented speech. ◆ Words wrong on average: 8.6% ◆ Desktop Whisper on the same files: 7.8% ◆ Clean narration: about 2% ◆ Laptop with Intel Iris Xe graphics: 0.3 to 0.6 s of work per second of audio 🔁 Made for long recordings Close the tab halfway, reopen the file later, and MP4 to Transcript resumes where it stopped. After a graphics driver reset, it reloads the model and carries on. 💻 Transcription software in your browser It needs Chrome 121 or newer with WebGPU, as on Windows, macOS and ChromeOS. It works like Whisper Web, as an extension: Whisper transcription of your own files, with mp3 transcription and mp4 transcription in one place. 🎯 Open the mp4 to transcript page the next time a recording needs writing down. If something goes wrong, the link under your history reaches us. ❓ Is MP4 to Transcript free? 💡 Yes. You can transcribe audio to text free, with no account, no minute limits and no watermark. ❓ Does it upload my audio or video? 💡 No. Your audio, video and results stay on your computer. The only download is the speech model, once, from Hugging Face: 566 MB, or 0.76 GB on some graphics chips. ❓ Which languages does it understand? 💡 99 of them, from English to Swahili. It detects the language, or you pick it. Accuracy varies: highest in widely spoken languages, lower in rarer ones, where picking the language by hand helps. ❓ Can it turn a voice memo into text? 💡 Yes. Voice memo transcription works with the M4A files phones save, so M4A to text, or any voice recording to transcript, is one drop. It is speech to text for recorded files, not live voice to text. ❓ Can it transcribe video to text with speaker names? 💡 It writes what is said, with timestamps, as one stream. It doesn't tell speakers apart. ❓ How long does a file take? 💡 It depends on the graphics chip Chrome uses: on an Intel Iris Xe laptop, a 30-minute file takes about 9 to 18 minutes, plus up to a minute to load the model. ✨ MP4 to Transcript: private, timestamped and in your browser
