Local Audio & Video Transcription

Quick answer

Local Audio & Video Transcription is free and runs entirely in your web browser at https://aimstudio.co.in/freetools/transcribe — your file is processed on your own device and is never uploaded to a server. There is no sign-up, no watermark and no file-size cap imposed by us; the practical limit is your device's memory. It works in Chrome, Edge, Firefox and Safari on Windows, macOS, Linux, iOS and Android.

Speech-to-text powered by OpenAI Whisper, executed on your own device through Transformers.js and ONNX Runtime WebAssembly. Choose tiny, base, or small; the model file downloads once and is cached by your browser.

Transcription that runs offline, on your machine

Almost every free transcription service uploads your recording, processes it on their infrastructure, and keeps it for some period described in a privacy policy. For an interview, a therapy session, a medical consultation or a confidential meeting, that is the whole problem.

This runs a speech recognition model inside your browser using WebAssembly. The model is fetched once and cached; after that the page works with no network connection at all. Your audio is never transmitted, because there is nothing on the other end to transmit it to.

The first run downloads a model

Speech recognition needs model weights, and they are large — this is the one genuine cost of doing it locally. The first transcription pauses while those weights are fetched, then they stay in browser storage and subsequent runs start immediately.

A smaller model transcribes faster and uses less memory; a larger one handles accents, background noise and technical vocabulary noticeably better. If a transcript comes out garbled, the model size is usually the thing to change first.

What it is good at, and what it is not

Clear single-speaker audio — a lecture, a voice memo, a podcast — transcribes well. Accuracy falls with heavy background noise, several people talking over each other, or very strong accents in a small model.

It does not label who is speaking. A two-person interview produces one continuous transcript rather than an alternating dialogue, so expect to do that pass yourself.

This tool runs entirely inside your browser. The file you select is read into local memory, processed on your own device, and never sent to a server.

Available free in the United Kingdom, United States, Ireland, Canada, Australia and across the EU. Because files are processed in your own browser and never uploaded, no personal data crosses a border, which keeps use consistent with UK GDPR, EU GDPR and CCPA/CPRA expectations.

Frequently asked questions

Is my audio recording uploaded anywhere?

No. Your audio is decoded and fed to the model inside your own browser tab. The only network request is the one-time download of the Whisper model weights, which travels the other way.
