Local media, downloadable model, draft transcript

Your file, decoded audio, filename, language choice, and transcript stay in this browser tab. The page downloads only the selected pinned Whisper Tiny model from Hugging Face after you start. Access Free Tools does not receive or store the recording or transcript.

Whisper can mishear names, numbers, accents, specialist terms, overlapping voices, music, and quiet speech. It can also produce plausible words that were not spoken. Click the timestamps and check important text against the recording before you publish, quote, caption, or rely on it.

The Whisper code and model files are provided under the MIT license. Mediabunny, used to read local media in the browser, is provided under the MPL-2.0 license. Source and license links are included in the guide.

How to use the Audio and Video Transcriber

Choose one permitted audio or video file up to 250 MB and 60 minutes. The browser checks its container and audio tracks before downloading a model.

Frequently asked questions

Plain-language answers about supported media, browser decoding, model downloads, partial transcripts, caption exports, privacy, permission, and accuracy limits.

Does the transcriber upload my audio or video?

No. The selected file, decoded audio, transcript, filename, and language choice stay in this browser tab. They are not uploaded to Access Free Tools. The pinned model files download from Hugging Face only after you start transcription.

Which audio and video files can I transcribe?

The tool can inspect MP3, WAV, M4A or AAC, FLAC, OGG or Opus, MP4, MOV, WebM, and MKV containers. The audio codec inside the file must also be decodable by your current browser. An unsupported codec is rejected before the model download.

What do the main Audio and Video Transcriber inputs mean?

Choose the local recording, then select its dialogue audio track when several tracks are present. English uses the smaller English model; Auto or a named non-English language uses the multilingual model. WebAssembly is the compatibility choice, while WebGPU is an optional beta path on supported devices.

What are the file and recording limits?

The beta accepts one file up to 250 MB and 60 minutes. Desktop is recommended above 15 minutes because decoding and speech recognition use device memory and processor time.

Which model does the browser transcriber use?

English uses the pinned onnx-community Whisper Tiny English timestamped model. Auto and named non-English choices use the pinned multilingual timestamped model. Both use quantized browser files and run through Transformers.js.

How should I read the Audio and Video Transcriber result?

Treat the timestamped text as an editable first draft, not a certified transcript. Click a timestamp to compare each important section with the local recording before copying or exporting it.

What should I double-check before trusting the Audio and Video Transcriber transcript?

Check names, numbers, dates, accents, technical terms, overlapping voices, quiet speech, music, and noisy sections. Whisper can mishear speech or produce plausible words that were not spoken.

Can I edit and download a partial transcript?

Yes. Each completed five-minute section appears immediately. If you stop the job or a later section fails, completed caption segments stay available for editing, copying, and TXT, SRT, or WebVTT download.

What is the difference between SRT and WebVTT?

Both store timed captions. SRT is widely accepted by editors and video platforms. WebVTT is designed for web video and starts with a WEBVTT header. TXT contains the words without caption timing syntax.

Why does the tool offer WebAssembly and WebGPU?

The q8 WebAssembly path is the dependable compatibility choice. WebGPU can be faster on a supported device but remains experimental for this workload, so the tool detects an adapter, labels the option as beta, and can fall back to WebAssembly.

Can this tool identify different speakers?

No. Version one does not provide speaker identification or diarization. It also does not translate, record a microphone, import URLs, process batches, or render captions back into a video.

What happens when I reset or close the page?

The browser revokes the local media URL and terminates its workers. The transcript is not stored by Access Free Tools, so download the files you want before resetting, refreshing, or closing the tab.
