User Guide

Learn how to transcribe audio securely, improve accuracy, and export subtitles efficiently using Whisper Web.

Getting Started

Whisper Web runs purely in your browser. No account required, no upload limits, zero server-side processing.

  1. Select a Model: For most users, the default Base model offers the best balance of speed and accuracy. Switch to Tiny for slower devices.
  2. Load Your Audio: Drag and drop any .mp3, .wav, or .m4a file. We also support video files like .mp4.
  3. Transcribe: Click "Start". The first run may take a moment to load the AI model (approx 75MB) into your browser cache.

Privacy & Security

Zero Data Transfer Guarantee

Your audio files and transcripts never leave your device. All processing happens locally via WebAssembly. You can even turn off your Wi-Fi after the site loads to verify this.

Because we don't store your data, we cannot recover lost transcripts. Always ensure you export your work before closing the tab.

Optimizing Accuracy

Whisper is powerful, but input quality matters. Follow these tips to get near-perfect results:

Clear Audio
Use a directed microphone or headset.
One Speaker
Avoid overlapping dialogue.
Quiet Room
Minimize background noise/fans.
Standard Accents
Speak clearly and efficiently.

Best for notes, blogs, and articles.
