Play, visualize, and transcribe WhatsApp voice notes — free, private, browser-based
Type your transcription below while listening. Use keyboard shortcuts to control playback without leaving the text area.
Play WhatsApp voice notes (.opus files) directly in your browser without installing any software. Our tool supports all WhatsApp audio formats including .opus, .ogg, .m4a, .mp3, .wav, and .amr — the exact formats WhatsApp uses for voice messages on both Android and iPhone.
Features include adjustable playback speed (0.5x to 3x — perfect for long voice notes), visual waveform display, keyboard shortcuts for efficient transcription, and automatic speech-to-text using your browser's built-in recognition engine. Everything runs locally in your browser — your voice notes are never uploaded to any server.
1. Export your WhatsApp chat with media (this creates a ZIP file containing voice note .opus files). 2. Extract the ZIP and find the .opus files. 3. Upload them here. 4. Use the speed controls to slow down or speed up playback. 5. Type your transcription in the text area, or click "Auto-Transcribe" for browser-based speech recognition. 6. Copy or download your transcription when done.
All tools 100% free & private. alltoolscombined.com
