OPUS Message Transcriber
WhatsApp and Telegram users know OPUS – it’s the format behind every voice message you send. Our OPUS converter specializes in transcribing these quick voice notes, handling the typical challenges of mobile messaging audio like background noise, quick speaking, and informal language. Turn those voice messages into text you can search, save, and share.
How the OPUS Message Transcriber works
Grab the OPUS file from your WhatsApp or Telegram folder and upload it here. The converter is optimized for typical voice message lengths (30 seconds to 5 minutes) and handles multiple languages seamlessly. The output preserves the conversational tone while adding proper punctuation for readability. Copy the text directly back to your chat or save it for your records.
Voice messages are convenient to send but a pain to review later. OPUS transcription solves this by converting your WhatsApp voice notes into searchable text. Find that address someone mentioned, review voice instructions while in a quiet environment, or simply archive important voice messages in text form. Essential for anyone managing business communications through messaging apps.
