OGG is the format most people meet without knowing it: WhatsApp and Telegram voice messages are OGG files with Opus audio inside, and it's the default for plenty of open-source recorders. Trustample transcribes OGG directly — both Opus and the older Vorbis codec — so the voice note you exported uploads as-is. We verified this with real OGG files before publishing this page, not by assuming.
The voice-note workflow is the common case: save or export the message as a file, drop it in, and a short note transcribes in seconds. A backlog of them lands in your dashboard as each finishes — useful when a week of someone's voice messages needs to become something you can actually search and reply to properly.
How it works
- 1Export the voice note or recording as a file (WhatsApp: share → save; Telegram: save to files).
- 2Upload the .ogg (or .oga/.opus) — no conversion to MP3 needed, ever.
- 3Edit inline if needed, then copy the text or export a document.
Frequently Asked Questions (FAQs)
Do I need to convert OGG to MP3 first?
No — and converting first costs you quality for nothing. OGG uploads and transcribes directly; re-encoding lossy audio to another lossy format only degrades it. Every guide that tells you to convert first is adding a pointless step.
How do I transcribe a WhatsApp voice message?
Export it as a file — long-press the message, share, save to your files (it arrives as .ogg or .opus) — then upload it here. Works in your phone's browser too, no app install. The same flow covers Telegram voice messages.
Opus or Vorbis — does the codec inside matter?
Both transcribe fine. Opus (the modern codec, used by WhatsApp and Telegram) is actually excellent for speech — it was designed for it. You don't need to know or check which one your file uses.
Are voice messages private after upload?
Yes — encrypted storage, no AI training on your recordings, 30-day auto-delete with instant manual delete, and an optional paranoid mode that erases the recording the moment transcription completes.
