WhatsApp voice to text, for the whole conversation at once.
Export the chat with media and upload it once. Every voice message in it is transcribed in the language it was spoken, and each transcript lands at the moment it was sent, beside the written messages around it.
- Photos & videos stay on your device. Audio sent for transcription only if you opt in. If you select a video, your browser extracts and sends only its audio track for transcription; the video and its visual content stay on your device.
Hear it, then read it
Three voice messages, transcribed the way yours will be
Press play on any of them. The text underneath is what came back from the recording, in the same player and the same transcript block you get inside a recap.
- opus
- m4a
- ogg
- mp3
PTT-20250118-WA0023.opus
Transcription:
Hey, real quick about the meeting yesterday — I think we should go with the second option for the homepage. Yeah, the second one.
PTT-20250118-WA0024.opus
Transcription:
Oh, and can you send me the Figma link? I wanna show it to Sarah before our call tomorrow at three.
PTT-20250118-WA0025.opus
Transcription:
Ah, and the budget — it's approved! So we can move forward with the contractor this week, no problem.
Audio is only sent for transcription when you ask for it.
How it works
Export with media
Export the WhatsApp chat with media. The .zip that comes out holds the recordings, usually named PTT-YYYYMMDD-WAXXXX.
Upload the ZIP
Upload the .zip exactly as your phone produced it. Every voice message inside is found and transcribed in the language it was spoken in.
Read the full conversation
Read the conversation as one thing, spoken and written together. Search it, quote it, and use the recap to find what was decided.
What you get
One readable conversation, not a folder of recordings.
The formats a WhatsApp export actually contains
Whichever one your phone wrote, the same upload reads it. There is nothing to convert first.
- OPUS — what WhatsApp normally records a voice message as, arriving as PTT-*.opus.
- OGG — the container that OPUS audio travels in, which is why the same recording is correctly called both.
- M4A — what some phones and older exports write instead of OPUS.
- MP3 — uncommon in a WhatsApp export, and read the same way when it appears.
What the text gives you that the recording cannot
The audio already exists. Everything you actually want to do with it needs words on a page.
- In place — each transcript sits at the moment it was sent, so a spoken reply reads directly under the written question it answers.
- Searchable — find the message where a price, a date or a name was said, instead of scrubbing through recordings to locate it.
- Quotable — copy the exact words with the date they were spoken into a document, an email or a claim.
- Covered by the recap — the automatic recap reads what was said out loud alongside what was typed, and follow-up chat answers a narrower question about it.
Key benefits
Every voice message in the export, transcribed in one pass
OPUS, OGG, M4A and MP3 handled by the same upload, with no converter step
Transcribed in the language it was spoken in, not translated by default
Each transcript kept in order, with the timestamp of the recording
Length measured from the audio itself, so the price you are quoted is the real one
The recap and follow-up chat cover the spoken messages, not only the typed ones
Use cases
