WhatsApp Voice Note to Text

To transcribe a WhatsApp voice note, save or forward the audio and drop it into the box below — the .opus or .ogg file works as is, no conversion. JustTranscribe turns it into text with timestamps, detects the language, and lets you copy, translate or export it.

Useful for the long ones: a client's twelve-minute message, a professor's instructions, a family update in another language. First transcript free, no account.

First transcript free, no account. OPUS/OGG accepted directly.

[0:00] grabado por Claudia Hernández, la bruja de Itatí de Eloy Fariña Núñez.
[0:08] En la humilde aldea de Itatí, fundada por el venerable Fray Luis de Bolaños de la Orden de San Francisco, a principios del siglo XVII, en la margen izquierda del
[0:19] río Paraná, vivía junto a la casa de mis padres, en un rancho oculto entre naranjos, sobre la plaza principal, donde se alza el santuario de la Virgen
[0:31] Taumaturga, una mujer llamada Bernarda, que pasaba por ser bruja, en el concepto popular, con dos hijos menores sumamente parecidos a ella.

Source: the first 42 seconds of "La bruja de Itatí" by Eloy Fariña Núñez, read by Claudia Hernández for LibriVox (public-domain recording, via archive.org), saved as a mono 16 kbps .opus file — the same codec and bitrate WhatsApp uses for voice notes — uploaded as-is on 19 August 2026, no conversion. The language was detected (Spanish) and the names came through correctly: Itatí, Fray Luis de Bolaños, Virgen Taumaturga. A Spanish sample on purpose: most voice notes we see are Spanish, and the tool does not care which language you speak.

Frequently asked questions

Doesn't WhatsApp transcribe voice notes itself?

Newer versions can, on the phone, once you enable it — but only inside the chat, in a limited set of languages, with no export and no timestamps. For long audios or for text you need in a document, upload the file here.

Do I need to convert the file to MP3?

No. OPUS, OGG, M4A, AAC, MP3, WAV and FLAC are accepted directly. Converting adds a step and can degrade the audio.

Can I transcribe a voice note in another language?

Yes. The language is detected automatically, and you can translate the transcript into 111 languages afterwards.

Can I do this from a computer?

Yes. Download the audio from WhatsApp Web or the desktop app and drag it into the browser at justtranscribe.ai.

Is it free?

Yes. The first transcript is free with no account (up to 40 minutes); after that, a free account raises the limit to 150 minutes and 500 MB per file — unlimited transcripts during the beta, no card needed.
