Upload your file
Drag and drop your audio, video, PDF, or image file. We support files up to 5GB.
Upload a Portuguese recording — Brazilian or European — and get an accurate transcript, or translate it directly into English text. Free for files under 5 minutes.
By using this tool, you agree to our Terms of Service. 1Transcribe is not liable for any legal consequences resulting from your unauthorized use of this tool.

Upload your Portuguese recording to 1Transcribe and OpenAI's Whisper models return an accurate transcript with speaker labels in minutes — Brazilian and European Portuguese are both handled automatically. You can also translate the Portuguese speech directly into English text in one step. Files under 5 minutes are free with no signup; longer files up to 10 hours need a subscription.
Portuguese comes in two major flavors that sound remarkably different. Brazilian Portuguese is open and vowel-rich, while European Portuguese compresses unstressed vowels so heavily that even Brazilians sometimes struggle to follow fast speech from Lisbon. Speech tools tuned only for Brazilian audio often fall apart on the European variant.
1Transcribe runs OpenAI's Whisper, trained on Portuguese from both sides of the Atlantic — plus Angola and Mozambique — so recordings from São Paulo and Porto come back equally accurate. Automatic language detection means there is no dialect switch to set: just upload the file.
Both intents are covered:
Brazil is one of the world's heaviest users of WhatsApp voice messages, and long "áudios" from colleagues, clients, and family are a daily reality. Forward the OPUS file to 1Transcribe and read it as text — notes under 5 minutes are free. For bigger jobs, single files up to 10 hours and 5 GB are supported: research interviews, church services, podcast episodes, and full meeting recordings, with automatic speaker diarization so you always know who said what.
Accuracy reaches up to 99.9% on clear audio in both Portuguese variants. Upload audio as MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, AMR, or WMA, or video as MP4, MOV, AVI, MKV, or WEBM. Files are never used to train AI models and are deleted after 14 days, and 1Transcribe works in the browser and the iOS, Android, Mac, and Windows apps with nothing to install.
