Who Benefits from Whisper Web?
Frequently Asked Questions
Can you convert OPUS to text?
Yes. Choose an OPUS file or paste a public direct audio link, select the spoken language, and start transcription. Whisper Web creates text you can edit, copy and download. Use timestamps to listen back and check specific passages.
What should I know before transcribing an OPUS file?
Opus is commonly used for voice chat and web audio. Browser support depends on how the Opus stream is packaged; if it cannot be decoded, export a WAV or MP3 copy.
Why use Whisper Web to transcribe OPUS files?
You can start without signing up, review the text alongside the original audio, and export your corrected transcript on the same page. Free transcription runs on your device, while Pro offers cloud processing for longer recordings and batch workflows.
How accurate is OPUS transcription?
Accuracy depends on the spoken language, recording quality and selected model. Clear speech gives the best results; background noise, strong accents and overlapping voices can cause mistakes. Review names, numbers and important quotes against the original audio before using the transcript.
Can I edit my OPUS transcript before downloading?
Yes. Edit paragraphs and search for words directly on this page. Your corrections are included when you copy or download the result. Save your local transcript before leaving the tab; Whisper Web does not include a human proofreading service.
Which formats can I export my OPUS transcript to?
Download TXT or Word (DOCX), with optional timestamps, or export SRT and VTT subtitles. JSON export and copying the text are also available. All exports use your corrected text.
Do you offer free OPUS transcription?
Yes. Transcribe files up to 20 minutes and 200 MB each for free in your browser, without signing up or entering a credit card. Pro uses cloud processing for longer recordings, batch uploads and saved cloud history.
Which languages can I transcribe my OPUS file in?
Whisper Web supports 98+ languages, including English, Spanish, French, German, Chinese, Japanese and Korean. Choose the spoken language or use automatic detection. This page transcribes the original speech; it does not automatically translate your transcript.
Can I import an OPUS recording from a link?
Use a public direct link to an audio file that the browser can access. A YouTube page or a private Google Drive or Dropbox sharing page is not a direct media file. If importing fails, download a recording you own or have permission to use and select the file from your device.
Does my OPUS recording leave my device?
Free transcription runs locally in your browser. Pro uploads media for cloud processing and saved history. Choose the workflow that suits your recording, and copy or download local results before closing the tab.
