About the Free Audio Transcriber
ToolGenie's Audio Transcriber is a free online tool that converts audio and video files into accurate, editable text. It is powered by OpenAI Whisper, one of the most accurate speech recognition models available — delivering excellent results even for accented speech, technical vocabulary, and moderate background noise.
Unlike simple dictation tools, this transcriber works with pre-recorded audio and video files, making it perfect for transcribing podcasts, interviews, meetings, lectures, webinars, voice memos, and YouTube videos. Because it captures word-level timestamps, you can export ready-to-use SRT and VTT subtitle files for captioning and video editing — not just a plain text transcript.
Everything runs securely: your file is sent to the transcription API for processing only and is never stored. There is no sign-up, no watermark, and no cost — just fast, private audio-to-text conversion in your browser.
Frequently Asked Questions (FAQ)
1. How do I transcribe an audio file to text?
Upload your audio or video file, choose an AI model and language (or leave it on Auto-detect), then click Transcribe Audio. In seconds you'll get an editable transcript that you can copy or download as plain text, timestamps, or SRT/VTT subtitles.
2. What audio and video formats are supported?
The tool supports common formats including MP3, WAV, M4A, AAC, FLAC, OGG, WEBM, MP4, MPEG, MPGA, and MOV. Files must be under 25 MB — for longer recordings, compress the audio or split it into smaller parts before uploading.
3. Can I generate SRT and VTT subtitles from audio?
Yes. After transcription the tool produces timestamped segments, so you can switch to the SRT or VTT tab and download ready-to-use subtitle files for YouTube, Vimeo, video editors, and captioning workflows — no extra formatting required.
4. How accurate is the AI audio transcription?
The transcriber uses OpenAI Whisper Large v3, which achieves roughly 95–99% word accuracy for clear speech. It handles accents, technical vocabulary, and moderate background noise well. For the highest accuracy on difficult audio, select the Whisper Large v3 model.
5. Is the audio transcriber free to use?
Yes — the ToolGenie Audio Transcriber is completely free. There is no sign-up, watermark, or hidden paywall. Upload your file and download your transcript or subtitles at no cost.
6. Is my audio file stored or kept private?
ToolGenie does not store your audio or transcripts. Your file is sent securely to the transcription API for processing only and is not retained afterward. Transcripts are generated on demand and never saved on ToolGenie's servers.
7. Which languages can the audio transcriber handle?
Whisper supports 50+ languages including English, Spanish, French, German, Italian, Portuguese, Dutch, Chinese, Japanese, Korean, Arabic, Hindi, Russian, Turkish, and Polish. Use Auto-detect to identify the spoken language automatically, or select a language for the best results.
8. Can I transcribe video files too?
Yes. You can upload video files such as MP4, WEBM, and MOV. The tool transcribes the spoken audio, making it ideal for captioning videos, generating subtitles, and turning webinars, lectures, or interviews into searchable text.
Tips for the Best Audio Transcription Results
- Use clear source audio: recordings with minimal background noise and a close microphone produce dramatically more accurate transcripts.
- Pick the right model: use Whisper Large v3 Turbo for speed, or Large v3 when accuracy matters most on accented or noisy audio.
- Set the language when you can: selecting the exact spoken language often beats Auto-detect for short or heavily accented clips.
- Stay under 25 MB: for long recordings, export a compressed MP3 or split the file into segments before uploading.
- Export subtitles for video: use the SRT tab for most video platforms and editors, or VTT for HTML5 web video captions.
- Proofread names and jargon: AI transcription is excellent but not perfect — review proper nouns, brand names, and technical terms after downloading.
