Frequently asked questions
Is this audio transcriber free?
Yes, free with no signup. It uses OpenAI's open-source Whisper model (large-v3-turbo). To keep it free for everyone, each user gets 6 files per hour, up to 25 MB each.
What file formats are supported?
MP3, M4A, WAV, OGG, WebM, FLAC, and MP4 video audio - up to 25 MB per file. A 25 MB MP3 is roughly 25-50 minutes of speech depending on bitrate.
How accurate is the transcription?
Whisper large-v3 is one of the most accurate open speech models available and handles accents, background noise, and technical vocabulary well. It auto-detects the language - it supports dozens, including English, Hindi, Spanish, French, and German.
Can I get subtitles for a video?
Yes - after transcribing, click 'Download .srt' to get a subtitles file with timestamps that works in YouTube, Premiere, CapCut, and VLC.
Is my audio stored anywhere?
No. The file is sent to the transcription engine, converted to text, and immediately discarded. Nothing is saved on our servers.
