Audio to Text Converter — Free AI Transcription, No Upload
Turn recordings into text without uploading them anywhere. UtilHub's free audio to text converter runs the Whisper speech recognition model directly in your browser, so interviews, lectures, meetings, voice memos, and podcasts are transcribed on your own device. Drop an MP3, WAV, M4A, OGG, or FLAC file — or a video such as MP4 or MOV — choose the spoken language or let it be detected automatically, and read the transcript as it appears. Copy the text, or download it as a TXT file or as SRT and VTT subtitles with timestamps. There are no minute limits, no sign-up, and no per-file price, and after the model downloads once it even works offline.

Frequently Asked Questions
Is this audio to text converter really free?
Yes. Transcription runs on your own computer or phone instead of a paid server, so there is nothing to charge per minute. There is no account and no daily limit. The only cost is a one-time download of the speech model, which your browser keeps for later visits.
How accurate is the transcription?
Clear speech with little background noise is usually transcribed very accurately, including punctuation. Accuracy drops with strong accents, overlapping speakers, music, or poor microphones. For difficult recordings choose "Most accurate", which downloads a larger model and runs slower, and select the spoken language instead of automatic detection.
Can I convert a video to text?
Yes. Drop an MP4, MOV, or WebM video and the tool transcribes its soundtrack. Download the result as SRT or VTT to add subtitles in YouTube Studio, Premiere Pro, DaVinci Resolve, CapCut, or VLC.
How long does transcription take?
It depends on the recording length, the accuracy level, and your device. On a recent computer with WebGPU, the balanced model usually works faster than real time, while older computers and phones can take longer than the recording itself. Keep the tab open while it works; you can follow the progress and cancel at any time.
