Why use Whisper AI free transcription?
100% free in the browser
No subscription for this tool. Transcribe audio, voice, or URLs with OpenAI Whisper models running client-side.
Private by design
Your audio is not uploaded to our servers for transcription. Processing stays on your device in a Web Worker.
No sign-up required
Start immediately — no account, no API key. Ideal for one-off files, quick memos, or trying speech-to-text privately.
How free browser transcription works
Three steps from audio to text — all local after the model loads.
01
Add your audio
Upload a file, record with your mic, or paste an audio URL — depending on which free tool you use.
02
Choose language & model
Pick source language and a Whisper model size. Quantized models load faster on most devices.
03
Copy or export
Read the transcript on the page, copy to clipboard, or export TXT / JSON — your text, your workflow.
Who generates SRT from video?
Video editing workflows
Import SRT into Premiere, DaVinci Resolve, or Final Cut as a starting caption track — generated on your machine.
Accessibility & courses
Add closed captions to training and lecture videos without sending raw footage to a cloud subtitle API.
Free, private transcription
Built for people who cannot send sensitive audio to the cloud.
- Transcription runs in your browser via a Web Worker — not on Whisper AI servers.
- Audio files are not uploaded for the speech-to-text step on these free tool pages.

Video to SRT FAQ
Which video formats can I convert to SRT?
Common formats such as MP4, WebM, and MOV with an audio track work in supported browsers. Audio is decoded locally, then Whisper adds timestamps.
What is an SRT file and how do I use it?
SRT is a standard subtitle format with numbered cues and time ranges. Download the .srt and upload it to YouTube, Vimeo, or your editor.
How accurate are auto-generated subtitles?
Accuracy depends on audio quality, language, and model size. Whisper produces a strong draft; review and adjust cues in your editor before publishing.
Is video to SRT free without registration?
Yes. Transcribe and export SRT locally with no account required.
Is this transcription tool really free?
Yes. These pages are free to use with no paywall for local browser transcription. Optional paid plans apply to the Chrome extension and cloud features, not this on-page Whisper tool.
Is my audio private when I transcribe here?
For these free tools, speech-to-text runs locally in your browser. We do not upload your audio to our servers for transcription. URL mode fetches the file from the link you paste; that request goes from your browser to the host.
