Frequently asked questions
What is the difference between SRT and VTT?
SRT is a widely supported subtitle format that uses comma-separated milliseconds. WebVTT is designed for web video, begins with a WEBVTT header, and uses periods in timestamps.
Is this SRT to VTT converter free?
Yes. You can convert SRT files to VTT for free without creating an account, adding a watermark, or entering payment details.
Is my subtitle file uploaded?
No. The conversion runs locally in your browser. Your subtitle text is not uploaded to Fast Transcriber or stored on our servers.
Will the converter keep my subtitle timing and text?
Yes. Cue timing and subtitle text are preserved while SRT timestamps are changed to the WebVTT format and the required WEBVTT header is added.
Where can I use a VTT file?
VTT files work with HTML5 video players and many web publishing, learning, and video platforms that support WebVTT captions.
Need to create subtitles from audio or video?
