How to convert SRT to VTT
Choose your file, convert it in your browser, and download the new subtitle format.
Step 1
Choose your SRT file
Select or drop a .srt subtitle file. It never leaves your device.
Step 2
Convert it instantly
Fast Transcriber changes the subtitle header and timestamp format in your browser.
Step 3
Download your VTT
Save a clean .vtt file for HTML5 video players, websites, and supported platforms.
Cue text and timestamps are preserved. Only the file structure changes to match VTT.
Prepare your WebVTT captions for playback
Use this converter when you already have SRT subtitles and your destination asks for VTT. Keep the matching video or audio file: the downloaded caption file contains text and timing, not the recording.
Check formatting and timing
Conversion keeps cue start and end times and basic bold, italic, and underline tags. SRT font and span formatting is omitted with a warning. Appearance still depends on the destination player, so check its caption settings after import.
Changing formats does not correct an existing delay or rewrite the words. If you trimmed the recording, check that the captions still match the edited version.
Test the downloaded file
Load the VTT into your intended player and review the beginning, middle, and end. Check line breaks, punctuation, special characters, and synchronization before publishing.

FAQ
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.
