Workflow notes

How to use this SRT to VTT tool

SRT is common for handoff, but HTML5 video and browser players usually expect WebVTT. This converter adds the WEBVTT header, changes timestamp commas to dots, removes SRT cue numbers, and creates browser-ready captions locally.

  1. Add a supported subtitle file. Upload or paste a supported subtitle file (.srt, .txt), or load the sample input to see the expected structure.
  2. Run the SRT to VTT tool. Use the browser-based converter or repair action to process the subtitle file locally on your device.
  3. Review and download the output. Check the first few cues, the middle of the file, and the final cue before copying or downloading the result.

Input and output checklist

  • Use a complete subtitle file with valid cue timing when possible.
  • Keep a copy of the original file before replacing it in your workflow.
  • Review the first few cues, the middle of the file, and the final cue after export.
  • Test the downloaded output in the destination player, editor, or upload form.

Common mistakes to avoid

  • Missing the WEBVTT header after conversion.
  • Keeping comma-based SRT timestamps in a browser VTT file.
  • Uploading a subtitle file before checking cue text in the target player.

All processing runs in your browser, so the subtitle or video file does not need to be uploaded to a server. That is useful for client review files, unreleased videos, internal training material, and other caption workflows where the text should stay on your device.

When to use this tool

Use this free SRT to VTT converter when an HTML5 video player needs a clean `.vtt` file with the `WEBVTT` header, dot-based timestamps, and no SRT cue numbers.

  • Prepare SRT subtitles for HTML5 video tracks.
  • Add the WEBVTT header before using captions on a website.
  • Convert comma-based SRT timestamps to dot-based WebVTT timing.
  • Create browser-ready VTT captions without uploading subtitle files.
