Workflow notes

How to use this Cleaner tool

Use this when a subtitle file needs a cleaner handoff before upload, review, or conversion. The tool keeps cue timing intact while removing leftover HTML tags, fixing spacing, and exporting cleaned SRT, VTT, or ASS text locally with no upload.

  1. Add a supported subtitle file. Upload or paste a supported subtitle file (.srt, .vtt, .ass, .ssa, .txt), or load the sample input to see the expected structure.
  2. Run the Cleaner 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

  • Cleaning text before saving a backup of the original file.
  • Assuming cleanup can repair badly timed subtitles.
  • Leaving malformed SRT or VTT timestamps for the video platform to reject later.

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 subtitle cleaner when SRT, VTT, or ASS text has leftover HTML tags, messy spacing, or formatting that should be cleaned before upload.

  • Remove leftover HTML tags from subtitle text before upload.
  • Fix messy subtitle spacing without changing cue timing.
  • Clean imported SRT, VTT, or ASS text before conversion.
  • Prepare a cleaner subtitle file for review, handoff, or platform testing.
