📝 Subtitle Cleaner

The Subtitle Cleaner extracts spoken lines from SRT or WebVTT blocks, then can remove speaker labels, bracketed sound descriptions, HTML tags, duplicate lines, and extra spacing. Clean text and line-by-line output intentionally discard timing. If you select SRT or VTT as the output format, the tool rebuilds a valid-looking sequence with placeholder timestamps set to zero; it does not preserve the original cue timing or calculate new in and out points.

Use the SRT or VTT output only as a structural starting point that will be timed in a subtitle editor. Do not publish zero-time cues as finished captions. If timing must be preserved, keep the original subtitle file and make targeted edits in software that maintains cue boundaries. For new timed captions, use the Audio to Text workflow, review its Whisper-derived timestamps against the media, and then correct line breaks and timing before delivery.

For a TTS narration script, removing timestamps, cue numbers, markup, and repeated lines usually prevents the voice from reading production notation aloud. For an accessibility transcript, speaker identity and meaningful sounds may be essential, so leave speaker labels and sound descriptions enabled in the source. The sound-description rule removes text inside square brackets, parentheses, or braces; that can also erase citations, clarifications, or dialogue that happens to use those characters.

Duplicate removal compares simplified lines without punctuation and can remove a repeated phrase that was intentional. Review songs, chants, emphasis, and call-and-response material closely. Paste and file import are processed in the page, and Download creates a text file from the current output. You remain responsible for having permission to reuse the subtitle content. Downloading captions from a video platform does not automatically grant rights to republish or synthesize the dialogue.

Keep the original subtitle beside the cleaned copy and use a descriptive new file name. That small versioning step preserves timing, speaker context, and meaningful sound cues if a removal option proves too aggressive. The tool has no cloud revision history and its output box is not a substitute for an archived source file.
