Remove subtitle formatting, speakers and SDH notes
Reduce a subtitle file to just the dialogue for translation or transcription. Pick exactly which kinds of markup you want gone.
What can be removed
HTML-style tags (<i>, <b>, <font color=...>), ASS override tags ({\an8}, {\pos(...)}), speaker labels at the start of a line (Tanaka:, NARRATOR:), SDH annotations such as [MUSIC], [APPLAUSE] and (laughs), the ♪ music note, and the leading hyphen used for dialogue.
SDH annotations
Subtitles for the deaf and hard of hearing describe sound inside brackets. That is usually noise for a translation or a summary, so all of it can go at once — square brackets, parentheses and the Japanese full-width bracket forms.
Cues left empty
A cue that contained only a sound annotation ends up empty. By default such cues are deleted and the file is renumbered; turn on the keep option if you need the timings preserved.
Frequently asked questions
Can I keep italics but drop the positioning?
Turn tag removal off to keep <i>. To drop only ASS positioning, convert to SRT first: that conversion removes override tags while keeping italic, bold and underline as <i>, <b> and <u>.
Will removing speaker names eat into the dialogue?
A prefix only counts as a speaker when it is short and free of sentence punctuation, so a line like "See you at 10:30" is left alone. Review the result before saving if in doubt.
Are my files uploaded to a server?
No. Everything runs as JavaScript inside your browser and the file contents never leave your machine, which makes it safe for unreleased scripts and confidential recordings.
Is it free? Do I need to sign up?
It is free, needs no account and nothing to install, and there are no usage limits.
