Normalize Subtitle Punctuation


Inconsistent punctuation makes subtitles look amateur. Our normalizer fixes spacing around punctuation, standardizes ellipses, corrects quote marks, and ensures professional formatting throughout your subtitle file.


How the Normalize Subtitle Punctuation works


Upload your subtitle file with inconsistent punctuation. The tool fixes common issues: spaces before commas, missing spaces after periods, varied ellipsis styles, and mixed quote formats. Smart detection preserves intentional formatting while fixing errors. The normalized output looks professional and reads smoothly. Perfect for subtitles from various sources or multiple editors.

Punctuation consistency matters for readability. Viewers shouldn’t notice formatting – they should focus on content. This tool ensures professional presentation, making your subtitles look like they came from a single, skilled editor rather than cobbled together from various sources.
