Tool details

Subtitle Cleaner helps you clean subtitle text and remove formatting noise. Processing runs entirely in your browser, so subtitle files stay on your device and no upload is required. You can paste subtitle content or open local files, review cues in a preview table, and export final output in seconds. This is useful for social clips, tutorials, interviews, podcasts, and product videos that require reliable captions. Built-in checks help detect invalid timestamps, overlaps, and readability risks before publishing, reducing revision cycles and improving consistency across platforms.
