YTSubConverter is a free, open-source subtitle conversion tool designed for creating richly styled YouTube captions. It converts Advanced SubStation Alpha (ASS) subtitles into YouTube's YTT format while preserving supported visual effects. Users can customize fonts, colors, transparency, text positioning, outlines, and shadows. Karaoke timing supports syllable-by-syllable lyric displays and current-word highlighting. Additional formatting includes vertical text, ruby annotations, and animated transitions. The application also converts SBV files to SRT and supports TTML-to-YTT conversion. It works with subtitles created in editors such as Aegisub. YTSubConverter is available for Windows, macOS, and Linux.
