Custom Subtitles for YouTube™

Shows professional subtitles in your language, or your own SRT, VTT, SBV or ASS files, in place of YouTube's automatic captions.

Custom Subtitles for YouTube™ shows better subtitles on YouTube videos, in place of YouTube's automatic captions. • Professional subtitles for selected videos. Some videos have subtitles in Spanish and in their original language, made to Netflix's timing and reading-speed guidelines. When the video you watch has them, they appear in your language. Other videos stay as they are. • Your own subtitle files. Open an SRT, VTT, SBV or ASS file on any video. The extension keeps it for that video, in your browser only, and shows it every time you come back. • Your style. Choose the font, size, text color and opacity, character edge, background and height from the toolbar icon, with a live preview. • Made for YouTube's player. A button next to CC picks the language, your file or Off. Turning CC on turns these subtitles off, and the other way round. Off lasts on every video until you choose a language again. Privacy: no account, no ads, no tracking. The extension asks its server for a video's subtitles only when that video has published subtitles. Your own files never leave your browser.
