About SubtitlesForYoutube
SubtitlesForYoutube is a Chrome extension that displays external subtitles on YouTube videos. Users can drag and drop an SRT file or a zipped SRT file onto the upload box on a YouTube video page, and the subtitles appear over the video.
The extension can also search for subtitles on OpenSubtitles.org and Amara.org from the video page and load them. The source notes that only about 5-10% of YouTube videos have matching subtitles on those sites, so search may not find subtitles for every video. Searches send requests to those external services.
Key features

- Search for and load subtitles from OpenSubtitles.org and Amara.org on the video page
- Keyboard shortcuts to toggle subtitles, adjust timing, and change subtitle size

Best for: YouTube viewers who already have an SRT subtitle file for a video and want to display it on the video page.
