Upload any standard .srt subtitle file and play it over the YouTube video you are watching.
Adjust subtitle size, text color and screen position so captions fit the video and your eyesight.
Subtitles are drawn over YouTube's native player, so playback controls and quality settings are unchanged.
Runs locally in the browser with no account required; the developer declares no user data is collected or sold.
A small extension that installs in seconds and adds almost nothing to your browser's memory use.
YouTube Subtitle Loader solves a very narrow but very annoying problem: YouTube videos whose built-in captions are missing, wrong, or in the wrong language. You open the video, click the extension icon, and upload an SRT file from your computer. The extension then renders those cues on top of YouTube's standard player, so playback stays exactly as you are used to.
Appearance is adjustable. You can change the subtitle font size, text color and vertical position so the captions stay readable without covering what matters on screen. There is no account, no server round-trip and no lock-in — it is a single-purpose utility that does one job.
The developer is an independent creator who built the extension with AI assistance after failing to find a working subtitle loader elsewhere, and published it for free. According to the Chrome Web Store listing the extension does not collect or sell user data, and it works with YouTube's normal video player rather than a replacement one.
Overlay a translated SRT file on a foreign-language video to read along while you listen to the original audio.
Add readable subtitles to videos that have no official captions or auto-generated tracks.
Replace inaccurate automatic captions with a hand-corrected SRT so you can quote the video precisely.
Load prepared subtitle files onto lecture videos so students can follow along at their own reading speed.
