Shows estimated file size (MB/GB) next to each YouTube quality option, fully client-side — no server involved. YouTube Video Size shows an estimated file size in MB or GB next to every quality option in YouTube's settings menu, so you can see how much data you'd use before switching resolutions. HOW IT WORKS YouTube's own video player already receives the size of every available quality stream as part of normal playback. This extension simply reads that information from the page and displays it clearly, right next to each option. Everything runs locally in your browser, no video data is sent anywhere, and no external server is involved at any point. FEATURES - A size badge next to every available quality (144p up to 4K, where offered) - A live indicator near the player controls showing your current quality and its estimated size - Minimal red badges styled to match YouTube's own look - Works automatically — no setup, no configuration, no account needed WHAT IT DOESN'T DO This extension does not download, save, or help you download any video. It only displays size information already present on the page. PRIVACY No network requests of its own, no data collection, no tracking. It reads data your browser already receives from YouTube while a video is loaded.
