A small Chrome extension that shows the estimated download size next to every YouTube quality option, right in the settings menu, calculated entirely on your device.
YouTube's own player already loads size information for every available stream. This extension just displays it: no scraping, no extra requests.
Every calculation happens on your device, the moment you open the settings menu. Nothing is sent anywhere, ever.
Badges sit inside the real settings panel, styled to look like they belong there, not a separate overlay bolted on top.
No accounts. No analytics. No servers. The extension makes zero network requests of its own.
