Simple Auto HD (Open Source)

Pick your YouTube quality once and every video plays at it — up to 8K, plus theater mode. Works on Shorts and YouTube Music.

Tired of YouTube quietly dropping you to 480p? Simple Auto HD sets the quality you want on every video, automatically — no more opening the settings menu each time you press play. Choose a resolution once, anywhere from 8K down to 144p, or let it take the best the video offers. Ask for more than a video has and it quietly settles for the next best rather than failing. Whatever you pick, you get the highest frame rate available at that resolution. It works through YouTube's own player rather than clicking through the menu for you, so nothing flickers open on screen, and your choice sticks when YouTube autoplays the next video or returns from an ad. • Any resolution from 8K (4320p) down to 144p, or simply "best available" • Works on YouTube Shorts, with a switch to turn that off • Optional theater mode, kept in sync when you toggle it yourself or press T • Optional 1080p Premium (enhanced bitrate) for Premium subscribers — off unless you ask for it • Works in every YouTube interface language, not just English • Also runs on YouTube Music and the mobile site • Light or dark popup, or follow your system Private by design: no tracking, no analytics, no accounts. The extension makes no network requests at all, and the only permission it asks for is storage, to remember your settings on your own machine.
