A video speed controller is a browser extension or tool that allows you to change the playback speed (speed up or slow down) of HTML5 videos on websites. It gives you precise control beyond standard site speed menus.
You can control playback speed universally by installing our extension. Once active, you can adjust speeds using customizable keyboard hotkeys (like [ and ]), hover mouse-scroll gestures, or the overlay speed dashboard widget that appears on top of detected video players.
Yes! It works perfectly on YouTube. It allows you to adjust speeds beyond YouTube's native 2.0x limit, all the way up to 10.0x, in precise 0.05x increments.
Yes, it is optimized for students and professionals. It works on major course sites like Coursera, Udemy, Loom, and proprietary university portal players by detecting the underlying HTML5 video elements.
Absolutely. This Chrome extension detects any standard HTML5 <video> element on a web page and lets you speed it up to 10.0x using keyboard hotkeys or quick presets.
You can slow down any HTML5 video to 0.25x (quarter speed) in Chrome by pressing the [ key (default shortcut) or using the floating speed widget next to the player.
Yes. The default shortcuts are ] to speed up, [ to slow down, and \ to reset to 1x. You can also hold X for temporary acceleration. All keys are fully customizable in the Shortcut Manager.
Yes. The extension works seamlessly on subscription services like Netflix, Disney+, and Amazon Prime Video, letting you watch series at custom speeds (e.g., 1.15x) to match your viewing preferences.
Native video players often cap speeds at 2x, have rigid presets, or lock speed changes completely. A universal controller works across all platforms, supports fine-grained steps (like 0.05x adjustments), remembers your preferences per website, and allows customizable hotkeys.
Yes. You can instantly reset video playback back to the normal 1.0x speed by pressing the \ hotkey or clicking the speed pill on the floating widget.
Yes, the Universal Video Speed Controller is 100% free, free of ads, and open-source under the MIT license. You can download it directly from the Chrome Web Store.
No. We believe in absolute privacy. The extension does not collect, transmit, or monetize your browsing history or data. All configurations and watch statistics are stored locally on your device.
Visit the Chrome Web Store, search for "Universal Video Speed Controller", click "Add to Chrome", and pin it to your toolbar. It will start working on any video page automatically.
While the extension overrides speed settings on most HTML5 players, some sites enforce strict custom player scripts or require specific frame structures. If a video won't adjust, check that the extension is enabled for that site in your rules settings, or open a GitHub issue with the URL.
