SpeedUp — Video Speed Controller

Control the playback speed of HTML5 videos from a clean, fast popup. Works on YouTube, Netflix, Prime Video, and almost any site.

SpeedUp lets you control video playback speed on almost any website — instantly, from a clean popup, with no page reload needed. Most sites only offer a handful of fixed speeds (1x, 1.25x, 1.5x, 2x). SpeedUp removes that limit: pick any speed from 0.25x up to 16x, fine-tune it in 0.25x steps, or type an exact custom value. KEY FEATURES • Works on virtually any site with HTML5 video — YouTube, Netflix, Prime Video, Udemy, Coursera, news sites, and more • Fine-grained speed control in 0.25x increments, plus a custom speed input for exact values • One-tap Reset back to normal speed • "Apply to all videos" mode for pages with multiple video players • Your chosen speed sticks automatically — even through ads, quality switches, or a playlist auto-advancing to the next video • Lightweight popup UI that opens instantly, with no impact on page load or browsing performance • Works entirely offline: no account, no sign-in, no tracking FREE VS PRO The free version supports speeds up to 3x — enough for most everyday use (lectures, tutorials, podcasts-style videos). SpeedUp Pro unlocks the full range up to 16x, ideal for skimming long recordings, reviewing raw footage, or power-users who want maximum control. Pro is a one-time purchase — no subscription. PRIVACY SpeedUp does not collect, transmit, or sell any of your data. Your speed preference is stored locally in your browser using Chrome's storage API and never leaves your device. The extension only requests the permissions it needs to detect and control video elements on the page you're viewing. Install SpeedUp and take control of how fast you watch.
