Overview

Fill the empty margins around the YouTube player with a soft blur that matches the video, or a theme-matched solid color.

☕ Enjoying youtublur? Support development: https://buymeacoffee.com/kkyto641 youtublur fills the empty space around the YouTube player. When the video doesn't fill the window, YouTube leaves blank margins and side gaps around the player. youtublur fills those gaps with one of two styles: • Blur: a soft blur that follows the video's colors in real time, so the margins blend with what you're watching. • Solid: a solid color you choose, so the margins match your theme. Only the area around the player changes. The video itself is untouched. No filter is applied to it, and this is not a thumbnail blur. How to use • Click the toolbar icon to switch between Blur and Solid. • Adjust the blur strength, or pick your solid color. Where it works best Any layout that leaves margins around the player, such as theater mode on classic YouTube or a wide window with side gaps. Lightweight and privacy-friendly: youtublur collects no data.
