A whole new look. Fill your Safari window with any video, now with sleek glass controls, Up next and comments on YouTube, plus a solid mode if you prefer. Most “fullscreen” browser extensions just maximize your entire window. Fill Window actually makes the video itself fill the space — instantly. A BEAUTIFUL, MODERN DESIGN Everything in Fill Window has a sleek glass look: floating controls, rounded panels and buttons that respond as you hover and click, all letting your video show through. Prefer something more solid? Turn off the glass effect in settings for darker, opaque controls instead. WHAT IT DOES Click the toolbar icon, use the keyboard shortcut, or hover a video for a quick expand button — Fill Window expands it to fill your current Safari window. No need to leave windowed mode, no native fullscreen animation, no juggling other apps you want to keep visible alongside it. Once it’s filling the window: Single-click the video to play or pause Double-click, press Escape, use the Close button, or press Back in Safari to exit Skip back or forward with the arrow keys or the on-screen buttons Scroll to zoom in, then click-drag to reposition — a Reset button snaps back to fit Hover the seek bar for a preview of what’s at that timestamp, including a real thumbnail on sites that support it A loading indicator appears during genuine buffering, so you’re never left wondering if something’s stuck MORE ON YOUTUBE, WITHOUT LEAVING FILL MODE Up next: open a panel of suggested videos and switch to one on the spot Play next: line videos up in a queue and they play in order when the current one ends Autoplay: turn YouTube’s autoplay on or off from the same panel Comments: scroll down on the video and the comments slide up from the bottom Jump ahead: if you have YouTube Premium, the Jump ahead button appears in fill mode too Quality: switch playback quality from the controls bar MULTIPLE VIDEOS ON ONE PAGE Click the toolbar icon and you’ll see every video on the page listed with a thumbnail — pick the one you want. If there’s only one, Fill Window fills it straight away. ONE CLICK, RIGHT WHERE YOU’RE LOOKING Hover any video and a small expand button appears right on top of it — no need to reach for the toolbar at all. Choose which corner it shows up in and how big it is, with a live preview in settings, or turn it off entirely if you’d rather stick to the toolbar or keyboard shortcut. MADE YOUR WAY A full settings page, in light or dark mode to match your Mac, lets you switch the glass effect on or off, and choose how long the controls stay visible before fading out, how far each skip jumps, and whether the playback buttons show on the video. It also includes a built-in guide to the gestures and shortcuts. BUILT FOR REAL WEBPAGES Modern video players often sit inside containers with CSS effects that break naive “make it fullscreen” tricks. Fill Window handles this properly, so it works reliably across a wide range of sites and custom video players, not just the simplest cases. PRIVACY, DONE PROPERLY Fill Window collects nothing. No analytics, no tracking, no accounts, no data sent anywhere. It only ever works with the page you’re already viewing: to find and control the video and, on YouTube, to show that page’s own suggestions and comments. Nothing is logged or transmitted. Your Play next queue stays in the tab and is gone when you close it. Full details in the privacy policy linked on this page. FREE, WITH AN OPTIONAL TIP No ads, no subscriptions, no feature locked behind payment. Everything works fully for free. If you’d like to support future development, there’s an entirely optional tip built in through Apple’s own In-App Purchase — never required, never intrusive. Fill Window is built and maintained by an independent developer.
