Ultrawider — Remove Black Bars & Fill Ultrawide Video (21:9/32:9)

Remove black bars: fill your 21:9 / 32:9 ultrawide with any video — even Netflix. Edges stretch, faces stay round. Free on YouTube.

You bought an ultrawide monitor. Almost every video on the web is still 16:9 — either sitting between thick black bars that eat ~26% of your screen, or "stretched to fit" by tools that make every face on screen ~30% wider. Ultrawider fixes both. Its Smoothie warp fills your 21:9 / 32:9 panel edge to edge while the center of the picture — where people actually are — stays geometrically untouched. And it works everywhere your browser plays video — including DRM-protected streaming like Netflix, where other tools fall back to a plain crop. HOW IT WORKS Most "stretch to fit" tools do uniform scaling: people get fat, everyone looks like they're in a fun-house mirror. Ultrawider uses a quintic non-linear warp (NLS): the center 60% of the frame stays geometrically correct, and only the outer 20% on each side gets stretched to fill the extra width. Faces stay round. Sports replays look natural. Movie close-ups stay cinematic. Smoothie works on every video — including DRM-protected streams, where most warping tools give up. It reads nothing from the frame, so content protection is never in the way. Prefer a plain zoom instead? Crop mode fills the screen the same way "object-fit: cover" does, cropping top/bottom instead of pillarboxing — pick whichever you like, per site. The result: your ultrawide monitor finally pays for itself. WORKS EVERYWHERE Remove black bars anywhere video plays in your browser — no per-site whitelist: • Streaming services — full Smoothie warp even on DRM-protected video like Netflix, Disney+, Prime Video, Max, and Hulu, where most tools fall back to a plain crop or fail outright. It reads nothing from the frame, so content protection is never in the way. • Sports — live matches and replays fill the whole panel, and the non-linear warp keeps players' proportions natural. • Free forever on YouTube — Smoothie and Crop run unlimited, no license needed. • Everything else — any site with an HTML5 video player. New video sites work automatically, without extension updates. FEATURES • Smoothie mode — the quintic NLS warp applied right on the video. The math that keeps faces round while edges stretch. Works even on DRM-protected video. Tunable concavity slider so you can dial it from "subtle" to "strong" per site. • Free preview everywhere — on sites other than YouTube, every Smoothie activation runs free for a full 3 minutes before reverting. Unlimited re-tries. See it fill your favorite streaming site before paying anything. • Crop mode — a uniform CSS zoom that fills the screen by cropping top/bottom. A clean alternative when you'd rather not warp at all — available on every video. • Auto-detect — picks the best available mode the moment you enter fullscreen. Per-host preferences remembered. • Aspect-aware — detects your monitor's actual aspect ratio (21:9, 32:9, 21:10, 32:10, dual-stacked — anything you've got) and computes the right stretch for your geometry. No setup, no manual configuration. • Universal video detection — works on YouTube and any other site with an HTML5 video player or embedded iframe player. No site-by-site whitelist; new video sites work automatically without extension updates. • Zero distortion when off — toggle Off and the video returns to its original aspect, no residual artifacts. PRICING • Free — Smoothie + Crop on YouTube, forever. No signup, no key.

If something's genuinely broken we'll make it right — see ultrawider.net/refund.html PRIVACY • We collect: anonymous install ID, anonymous usage events (active mode, hostname-only). Usage telemetry is off by default — enable it in the popup if you want to help; anonymous error reports are always sent (hostname-only, no URLs) to keep the extension working. • We do NOT collect: page URLs (only hostname), page content, video content, your identity, your watch history. • License keys are passed via URL fragment (#key=...) not query parameters — so they never appear in server logs, Referer headers, or browser sync. • Full policy at https://ultrawider.net/privacy COMPATIBILITY • Chrome / Edge / Brave / Vivaldi • Every ultrawide aspect ratio: 21:9 (3440×1440), 32:9 (5120×1440), 21:10, 32:10, portrait-stacked configurations — works on any ultrawide. • Works in browser fullscreen, presentation fullscreen, and detected automatically when a player goes fullscreen. FAQ Will faces look distorted? Smoothie's whole purpose is to keep the center undistorted. The central 60% of the frame is geometrically identical to the source; only the outer 20% on each side gets stretched. Movie close-ups, news anchors, sports broadcasters all look natural. Does it work in browser fullscreen (F11)? Yes — Ultrawider detects both Fullscreen API requests (the player's fullscreen button) and document-level fullscreen. Why did Smoothie switch off after a few minutes? That was the free preview ending. On the Free tier Smoothie runs full-time on YouTube; on every other site each activation gives you a free 3-minute preview — switch it back on as many times as you like. Pro removes the timer everywhere, including DRM-protected streaming. Crop is always available as a free alternative. Can I use it on more than 3 devices? The 3-device cap auto-rotates: the least-recently-used device unbinds when you activate on a 4th. Need a higher cap? Email hello@ultrawider.net. Is my watch history collected? No. We never log URLs or page content — only the bare hostname (e.g. "youtube.com") is ever sent, and usage telemetry is off by default; it only runs if you opt in from the popup.
