Gradient Lab
Free browser generator for animated gradient backgrounds, with PNG, 4K video, and live embed export
Gradient Lab is a free gradient background generator from Backgrounds Supply. It runs in the browser with no account. The mode panel lists 43 animated shader modes, such as Flow Mesh, Light Beam, Aurora, Halftone, and Plasma, plus presets. You set the colors, the gradient map blend, the speed, and the aspect ratio, and the canvas renders live as you edit. Exports are a still PNG, or an MP4 or WebM video at 480p to 4K for up to 30 seconds, with no watermark. An embed code puts the live gradient on a site as an iframe, and the page URL keeps the settings for sharing. The FAQ allows personal and commercial use with no attribution. The tool is in beta. Index lists the paid Backgrounds Supply library as its own record.
Use it to make an animated gradient hero or video backdrop without design software. Pick a mode, set the brand colors, and export a 1080p or 4K MP4 for video or a PNG for a static hero. For a web page, prefer a short looping video or the iframe embed, and check the file size and the effect on page speed. Respect reduced motion settings with a static PNG fallback. The tool needs a browser, so an agent cannot drive it. Ask the user for the exported file or the share link.
Why it is here. It gives a free, no-account way to make animated gradient backgrounds as PNG, 4K video, or a live embed.
