What is an animated background?
An animated background is a moving gradient that loops behind your content instead of sitting still. You'll also hear it called an animated gradient background, a moving background, or a looping video background. Same idea every time: soft blobs of color drift across the frame, add depth, and give the eye something alive to rest on without pulling focus from the words or product in front of it.
This tool builds one from a mesh gradient. Each color you pick becomes a glowing point of light, and those points slide between positions on a loop. Slow it down for a calm, ambient feel, or speed it up for energy. The result is a clean, modern animated background that reads well full-screen or shrunk down behind a headline.
You can drop it almost anywhere: a website hero, a landing page, a presentation slide, a YouTube intro, a podcast cover, or the background of a reel. Export it as a video, set it to loop, and it plays on repeat with no visible restart. If you want a still version of the same look, the mesh gradient generator makes the static image.
Where a moving background earns its spot.
Anywhere a flat color feels dead, a looping background adds life. Here's where creators reach for one most.
Website heroes
Set a looping video background behind your headline and CTA. It adds motion to a landing page without a heavy stock video.
Presentations
Drop an animated background onto a title slide or section break. It makes a deck feel designed instead of default-template plain.
Video intros
Open a YouTube video or course lesson on a moving gradient, then layer your logo and title on top.
Reels & stories
Export a vertical 1080x1920 loop and use it as the base layer for a reel, a story, or a quote post.
Live streams
Run it as a starting-soon or be-right-back screen in OBS or Streamlabs so the frame never goes static.
Product mockups
Frame a screenshot on a soft animated gradient for a launch clip, then layer your product shot on top.

Make an animated background in four steps.
Pick a preset or your colors
Start from a preset like Purple Waves or Ocean Blue, or set your own palette. Each color becomes a soft blob of light in the gradient.
Set the motion
Use the speed slider to make it drift slow or fast, and set the loop length from 1 to 10 seconds. Hit space to reshuffle the layout.
Choose your size
Pick landscape 1920x1080, square 1080x1080, or vertical 1080x1920 so it fits a website hero, a feed post, or a reel.
Export the MP4
Hit export and Krumzi renders your looping animated background as an MP4, ready to drop onto a site, a slide, or a video timeline.
MP4 out of the box. GIF in one extra step.
The exported loop drops straight onto a website, into a slide set to autoplay, or onto a Premiere, CapCut, or Final Cut timeline as a background layer.
The MP4 you get
A looping clip up to 1920x1080, encoded with H.264 so it plays everywhere and stays small. Hit export, Krumzi renders it, and the file lands in your downloads. No watermark, no signup.
Need a GIF background?
Export the MP4, then run it through a free converter like ezgif or CloudConvert. We render video on purpose: the gradient stays smooth, and an MP4 is a fraction of a GIF's file size at the same quality.
Looping on a website
Embedding the background on a site? Use the MP4 in a video tag with autoplay, muted, loop, and playsinline. It behaves like a looping GIF at a tenth of the weight, so your page still loads fast.
Common questions
Frequently asked questions
What is an animated background?
An animated background is a looping gradient that moves behind your content instead of sitting still. People also call it an animated gradient background, a moving background, or a looping video background. It adds depth and life to websites, presentations, video intros, and reels without distracting from the foreground.
Is the animated background generator free?
Yes. It's free, there's no signup, and the export has no watermark. You get a looping MP4 up to 1920x1080. For higher resolutions, longer clips, and full brand control, design your background in the full Krumzi app on a paid plan.
How do I make a purple animated background?
Open the Purple Waves preset in the gallery, or set your own purple palette in the color picker. Adjust the speed and loop length, hit space to reshuffle the layout until you like it, then export. The same steps work for a blue, green, pink, or any other colored animated background.
What formats does the tool export?
The tool exports an MP4 encoded with H.264, which plays everywhere and keeps the file small. If you specifically need a GIF, run that MP4 through a free converter like ezgif or CloudConvert. We use video because the gradient stays smooth and an MP4 is a fraction of a GIF's size at the same quality.
Can I use an animated background as a video background on my website?
Yes. Export the MP4 and drop it into a video tag with autoplay, muted, loop, and playsinline set. It plays on repeat like a looping GIF at a tenth of the file size, so your page still loads fast.
What resolution can I export?
Up to 1920x1080. Choose landscape 1920x1080 for websites and YouTube, square 1080x1080 for feed posts, or vertical 1080x1920 for reels, stories, and TikTok. Pick the size before you export so it fits where it's going.
Can I use these animated backgrounds on commercial websites?
Yes. Backgrounds you make here are cleared for commercial use. You can put them on client work, paid landing pages, product launches, and ads with no attribution required.
What's the best length for an animated background loop?
Five to ten seconds works well for most uses. Shorter loops can feel repetitive, and a slower speed makes even a short loop read as calm and continuous. This tool goes up to ten seconds, which is plenty for a website hero or an intro.
Do I need to sign up or install anything?
No. There's no account to create and nothing to install. Pick a preset or your colors, set the motion, and export. The MP4 is free and yours to use right away.
