Lively supports more wallpaper formats than any other free desktop wallpaper application for Windows. From simple GIF loops to full 3D game engine scenes, here is everything you can use to bring your desktop to life.
The most popular type of live wallpaper. Set any video file as your Windows desktop background with full hardware-accelerated playback, seamless looping, and support for virtually every modern and legacy video format.
Lively plays back an extensive range of video formats and codecs, making it the most compatible free video wallpaper application available for Windows 10 and Windows 11. Whether you have a short MP4 clip, a high-resolution WebM animation, or an old AVI file from your archives, Lively handles it natively.
H.264-encoded MP4 files offer the widest hardware decoding support across all modern GPUs (NVIDIA, AMD, and Intel). If you are looking for the highest quality at the smallest file size, H.265/HEVC is an excellent choice for 4K video wallpapers, though it requires a compatible GPU or the HEVC Video Extensions from the Microsoft Store. WebM files using the VP9 codec deliver excellent compression and are commonly found on wallpaper sharing sites and video platforms.
Under the hood, Lively uses the MPV media player backend for high-performance, hardware-accelerated video decoding. MPV leverages GPU acceleration (DXVA2, D3D11VA, NVDEC, VAAPI) to decode video frames directly on the graphics card, which dramatically reduces CPU load and power consumption. This means your video wallpaper runs efficiently in the background without slowing down your system or draining your laptop battery.
For users who prefer an alternative, Lively also supports the VLC media player as a backend engine. VLC brings its own comprehensive codec library, which means it can handle virtually any video format out of the box without requiring additional codec packs. Additionally, Lively supports DirectShow-based playback for legacy video formats, ensuring backward compatibility with older codecs that may not be supported by MPV or VLC natively.
While Lively ships with excellent format support through MPV, some rare or legacy codecs may require additional decoder libraries installed on your system. If you encounter a video file that does not play, installing one of the following codec packs typically resolves the issue:
In most cases, no additional codec pack is needed. The built-in MPV engine handles H.264, H.265, VP8, VP9, and all common audio codecs out of the box.
You can convert any video to an optimized wallpaper format using FFmpeg: ffmpeg -i input.mov -c:v libx264 -crf 20 -an -loop 0 output.mp4. The -an flag strips audio to save file size since desktop wallpapers typically play silently.
Video wallpapers on Windows are incredibly versatile. Some of the most popular categories include nature scenes such as rain on a window, ocean waves, northern lights, and forest streams. Abstract animations featuring particle systems, fluid simulations, and geometric patterns create a modern aesthetic. Cinematic loops from movies, anime, and games bring your favorite media to the desktop. Time-lapse videos of cityscapes, star trails, and cloud formations offer a dynamic yet calming ambiance. Many users also set their favorite music visualizers or equalizer animations as video wallpapers, turning their desktop into an always-on media experience.
Lightweight animated image formats perfect for simple loops, pixel art, and retro-themed desktop backgrounds. Set any GIF or animated WebP as your Windows wallpaper with zero configuration.
GIF (Graphics Interchange Format) is one of the oldest and most ubiquitous animated image formats on the internet, and Lively makes it trivially easy to use any GIF as a live desktop wallpaper on Windows 10 and Windows 11. Simply drag and drop a GIF file into Lively, and it becomes your wallpaper instantly.
GIF wallpapers are an excellent choice for pixel art enthusiasts. The format's limited 256-color palette is perfectly suited to retro-style artwork, 8-bit game animations, and sprite-based scenes. Pixel art GIF wallpapers typically have small file sizes (often under 1 MB) and use minimal CPU resources during playback, making them ideal for low-power devices and laptops.
The format is also popular for meme wallpapers, simple aesthetic loops (such as lo-fi study backgrounds), and minimalist animated patterns. Because GIFs are universally supported across every platform and browser, there is an enormous library of free GIF wallpapers available online through sites like GIPHY, Tenor, and dedicated wallpaper communities on Reddit.
While GIFs are great for simple animations, the format has significant limitations at higher resolutions. Because GIF uses lossless compression with a 256-color palette, a full 1080p GIF animation can easily balloon to 50–100 MB or more. At 4K resolution, file sizes become impractical. GIF also lacks support for semi-transparency (alpha channel), which limits visual effects. For high-resolution animated wallpapers, video formats (MP4, WebM) or WebP are significantly more efficient.
WebP is Google's modern image format that supports both static and animated content. Animated WebP files offer substantially better compression than GIF—typically 25–35% smaller file sizes for equivalent visual quality—while supporting 24-bit color with full alpha transparency. This makes WebP the superior choice for animated image wallpapers when file size and quality both matter.
Lively supports animated WebP natively, so you can use WebP animations as desktop wallpapers with the same drag-and-drop simplicity as GIF files. The format's better compression means smoother playback at higher resolutions with less memory consumption.
Both GIF and WebP wallpapers use less CPU than full video wallpapers for simple, short-loop content. Because these formats are decoded as image sequences rather than video streams, they bypass the video decoding pipeline entirely. For animations under 100 frames with simple graphics, GIF and WebP wallpapers are among the most resource-efficient options available in Lively.
However, for complex animations with many colors and high resolutions, video formats (MP4/WebM) with hardware-accelerated decoding will actually be more efficient than GIF. The crossover point is typically around 720p resolution—above that, video formats are almost always the better choice for performance.
The most powerful and flexible wallpaper type. Lively embeds a full Chromium-based rendering engine, giving you the ability to run complete web applications, interactive visualizations, and data-driven dashboards as your desktop wallpaper.
Lively includes a built-in Chromium (CEF) browser engine that renders HTML5 web content directly on your desktop. This is not a simplified HTML viewer—it is a full, modern web browser engine that supports HTML5, CSS3, ES6+ JavaScript, WebGL, WebGL2, Web Audio API, Canvas 2D, CSS animations and transitions, CSS Grid, Flexbox, and virtually every modern web standard. If it works in Google Chrome, it works as a Lively wallpaper.
This means web developers and designers can create desktop wallpapers using the exact same tools and technologies they already know: Visual Studio Code, React, Three.js, p5.js, D3.js, GSAP, Anime.js, or plain vanilla HTML/CSS/JavaScript. There is no proprietary format to learn and no special toolchain required.
The embedded Chromium engine includes full WebGL and WebGL2 support, enabling GPU-accelerated 3D graphics directly on your desktop. Libraries like Three.js, Babylon.js, and PixiJS work out of the box, allowing you to create wallpapers with real-time 3D scenes, particle systems, volumetric lighting, post-processing effects, and more. WebGL wallpapers leverage your GPU for rendering, keeping CPU usage minimal while delivering visually stunning results.
One of Lively's most popular features is direct Shadertoy URL support. Simply paste any Shadertoy.com URL into Lively, and it will render the shader as your desktop wallpaper in real time. Shadertoy hosts thousands of community-created GPU shaders ranging from abstract fractal visualizations to photorealistic ocean simulations and ray-marched 3D scenes. This integration gives you instant access to an enormous library of GPU-powered wallpapers without downloading any files.
Lively provides a powerful JavaScript API called LivelyProperties that lets wallpaper creators expose custom controls to end users. When a user right-clicks a wallpaper and opens its customization panel, they see sliders, color pickers, dropdown menus, toggles, and text inputs that the creator has defined. These controls send real-time values to the wallpaper's JavaScript code, allowing users to personalize the wallpaper without editing any code.
For example, a particle system wallpaper might expose controls for particle count, color palette, speed, size, and gravity. A clock wallpaper might let users choose between 12-hour and 24-hour formats, pick a font, and adjust colors. The LivelyProperties API makes HTML5 wallpapers deeply customizable and user-friendly.
Because HTML5 wallpapers run a full JavaScript engine, they can fetch live data from the internet and display it dynamically. Popular examples include wallpapers that show real-time weather conditions, live clocks with world time zones, system resource monitors (CPU, RAM, GPU temperature), news tickers, cryptocurrency prices, Spotify now-playing information, and calendar integrations. The possibilities are essentially limitless—if you can build it as a web page, you can run it as a desktop wallpaper.
HTML5 wallpapers also support mouse and keyboard interaction on the desktop. Users can click, hover, scroll, and type directly on the wallpaper surface, enabling interactive experiences like desktop-embedded games, interactive art installations, and utility widgets.
Create an index.html file with your wallpaper code, add an optional LivelyProperties.json file to define user controls, then drag the folder into Lively. Your HTML5 wallpaper is ready. Check the Lively documentation for the full LivelyProperties API reference.
Pure GPU-rendered visuals written in GLSL (OpenGL Shading Language). Shader wallpapers are some of the most visually stunning and resource-efficient wallpapers you can run, because all rendering happens directly on the graphics card with zero CPU involvement.
GLSL (OpenGL Shading Language) shaders are small programs that run directly on your GPU. A fragment shader computes the color of every pixel on screen for every frame, generating visuals entirely through mathematics. This means shader wallpapers have no textures, no video files, and no image assets—every pixel is calculated in real time from pure math. The result is infinitely scalable, resolution-independent visual art that looks crisp at any display size, from 1080p to 8K.
Shader wallpapers can produce an astounding variety of visuals: fractal geometry (Mandelbrot, Julia sets), fluid simulations, fire and plasma effects, procedural landscapes, ray-marched 3D scenes, abstract color flows, geometric patterns, audio-reactive visualizations, and much more. The mathematical nature of shaders means they can be parameterized—a single shader can produce thousands of different looks by changing just a few numerical values.
Lively integrates directly with Shadertoy.com, the world's largest community of GPU shader creators. With over 80,000 published shaders, Shadertoy is an inexhaustible source of desktop wallpaper content. To use any Shadertoy shader as your wallpaper, simply copy its URL and paste it into Lively. The shader will render in real time on your desktop at your monitor's native resolution and refresh rate.
Popular Shadertoy categories for wallpapers include ocean and water simulations, cosmic and space scenes, abstract fluid dynamics, geometric kaleidoscopes, and procedural nature scenes (clouds, terrain, auroras). Many shaders respond to mouse input, allowing you to interactively control the viewpoint or parameters by moving your mouse over the desktop.
Shader wallpapers are among the most efficient wallpaper types because they run entirely on the GPU with zero CPU overhead. There are no video frames to decode, no image sequences to load, and no JavaScript to interpret. The GPU simply executes a small mathematical program for each pixel, which is exactly what GPUs are designed to do at maximum efficiency.
On modern dedicated GPUs (NVIDIA GTX/RTX, AMD Radeon RX), even complex shaders typically use less than 5% GPU load. On integrated GPUs (Intel UHD, AMD Vega), simpler shaders run smoothly at 30+ fps with negligible impact on system performance. Shader wallpapers also have a tiny memory footprint—the entire program is usually just a few kilobytes of code.
Lively's LivelyProperties system works with shader wallpapers too. Wallpaper creators can expose shader uniform variables as user-facing controls—sliders for speed, zoom, and complexity; color pickers for palette selection; toggles for enabling or disabling visual effects. Users can tweak these parameters in real time and see the results instantly on their desktop, making each shader wallpaper endlessly customizable.
Run full game engine projects as your desktop wallpaper. Lively supports both Unity and Godot engine exports, enabling interactive 3D scenes, advanced particle systems, physics simulations, and fully realized virtual environments as live desktop backgrounds.
Lively can run exported Unity projects directly as desktop wallpapers. This means anything you can build in Unity—3D landscapes with dynamic weather, particle-heavy visual effects, interactive character scenes, architectural visualizations, procedural terrain generators, physics sandboxes—can become your live desktop background on Windows.
Unity wallpapers leverage the full power of the Unity rendering pipeline, including real-time lighting, shadows, post-processing effects (bloom, ambient occlusion, color grading), and physically based rendering (PBR) materials. The result is desktop wallpapers with visual quality that rivals modern video games.
To create a Unity wallpaper for Lively, build your Unity project as a standard Windows executable, then import the build folder into Lively. Lively embeds the Unity application window behind your desktop icons, manages its lifecycle (pausing when applications are fullscreen or when the laptop is on battery), and provides the same performance controls as any other wallpaper type.
Lively also supports Godot Engine exports as desktop wallpapers. Godot is a free, open-source game engine that has gained significant popularity for its lightweight runtime, intuitive scene system, and GDScript programming language. Godot wallpapers are typically smaller in file size and use fewer system resources than Unity equivalents, making them an excellent choice for users who want interactive 3D wallpapers without heavy resource consumption.
Godot 4.x wallpapers benefit from the engine's Vulkan-based rendering pipeline, offering modern graphics features including global illumination, volumetric fog, and GPU-based particle systems, all running as your desktop background.
One of the most exciting aspects of game engine wallpapers is interactivity. Because Unity and Godot projects can process mouse and keyboard input, your desktop wallpaper can respond to user interaction in real time. Click to spawn particles, hover to influence physics objects, scroll to change the time of day, or type to trigger animations. This level of interactivity transforms your desktop from a passive background into an active, engaging environment.
Both Unity and Godot wallpapers use GPU-accelerated rendering (DirectX 11/12, Vulkan, or OpenGL depending on the engine configuration). Lively's smart performance management ensures these wallpapers pause automatically when you launch a fullscreen game or application, run at reduced frame rates when the desktop is not visible, and respect battery-saver settings on laptops. This means even resource-intensive 3D wallpapers have minimal impact on your actual workflow.
Lively Wallpaper is an independent open-source project and is not affiliated with, endorsed by, or sponsored by Unity Technologies or the Godot Foundation. Unity is a trademark of Unity Technologies. Godot is a project of the Godot Foundation.
Turn any web URL into a live desktop wallpaper. Stream video content, display web applications, or render any online content directly on your desktop—no file downloads needed.
Lively can stream video content directly from URLs and display it as your desktop wallpaper in real time. Simply paste a video URL—from YouTube, Vimeo, or any direct video link—and Lively will stream and render the content on your desktop. This means you can set a live YouTube video, a looping Vimeo clip, or any other web-hosted video as your wallpaper without downloading the file first.
This feature is particularly useful for content that updates regularly, such as live streams, webcams, and continuously updated video feeds. You can watch a live feed of the International Space Station, a nature webcam, or a city skyline stream, all as your desktop background.
Beyond video, Lively can render any web URL as a desktop wallpaper. This opens up a world of possibilities: set a live weather radar map as your wallpaper, display a real-time stock market dashboard, render a web-based art installation, show a live transit map of your city, or even use a web-based productivity tool as an always-visible desktop layer. Any website that works in a modern browser can become your wallpaper.
One of the biggest advantages of URL wallpapers is convenience. There is nothing to download, convert, or manage. You paste a URL, and Lively handles the rest. This is especially valuable when you find interesting content online and want to quickly set it as your wallpaper without going through a download-convert-import workflow. It also means your wallpaper content stays up to date automatically—if the source content changes, your wallpaper changes with it.
URL wallpapers require an active internet connection to stream content. For offline use, consider downloading the video or web content first and using it as a local video or HTML5 wallpaper instead.
