Create pixel art animations frame-by-frame — export as GIF or sprite sheet
Last updated: March 2026
The Pixel Art Animator is a free online tool that lets you create frame-by-frame pixel art animations and export them as animated GIFs or sprite sheets — no signup, no download required. Draw on a pixel grid from 8×8 to 64×64, add frames, use onion skinning to see your previous frame, and preview your animation in real time.
Pixel art animation has exploded in popularity, driven by indie game development (over 2,000 pixel art games launched on Steam in 2025 alone) and a thriving online art community. Professional tools like Aseprite cost $20, and free alternatives like Piskel lack features. This tool provides onion skinning, multiple palettes (NES, Game Boy, PICO-8), and GIF export at up to 8× resolution — all running in your browser.
Exported GIFs and sprite sheets work directly in game engines (Unity, Godot, GameMaker), social media posts, Discord emotes, and web projects. All processing happens locally — your art stays on your device.
1. Select a grid size. 16×16 and 32×32 are the most popular for game sprites. Smaller grids animate faster because there are fewer pixels to draw per frame.
2. Pick colors from a palette. Choose from NES (56 colors), Game Boy (4 greens), PICO-8 (16 colors), or Pastel. You can also use the color picker for any custom color. Recently used colors are saved automatically.
3. Draw your first frame. Use the pencil for single pixels, fill for large areas, and the line, rectangle, and circle tools for shapes. The eraser sets pixels back to transparent.
4. Duplicate and modify. Click “Duplicate” to copy the current frame, then make small changes on the copy. This is the core of frame-by-frame animation — each frame is a slightly different version of the one before it.
5. Use onion skinning. Toggle it on to see the previous frame ghosted at 25% opacity behind your current drawing. This is how professional animators keep motion consistent between frames.
6. Preview and export. Hit play to see your animation loop. Adjust FPS (8 is the standard for pixel art). When you are satisfied, export as an animated GIF at 1× to 8× scale, or as a sprite sheet PNG for game engines.
Onion skinning is the standout feature for animation work. Seeing the previous frame while you draw eliminates guesswork and produces smoother motion. Toggle it on and off as needed.
Retro palettes keep your art authentic. The NES palette matches the exact colors available on the original Nintendo hardware. Game Boy gives you the iconic four shades of green. PICO-8 provides the 16-color palette used by thousands of indie games.
Nearest-neighbor scaling is critical for pixel art export. Unlike standard image scaling that blurs pixels, this tool scales with nearest-neighbor interpolation, keeping every pixel crisp and sharp at 2×, 4×, or 8× resolution.
Sprite sheet export arranges all frames in a horizontal strip PNG — the format expected by Unity, Godot, GameMaker, Phaser, and most game engines. Import the sheet, set the frame dimensions, and your animation is ready to use in-game.
