A Free Pixel Art Editor That Runs Entirely in Your Browser

What Is Pixelsito?

Pixelsito is a browser-based pixel art editor for drawing sprites, tiles, icons, and frame-by-frame animations. It runs entirely client-side — your artwork stays in your own browser, there's nothing to install, and there's no account or sign-up required to start drawing. It supports unlimited layers with blend modes and non-destructive effects, multi-frame animation with onion skinning and a dedicated timeline, and export to PNG, animated GIF, or spritesheets ready to drop into a game engine.

How to Create Pixel Art in Pixelsito

Start a new canvas from the File menu and pick a size — small canvases like 16×16 or 32×32 are easiest to learn on, since every pixel placement matters more at that scale. From there:

1. Draw with the pencil, line, shape, and fill tools, picking colors from the palette or the built-in color picker.
2. Organize with layers — separate a character's outline, base colors, and shading onto their own layers so you can adjust each independently.
3. Animate by adding frames on the timeline and using onion skinning to see the previous frame while drawing the next one.
4. Export as a PNG for a single image, an animated GIF to preview or share the animation, or a spritesheet formatted for a game engine.

Features

Layers support opacity, Photoshop-style blend modes, and non-destructive effects (outline, outer shadow, inner shadow) that stay editable rather than being baked into the pixels. The animation timeline includes onion skinning, frame tagging for organizing animation states, and a live preview window. Drawing tools include pencil, eraser, fill bucket with gradient and pattern options, shape primitives, lasso and rectangular selection, an eyedropper, and mirror/symmetry drawing modes. Finished work exports as PNG, animated GIF, or a packed spritesheet, and projects save to a portable .pixelsito file you can reopen later or move between devices.

Who Uses Pixelsito

Indie game developers use it to draw sprites, tilesets, and UI icons without installing desktop software. Students and hobbyists use it to learn pixel art fundamentals — limited palettes, readable silhouettes, frame-by-frame animation — without a learning curve before the first pixel gets placed. Artists use it for fast sketches and mockups when a full desktop editor is more setup than the idea needs. The full toolset scales from a five-minute doodle to a complete animated character sheet.
