Canvas de Arte em Pixels & Exportação CSS

Paint crisp 8-bit style sprites directly in your browser and export them as pure-CSS box-shadow art, scalable SVG, raster PNG, or portable JSON. The canvas scales from 8×8 up to 64×64, ships with classic palettes (NES, Game Boy, PICO-8, CGA, Commodore 64, Sweetie 16), and gives you paint, eraser, fill, and eyedropper tools with unlimited undo and redo.

Como usar

Pick a grid size from 8×8 to 64×64. Larger grids give more detail but slower paint speed.
Choose a preset palette or drop any hex colour into the colour picker.
Click the paint, eraser, fill, or eyedropper button in the canvas toolbar — or press P, E, F, I.
Click and drag on the canvas to paint. Use Ctrl+Z e Ctrl+Y to undo and redo.
Pick an export format (CSS box-shadow, SVG, PNG data URI, or JSON), set the pixel size, then copy the code or download the file.

Características

Six grid sizes – 8×8, 16×16, 24×24, 32×32, 48×48, and 64×64 for anything from tiny icons to full sprite sheets.
Seven preset palettes – NES (54 colours), Game Boy, PICO-8, CGA, Commodore 64, Sweetie 16, and a grayscale ramp.
Four drawing tools – paint, eraser, paint bucket (flood fill), and eyedropper with single-key shortcuts.
Smooth drag drawing – Bresenham line interpolation keeps strokes continuous even on small screens.
Unlimited undo and redo – 60-step history with Ctrl+Z and Ctrl+Y keyboard shortcuts.
Four export formats – CSS box-shadow, SVG, PNG data URI, and JSON grid data, each with a live 1:1 preview.
Touch support – works on tablets and phones with native touch and pointer events.
Transparent cells – empty pixels stay transparent in every export format, not painted white.

 Perguntas frequentes

What is a pixel in digital imaging?

A pixel (short for picture element) is the smallest addressable unit of a raster image. Each pixel stores color information — typically red, green, and blue channel values between 0 and 255 — and together a grid of pixels forms a complete image.
How does CSS box-shadow render pixel art?

CSS box-shadow accepts multiple shadow declarations, each with an x offset, y offset, blur radius, spread radius, and color. Setting blur and spread to zero and positioning each shadow on a grid effectively paints individual coloured rectangles from a single 1x1 element — producing a pure-CSS pixel image without any raster data.
What is a limited colour palette and why is it used?

A limited palette restricts an artwork to a small fixed set of colours, often matching the hardware constraints of retro consoles such as the NES, Game Boy, or Commodore 64. Working within a palette creates visual cohesion, evokes a recognisable era, and forces deliberate colour choices instead of arbitrary ones.
What is the flood fill algorithm?

Flood fill is a graphics algorithm that starts at a target cell and spreads outward to every neighbouring cell that shares the same colour, replacing each with a new colour. Most paint-bucket tools use a four-directional flood fill (up, down, left, right) implemented with a stack or queue to avoid deep recursion.
Why are raster and vector pixel art different?

Raster pixel art is stored as a grid of coloured cells (PNG, data URI). Vector pixel art represents each cell as a mathematical shape (SVG or CSS box-shadow) that scales infinitely without losing crispness. Vector output is ideal for web UIs where shape-rendering: crispEdges preserves the blocky look at any zoom level.
