NOTE: Pixen is now a paid app in the Mac App Store. Please consider purchasing it if you would like to support future development.
Pixen is an open source pixel art editor designed for working with low-resolution raster art, such as those 8-bit sprites found in old-school video games. With innovative features like a unique color palette system, patterns, layers, and high-zoom support, Pixen packs all the tools pixel artists need in an intuitive, Mac-native interface. Pixen also makes creating frame-by-frame animations fun and easy.
Animations – Create and arrange image frames in the filmstrip view to piece together animations; export animations as animated GIFs or even spritesheets!
Tools – Leverage Pixens wide array of tools when composing pixel art: Pencil, Eraser, Eyedropper, Zoom, Rectangular Selection, Magic Wand, Lasso, Move, Fill, Line, Rectangle, and Ellipse.
Layers – Take advantage of the flexibility layers provide when working with complex pixel art.
Color Palettes – Add and organize commonly-used colors into palettes.
Patterns – Define custom patterns to use while drawing with the pencil, line, or eraser tool (instead of a single pixel).
Custom Backgrounds – Pick a flat, striped or checkered background (or even a custom image) to be drawn beneath the canvas.
Grid + Alignment Crosshair – Let the grid and the alignment crosshair guide you in placing pixels just where you want them.
Preview – While editing at high zoom levels, use the Preview window to view the canvas scaled out; play back animations in the Preview window.
Left and Right Tools – Assign a different tool to the left and right mouse button. For example: pencil on the left; eraser on the right.
Tablet Support – Pixen supports pressure-sensitive drawing tablets and maps pressure to color opacity.
Hotkeys – Customize tool hotkeys to ease the transition from other image editors.
Full Screen – Work with all your favorite tools in full screen mode on OS X Lion.
