## Introduction

**Aseprite** is a program to create animated sprites. Its main
features are:

* Sprites are composed by [**layers** & **frames**](http://www.aseprite.org/docs/timeline/) (as separated concepts).
* Supported [color modes](http://www.aseprite.org/docs/color/): **RGBA**, **Indexed** (palettes up to 256
  colors), and Grayscale.
* Load/save sequence of **PNG** files and **GIF** animations (and
  FLC, FLI, JPG, BMP, PCX, TGA).
* Export/import animations to/from **Sprite Sheets**.
* **Tiled** drawing mode, useful to draw **patterns** and textures.
* **Undo/Redo** for every operation.
* Real-time **animation preview**.
* [**Multiple editors**](http://www.aseprite.org/docs/workspace/#drag-and-drop-tabs) support.
* Pixel-art specific tools like filled **Contour**, **Polygon**, [**Shading**](http://www.aseprite.org/docs/shading/) mode, etc.
* [**Onion skinning**](https://www.aseprite.org/docs/animation/#onion-skinning)
