Aseprite

Overview

Aseprite is a drawing application designed entirely around the constraint that every pixel is placed deliberately. There is no anti aliasing unless you ask for it, no smoothing, no resampling behind your back, and the pencil puts down exactly one pixel of exactly the colour you chose. For sprite work, tile sets, icons and any art style where the grid is the point, that discipline is the whole value.

Animation is built into the document rather than bolted on. A frame timeline sits under the canvas with layers running across it, cels can be linked so a repeated frame is edited once, tags name and group frame ranges as separate animations with their own playback direction and speed, and onion skinning shows the surrounding frames behind the current one at reduced opacity so motion can be judged while it is being drawn.

The palette tooling is what separates it from a general raster editor. Indexed colour mode with a working palette, palette editing with ramps and sorting, colour replacement across the whole sprite, shading modes that move a pixel along a defined ramp rather than blending toward an arbitrary colour, and the dithering brushes for the gradient work that indexed art depends on. Tile map mode treats the canvas as a grid of reusable tiles that update everywhere at once when edited.

Export is aimed squarely at the engine on the other side. Sprite sheets write out in packed, horizontal, vertical or grid arrangements with a metadata file describing every frame, tag and slice, animated formats export directly, layers and tags can be split into separate files, and a scripting interface automates repeated export configurations. The command line runs the same export without opening the interface, which makes it usable inside a build process.

Key Features

• Pixel accurate drawing with no unrequested anti aliasing or resampling
• Frame timeline with layers, linked cels and per frame duration
• Animation tags naming frame ranges with their own direction and playback speed
• Onion skinning showing surrounding frames behind the current one
• Indexed colour mode with full palette editing, ramps, sorting and replacement
• Shading mode moving pixels along a defined colour ramp rather than blending freely
• Tile map mode where an edit to a tile updates every instance at once
• Rotsprite rotation and pixel perfect stroke correction for clean lines
• Sprite sheet export in several arrangements with a frame and tag metadata file
• Scripting interface and command line export for use inside a build process

What Changed in This Build

• Faster canvas rendering on very large sprites and long timelines
• Tile map editing improved with better selection and replacement tools
• Additional export arrangements and metadata fields for engine import
• Interface scaling corrected on high density displays

Installation Notes

• Work in indexed colour mode if the target is a constrained palette, converting afterwards rarely gives the result you wanted.
• Use linked cels for held frames rather than duplicating them, editing a held pose once instead of six times is the difference on a long animation.
• Set up your export configuration once and save it, the command line can then run the same export inside a build.

Before You Start

Read the notes above before running setup. Most of the problems people write in about are covered there, and almost all of them come down to an older version of the same software still being installed, a graphics driver that predates the release, or a security suite quarantining part of the package mid install.

There is no archive password on this or any other entry in the library. If something you downloaded elsewhere claims to come from here and asks for one, it did not come from here. Nothing on this site is behind a survey, a shortener or a countdown either.

If the entry does not match what the page describes, say so on the contact page and include the version string from the release details table. Reports naming a specific version get checked first because the checker can reproduce them straight away.
