What Sprite Outline Adder does

Sprites without an outline sink into a busy background, and outlining a whole sheet by hand is an evening gone. The Sprite Outline Adder puts a hard-edged outline round every sprite: outside or on its own edge, 1 to 8 px thick, with square, round or no corners, in one colour or in a darker shade of the sprite's own colours.

A sheet is outlined frame by frame, so one frame's outline never reaches into the next, and Make room grows every frame so nothing is cut. A second outline round the first gives a sticker or pickup look. Besides the outlined PNG you get the outline on its own, for a hover or selection highlight in your game, with the sheet's JSON and a Godot 4 SpriteFrames.

How it works

  1. Drop a sprite or a sheet, or several (or try ours, six monsters from Pixel Monsters).
  2. Pick outside or inside, the thickness, the corners and the colour; click your sprite to take one of its colours.
  3. For a sheet, check the frame size it found and keep Make room on so no outline is cut.
  4. Download the outlined PNG, the outline alone, and the sheet's JSON and Godot SpriteFrames in one ZIP.

What you get out

  • Outlined PNG, same size or grown to fit
  • The outline alone, for a hover or selection highlight
  • Sheets: a JSON of where every frame is now
  • Sheets: a Godot 4 SpriteFrames (.tres)
