Spriteloom

Free tools for making game sprites.

Each one opens straight in your browser. Nothing is uploaded, nothing is stored, and there is no account to make. Pick a tool and start.

How a sprite gets from a generator into your game

  1. Start with whatever you have: a PNG, a sheet, an .aseprite file, or a video clip.
  2. Cut it into frames. On a grid for a sheet, by time range for a video.
  3. Fix the pixels by hand, then tag the frames that make up idle, walk, punch.
  4. Export the atlas and the .tres, and drop both into res://.

What they don't do

There is no auto-fix button

Cleaning up a generated sprite means editing pixels. These tools make that fast. They do not do it for you, and nothing here generates art.

They read .aseprite, they don't write it

Projects save as .fish. Coverage of the Aseprite format has not been audited across versions, so treat opening one as best effort.

Nobody is storing your work

No account, no cloud, no sync. There is a four-second autosave into your own browser, but that is a guard against a stray reload, not a backup. Save the file yourself.
