Hey everyone :waving_hand:

I built PixelForge, an offline browser-based sprite sheet maker and pixel art studio.

It helps you turn individual images or GIFs into engine-ready sprite sheets. You can import frames, pixelate them, pack them, preview animations, and export them for Godot, Unity, Phaser, GameMaker, Construct, Aseprite, or CSS.

What it does:

  • Import images or GIF frames

  • Pixelate and prepare sprites

  • Pack frames into a sprite sheet

  • Preview animations

  • Export Godot-friendly JSON, Phaser JSON, Aseprite JSON, generic JSON, CSS sprites, and GIF

  • Runs 100% offline from a single HTML file

  • No install, no cloud, no telemetry

It is useful for 2D game developers who want a quick workflow from source images to a sprite sheet ready for Godot.

Here is the tool:

I would really appreciate feedback on the workflow, exports, and anything that would make it more useful for Godot developers.
