SpriteFrameCutter

What is this?

A standalone, sprite-sheet-first editor: it focuses on editing the atlas itself (not painting, not a timeline).

Use it to extract, rearrange, swap, and rebuild sprite sheets quickly—then export data for your pipeline.

Why I made it

In image processing software, simply selecting and swapping two tiles often means guides, precise selections, and repeated nudging.
In timeline-based pixel tools, a sheet usually has to be imported as frames first, which is overkill when you just want to reorganize an atlas.
This tool is built around the atlas: click tiles, drag them, and rebuild your sheet directly.

Key features

• Multi-select and mouse-first editing
• Cut/Copy/Paste
• Cross-atlas operations: move sprites between sheets
• Paste modes:
  • Linear paste
  • Keep-formation paste
• Drag-out export: drag selected frames to a folder to generate image files
• Folder pack to atlas: collect images from different atlases into a folder, then right-click to pack them into a new atlas
• Quick animation checking: preview a chosen sequence to verify ordering and timing

Export

• PNG — export a rebuilt atlas image
• JSON — export frame coordinates/metadata
• Godot SpriteFrames .tres — export ready-to-use resources

AI disclosure (more detail)

This project uses Generative AI in a limited way:

• Graphics: the logo started from an AI draft, then was manually pixel-edited and color-index corrected by me. All UI styles except for the logo are manually drawn.
• Text: some UI/help text was drafted with an LLM and then reviewed/edited by me.
• Code: AI-assisted code was used during development, but all released code is reviewed, maintained, and tested by me.
• No AI-generated sounds are used.
