How to split a sprite sheet
1. Upload one sheet
Open a PNG, JPG, or WebP containing equally sized frames in rows and columns. The image stays in your browser.
2. Match the grid
Enter the number of columns and rows. If the sheet has gutters or an outer border, enter their pixel sizes and check the red cut lines.
3. Export the frames
Download a ZIP of numbered transparent PNG files, plus a JSON manifest with each frame's source rectangle.
