About

Split Image Online

Split Image Online is home to Tilesmith, a free tool that cuts images and sprite sheets into pieces and gets them ready for your game, right in your browser.

What it does

• Splits images into a grid of equal tiles, or finds every separate sprite on a sheet by itself.
• Names and organises the pieces, with categories, tags and your own data fields.
• Adds what games need: animation clips with frame timing, autotiling and terrains, pivots, collision boxes and 9-slice borders.
• Edits pixels in a built-in editor, and cleans up sheets by removing backgrounds and recolouring.
• Exports single PNGs, a packed sprite atlas, or ready-made files for Godot 4, Tiled and Unity.

The guide walks through every feature, starting with a one-minute way to split an image.

Private by design

Everything happens on your own computer. Your images are never uploaded, there's no account to create, and there are no ads or tracking. Projects stay in your browser, or in a folder you choose. The privacy page has the details.

Who it's for

Game developers turning a tileset into engine-ready tiles, pixel artists slicing their sheets, and anyone who just needs one image cut into many.

Free, and staying that way

Split Image Online started as a simple image splitter; Tilesmith grew out of it. It's free to use, for personal and commercial projects. If it saves you time, you can buy me a coffee.
