Cut sprite sheets by grid or automatically detect transparent sprite boundaries. Preview every frame, download PNG files as a ZIP, and export metadata for Unity, Godot, JSON, or CSS.
Your artwork stays private
The sheet is decoded, cut and packaged in this browser. It is never sent to our server.
Cut a regular sheet by frame size or row and column count.
Upload a sprite sheet to begin.

Upload a sheet, choose grid or automatic detection, then check every frame before export.
Use Grid when every frame has the same size. Enter the frame width and height, or divide the sheet by rows and columns. Auto detect scans the alpha channel and places a box around each separate opaque region. You can remove false detections before downloading.
The ZIP contains numbered PNG frames. Atlas JSON keeps the original top-left coordinates. Unity JSON converts Y coordinates to Unity’s bottom-left rectangle convention. The Godot file creates AtlasTexture regions, and the CSS export writes dimensions and background positions.
Image pixels, cropped frames and ZIP files stay in browser memory. Closing or refreshing the page clears the working data.
Yes. Auto detect groups connected non-transparent pixels into regions. Adjust the alpha threshold, minimum area and merge distance when shadows or separated parts create extra boxes.
JPG does not store an alpha channel, so its background is opaque. Automatic transparent-boundary detection needs PNG or WebP artwork with transparency.
Use Unity JSON when you need sprite rectangles with bottom-left Y coordinates. Use the Godot .tres export for AtlasTexture regions, then keep the exported file beside the original sheet in your project.
No. Reading pixels, detecting regions, cropping PNG files and creating ZIP or metadata files all happen locally in your browser.
