How to split an image into a grid

Upload a PNG, JPG, or WebP sprite sheet.

Choose a grid, then optionally enable image positioning and drag the sheet under the fixed lines.

Select PNG, JPG, or WebP output and adjust quality when available.

Download all split assets as a ZIP file.

Split a sprite sheet into rows and columns

Use a preset such as 3 by 3 or enter custom column and row counts for an evenly divided image grid. This works with square, wide and tall sheets. The grid follows your settings; it does not detect individual objects or automatically find the edges of sprites with irregular spacing.

Align the source image and export transparent tiles

If the artwork does not line up with the grid, enable image positioning and move the source beneath the fixed lines. Preview the tile boundaries before downloading. PNG is a useful choice for sprite artwork with transparent pixels; JPG removes transparency, and WebP transparency depends on browser export support.

Download one sheet as a set of image files

The ZIP contains the pieces cut from the currently selected sheet. This is one-image-to-many-files processing, not batch processing of several sheets. Splitting happens locally without sending the sheet to IMGIUM's servers. Keep your source file so you can return to a different grid or offset later.

Image grid splitting questions

Can I split rectangular sprite sheets?

Yes. You can use custom columns and rows for square, landscape, or portrait images.

Can I align an image that does not match the grid?

Yes. Enable Adjust image position, then drag the source image or use the arrow keys. The same offset is applied to the downloaded assets.

Can I choose the output format?

Yes. Split assets can be exported as PNG, JPG, or WebP.

Can I adjust export quality?

JPG and WebP exports include a quality setting. PNG preserves transparency and does not use a lossy quality setting.

Will transparent pixels be preserved?

PNG preserves transparency. JPG does not support transparent pixels. WebP preserves transparency when the browser supports transparent WebP canvas export.

Are the assets downloaded as a ZIP file?

Yes. All split assets are packaged together in a ZIP file.

Are images uploaded to a server?

No. The selected sprite sheet is processed in your browser and is not uploaded to IMGIUM's own servers.

Does the splitter detect each sprite automatically?

No. It divides the image using the rows and columns you choose. For an irregular layout, crop individual areas instead of relying on a uniform grid.

Prepare a sheet or resize the exported pieces

Crop extra borders before dividing a sheet. After splitting, use batch resizing if the exported pieces need a shared output size.
