A grid split can prepare separate pieces for a layout or inspection task. The source dimensions do not always divide evenly by the number of rows and columns, so the edge handling matters.
Image Grid Splitter partitions the image into covering tiles. It includes the leftover pixels rather than dropping them from the last row or column.
Uneven widths are normal
A 400 by 300 image split into three columns and three rows gives nine tiles. Their widths are 133, 133 and 134 pixels across each row, while all three row heights are 100.
Together, those tile areas cover the original 120,000 pixels. A one pixel difference in tile width is expected when 400 cannot be divided into three equal whole pixel widths.
The files are named by row and column. Keep that order if you plan to reconstruct the source or arrange the tiles in another design.
Splitting does not enlarge a picture
Each tile contains its region at source resolution. The operation does not create extra detail or automatically expand every tile to a social platform's recommended size.
You can download files individually or use the browser ZIP. The tool limits the grid to six rows and six columns, and generated bytes remain bounded across all outputs.
If the receiving layout requires identical tile dimensions, crop the source to a suitable divisible size first. Otherwise, that layout may stretch an uneven edge tile and create a seam.
Keep the original and inspect the outermost tiles as well as the centre. Those pieces are where rounding and crop mistakes are easiest to notice. The splitter includes every pixel, but your later placement still determines whether the final arrangement aligns correctly.
