Split Image into Grid

Tiles, remainder pixels and names

You set rows and columns, and the tool divides the image's width and height by those numbers to find each tile's size. When a dimension is not exactly divisible (for example, 1000 px into 3 columns), the last column and last row absorb the leftover pixels, so no pixel is lost and the reassembled image is identical to the original.

Each tile is named by its position in the grid (row × column), which makes reassembly or posting in the right order much easier. All come in a single .zip, avoiding dozens of individual downloads.

• Tile size = dimension ÷ number of rows/columns.
• Last row/column absorbs the leftover pixels.
• No pixel is lost in the split.
• Tiles named by position (row × column).

Mosaic and carousel on Instagram

Example 1, a feed mosaic (3×3): split the image into 3 columns and 3 rows to get 9 tiles. Post them in reverse order (the bottom-right tile first, going up) so that, in the profile grid, they line up and form the complete artwork.

Example 2, a panoramic carousel (3×1): split a very wide photo into 3 columns and 1 row. Posted as a swipeable carousel, the three tiles recreate the feeling of a continuous panorama as you swipe from one to the next.

Sprites, textures and printing

Beyond social media, grid splitting is useful for game development: a sprite sheet (several poses of a character in one image) can be sliced into individual frames. The same applies to texture atlases, when you need the pieces separated.

There is also large-format printing: splitting a poster into tiles that fit an ordinary printer lets you assemble a giant image afterward by taping the sheets. Because the export is lossless PNG, the tiles' quality is identical to the original image.
