Split an image into tiles
Divide one image into a grid, preview the crop and tile sizes, then download each tile or a ZIP of the set.
The numbers show each tile’s position in the source image. They do not determine how a social platform will arrange posts.
Still JPG, PNG or WebP · Up to 20 MiB and 24 megapixels. Images are not uploaded for processing.
Split preview
Choose an image to preview the grid and tile dimensions.
How do I split an image?
- Choose or drop one still JPG, PNG or WebP image.
- Choose a preset such as a 3 × 3 or 4 × 4 grid, or set the number of columns and rows yourself.
- Set the crop ratio, output width for each tile and file format. Check the preview, then select Split image.
- Download tiles individually or select Download all as ZIP.
Choose a crop ratio and tile size
Crop ratio sets the area kept before splitting. When you choose a ratio, the image is cropped from the center. Output width sets the pixel width of each downloaded tile; its height is calculated in proportion. The crop ratio describes the full image area, not each tile.
For example, a square image split into a 4 × 4 grid produces square tiles. A three-across layout produces portrait tiles. To choose a different crop position first, use the Image cropper, then split using the original image ratio.
Keep original pixels does not enlarge the image. When dimensions do not divide evenly, adjacent tiles can differ by up to 1 px. A custom output width may enlarge a tile, but it cannot add detail to the source.
Each input is limited to 20 MiB and 24 megapixels. Rows and columns can each be 1–6, for up to 36 tiles. A custom tile width is 64–2,048 px; the longest edge is limited to 4,096 px and all output tiles together to 24 megapixels. If the output files exceed 100 MiB in total, reduce their size or choose JPG.
Frequently asked questions
Can I keep a transparent background?
Choose PNG to keep transparent areas from the original. JPG fills transparent areas with white. Animated images and SVG are not supported.
Do the numbers show the order for an Instagram grid?
No. They show each tile’s position from left to right and top to bottom. Social platforms can crop, arrange or display images differently, so preview them on the platform before posting.
Why did my previous downloads disappear after I changed a setting?
Changing a setting clears the earlier results so they cannot be mistaken for output from the new settings. Check the preview and select Split image again.
Are my photos uploaded?
No. Reading, splitting and creating the ZIP happen in your browser. Images are not kept after you refresh or leave the page.
Split one image into tiles and check every edge
Back to toolChoose the grid before exporting
Set the number of columns and rows from 1 to 6 each, for up to 36 tiles. Presets such as 3 × 3 and 4 × 4 are quick ways to start; you can also choose a horizontal strip or a custom grid. I would decide where the important subject and text sit before choosing the grid, so a line does not cross the part people need to read.
The tool numbers tiles from left to right, then top to bottom. File names keep that position, such as image-01-r1-c1.png. Treat those numbers as labels for the source layout. A social app can crop or reorder posts in its own grid, so preview the individual files in the destination before publishing.
Separate the overall crop from each tile’s size
Crop ratio controls the full area kept before the grid is divided. When you choose a ratio, this tool crops the source image from the center. Tile output width is a separate setting: it sets the width of each downloaded tile, and height follows its proportions. A square crop does not make every tile square unless the grid and source dimensions also line up that way.
For example, a 3,001 × 3,001 image divided into 3 × 3 tiles produces widths of 1,000, 1,000, and 1,001 pixels across each row. The height is divided the same way. If a size cannot be divided evenly, adjacent tiles differ by at most 1 pixel.
| Tile position | Output dimensions |
|---|---|
| Row 1, column 1 | 1,000 × 1,000 px |
| Row 1, column 2 | 1,000 × 1,000 px |
| Row 1, column 3 | 1,001 × 1,000 px |
Inspect what crosses each grid line
The preview shows the centered crop and where every tile begins. Check faces, labels, and narrow borders around each grid line. If the source has a clear subject area that should not be cropped from the center, adjust it first with the image cropper, then split using the original image ratio.
Choose “Keep original pixels” to avoid enlarging a tile. You can also choose 320, 640, or 1,080 pixels per tile, or enter a custom width from 64 to 2,048 pixels. A custom width may enlarge the tile, but it cannot add detail to the source.
Choose PNG or JPG for the tiles
PNG keeps transparency from the original image. JPG fills transparent areas with white. Choose the format the destination accepts, then open a few downloaded tiles to confirm that the edges and background look right.
Select Download all as ZIP when you want one archive with the numbered files. Individual downloads are also available. If you want to arrange several separate photos into a designed layout rather than divide one image evenly, use a photo collage maker.
Check the input and output limits
The input must be a still JPG, PNG, or WebP file no larger than 20 MiB and 24 megapixels. Rows and columns can each be 1–6. Each output tile is limited to 4,096 pixels on its longest edge, and the combined tiles are limited to 24 megapixels and 100 MiB. If you reach an output limit, reduce the custom width or use fewer rows and columns.
Images are read, split, and packaged in your browser, not uploaded for processing. A page refresh or leaving the tool clears the current image and results, so download the files you need before closing the page.
Questions about splitting an image
Do the tile numbers match a social media posting order?
They only show positions in the source image, read left to right and top to bottom. The destination platform may crop images to fit its grid or display them in a different order. Check the files in that platform before posting.
Why did my previous tiles disappear after changing a setting?
A settings change clears the previous results so they cannot be mistaken for tiles made with the new settings. Check the preview and select Split image again.
