How to use it
- Click Choose a file and pick a picture, or drop it on the box.
- Choose the Rows and the Tile shape. The grid appears on the picture: the shaded part is left out.
- Move Horizontal position or Vertical position if the grid should show another part of the picture.
- Click Cut the tiles, then download the ZIP. Post the files in the order of their numbers, starting with 01.
How the grid is cut
The grid has three columns and the rows you choose. Each tile has the shape you choose: square, 1 to 1, or portrait, 4 to 5. The page first finds the largest rectangle of the grid's overall proportion that fits the picture, then cuts that rectangle into equal tiles. When the picture is wider or taller than the grid, the spare part is cut away, and the position sliders choose which part stays.
Neighbouring tiles share an edge exactly, so no pixel is lost or copied twice. Where a width does not divide into three equal whole pixels, one column is a pixel wider than the others. Each tile is then drawn at 1080 pixels wide: 1080 by 1080 for a square tile, and 1080 by 1350 for a portrait tile.
The order to post the tiles
The tool numbers the tiles from the bottom right to the top left, so that the first file is posted first. This follows the usual practice for a profile that shows the newest post at the top left. The Instagram help pages that were checked when this tool was made do not state how the profile orders its grid, so look at your profile after the first post and change the order if the picture does not line up.
The tool does not post anything for you, and it does not check the shape Instagram accepts. Keep the same shape for every tile, so that none of them is cropped differently.
Example: a 1200 by 900 picture in a three-row grid
With square tiles and three rows, the grid's proportion is 1 to 1. The largest square that fits the picture is 900 by 900 pixels, so 150 pixels are cut from each side with the horizontal position at the middle.
Each tile is 300 by 300 pixels in the picture and is drawn at 1080 by 1080 pixels. Tile 01 is the bottom right tile, row 3 and column 3, and it is posted first; the file is named 01-r3c3.jpg.
Frequently asked questions
Is my picture uploaded when I cut the tiles?
No. The picture is read by your browser, cut into tiles and written as files on your device. You can check this by turning off your internet connection after the page has loaded and cutting a small picture.
Why do the tile numbers start at the bottom right?
A profile usually shows the newest post at the top left. Posting the bottom right tile first and the top left tile last lines the grid up on the profile. The Instagram help pages that were checked do not state the order, so confirm it on your own profile.
Which tile shape should I choose?
Choose the shape you post. A square is 1 to 1 and a portrait is 4 to 5. Use the same shape for every tile, so the grid lines up and no tile is cropped differently.
Why is one column a pixel wider than the others?
The picture width is often not a multiple of three. The tool cuts the edges to whole pixels so that the tiles fit together exactly, which makes one column one pixel wider when needed.
Can I use PNG files instead of JPEG?
Yes. PNG keeps every pixel exactly but the files are larger. JPEG is smaller and is the usual choice for a photo of this size.
