Example
A 4000 × 1200 beach panorama cut into 3 square tiles for a carousel
A panorama from a week at the shore, beach.jpg, 4000 × 1200 pixels: blue sea, sand, a red-and-white umbrella on the left and a yellow sun on the right. It is going up as a carousel of three photos. Settings: 3 columns, 1 row, Square tiles ticked.
- Three square tiles side by side need a 3:1 picture, so 200 pixels are trimmed from each side and the middle 3600 × 1200 is kept.
- That middle is cut into three tiles of 1200 × 1200, which meet without losing a pixel.
- Select Split image and download beach-1-1.jpg, beach-1-2.jpg and beach-1-3.jpg, named by row and column.
| Picture | Grid | Tiles |
|---|---|---|
| 4000 × 1200 | 3 × 1, square | 3 of 1200 × 1200 (200 px off each side) |
| 4000 × 1200 | 3 × 1, not square | 1334, 1333 and 1333 × 1200 |
| 3240 × 4320 | 3 × 3 | 9 of 1080 × 1440 (3:4, lines up on a profile grid) |
| 4032 × 3024 (phone photo) | 3 × 3, square | 9 of 1008 × 1008 (504 px off each side) |
| 6600 × 5100 (22 × 17 in at 300 dpi) | 2 × 2 | 4 of 3300 × 2550, each a US Letter sheet, landscape |
Three square photos that join back into the whole beach as people swipe through the carousel. Add them in order, beach-1-1, the left tile, first.
How it works
- Drop the picture onto the box.
- Set the number of columns and rows: 3 × 3 for an Instagram grid, 3 × 1 for a panorama carousel.
- Tick Square tiles to cut the picture to the shape that makes every tile square, trimming evenly from both sides.
- Select Split image and download the tiles, named by row and column.
Frequently asked questions
- In which order do I post the tiles on Instagram?
- The files are named by row and column, -1-1 being the top left. A profile grid shows the newest post first, so post them from the last tile to the first: bottom right, then leftwards along the bottom row, and the top left last.
- Will the tiles line up on my Instagram profile?
- Instagram's profile grid shows each post cropped to a 3:4 rectangle, so square tiles lose their sides there and the picture no longer joins up. For a grid that lines up on the profile, start from a picture that is 3:4 itself (for example 3240 × 4320 px) and leave Square tiles off: each of the nine tiles is then 3:4 as well. Square tiles suit a panorama cut 3 × 1 and posted as one swipeable carousel.
- Are the tiles exactly equal?
- They are as equal as whole pixels allow. When the width does not divide evenly, a few tiles are one pixel wider, so nothing is lost at the edges.
- Can I split a picture to print as a poster over several sheets?
- Yes. Choose the grid that matches the sheets — 2 × 2 for four sheets — and print each tile full page. Start from as large a picture as you can, as each sheet shows only part of it.
- Can I cut a picture in half?
- Yes: 2 columns and 1 row give a left and a right half, 1 column and 2 rows a top and a bottom half. When the width is odd, the left half is one pixel wider, so the two halves still add up to the whole picture.
- Do the tiles lose quality?
- Each tile is cut from the full-size picture, never scaled. Saved as JPG or WebP, it is compressed again at high quality, which is hard to see; choose PNG for tiles with no further loss, at the cost of larger files.
- Is my picture uploaded, and what are the free limits?
- It is not uploaded: the tiles are cut in your browser. The free plan allows 3 pictures of up to 20 MB per run and 5 runs a day. Pro removes these limits.
