Drop an image into the splitter above and it cuts four pieces in a 2 by 2 arrangement, which is how X lays out a four-image post. Switch to two or three pieces for those layouts instead. Attach the pieces in order and the picture reassembles in the timeline.

Drag any line to move a cut. Tab to a line and use the arrow keys to nudge it one pixel, or hold shift for ten.
Vertical cuts give side-by-side pieces. Horizontal cuts stack them.
The tool picks the rows and columns that keep the pieces closest to square.
A shared strip on each seam, so the sheets can be trimmed and taped.
Each piece is resized to the size this page targets before it is saved.
Your image never leaves your device. Splitting runs in your browser with the Canvas API.
| X single image post | 1600 × 900 px (16:9) |
|---|---|
| X profile header | 1500 × 500 px (3:1) |
| From a 1080 × 1080 square | 4 pieces of 540 × 540 px |
| From a 1080 × 1350 portrait | 4 pieces of 540 × 675 px |
| From a 4000 × 3000 photo | 4 pieces of 2000 × 1500 px |
A post on X can carry up to four images, and X arranges them in a fixed layout that depends on how many you attach. Splitting one picture across those tiles gives you an image far larger than a single attachment, but only if the split matches the layout.
Four images go into a 2 by 2 grid, which is why this preset starts there. Attach them in order and the four quadrants reassemble.
Two images sit side by side, each tile close to 7:8, so a vertical split into two pieces is the match. Three images put one tall tile on the left with two shorter tiles stacked on the right, which is not an even grid: the first image you attach takes the tall position. A plain 1 by 3 cut will not line up with that, so plan the three-image case deliberately rather than expecting an even split to work.
The other thing to design around is the crop. X crops every tile from the centre, so anything near the edge of a piece can disappear in the timeline. Clicking the post shows the full image, but the timeline view is what most people see. Keep subjects and type toward the middle of each piece.
Use the same aspect ratio for every piece in a post. Mixed shapes get cropped unpredictably to fit the layout.
Nothing is uploaded.
A 2 by 2 split fills a four-image post, giving a much larger presence in the timeline than one attachment. Attach the pieces top left, top right, bottom left, bottom right, which is the order the file names are numbered in. Keep detail away from the tile edges.
Two images sit side by side, each tile close to 7:8. Split a comparison down the middle so each state gets its own tile at equal width. Both are cropped from the centre in the timeline, so keep the part that makes the comparison in the middle of each piece.
Charts and dashboards are unreadable when a wide screenshot is scaled into one tile. Splitting into two or four pieces gives each part more room. Export as PNG so axis labels and small text stay legible after the platform re-encodes the upload.
A split image at the top of a thread reads as one large graphic while still being four separate attachments. Since the timeline crops each tile from the centre, design so the centre of each piece carries the message and the edges are background.
Split it into as many pieces as you plan to attach, then attach them in order. A 2 by 2 split matches the four-image layout. A vertical split into two matches the two-image layout. Attach the pieces in reading order and the picture reassembles in the timeline.
Two images sit side by side, each tile close to 7:8. Three images put one tall tile on the left with two shorter tiles stacked on the right, and the first image attached takes the tall position. Four images are arranged as an even 2 by 2 grid.
Every tile in a multi-image post is cropped from the centre to fit the layout. That is why detail near the edge of a piece disappears in the timeline. Clicking the post opens the full image, but the timeline crop is what most people will see.
Four. That is why this splitter tops out at a 2 by 2 grid for the reassembling case. If you need more pieces than that, split into four for the first post and continue in a reply, or use a carousel-style platform instead.
Yes. Mixed aspect ratios get cropped unpredictably as X fits them into the layout, which pulls a reassembled picture out of alignment. An even split gives every piece the same shape, which is the simplest way to keep the tiles consistent.
It is the same platform and the same layouts. Anything written here about tile arrangements and centre cropping applies whichever name you use for it. The split itself is just an image operation, so the pieces work anywhere that accepts multiple attachments.
