Image splitter
Cut one picture into slides that line up when swiped — or into square tiles for a profile grid. Everything runs in your browser.
Slide sizes per platform
| Platform | Ratio | Slide size | Slides |
|---|---|---|---|
| X (Twitter) | 3:4 | 1200 × 1600 px | 2–4 |
| 4:5 | 1080 × 1350 px | 2–10 | |
| 1:1 | 1080 × 1080 px | 2–10 | |
| 1:1 | 1200 × 1200 px | 2–10 | |
| X (Twitter) | 16:9 | 1600 × 900 px | 2–4 |
Split an image in your browser
An image splitter cuts one wide picture into several separate files that fit back together when they are posted side by side. On X, Instagram or LinkedIn each slide is uploaded as its own image, and because the cuts were made from a single original they line up again as the reader swipes — a panorama that reveals itself piece by piece instead of being squeezed into one small frame.
Drop in a picture and choose how many slides you need. The preview shows the whole composition with the cut lines drawn on top, so you can see straight away whether a face, a logo or a headline is sitting on a seam. Drag the preview to move the motif, or zoom in to change how much of the original is used — the cuts follow along live.
Every slide is exported at the size the platform actually delivers: 1200 × 1600 for the 3:4 slides used on X, 1080 × 1350 for Instagram’s 4:5, 1080 × 1080 or 1200 × 1200 for square layouts. Exporting larger does not help, because the network re-compresses anything above its own dimensions. Files are numbered in reading order, so they upload in the sequence they need to be posted.
Splitting is also useful far away from social media. Cut a long screenshot into readable pages, divide a scanned map or a poster into printable sheets, or break a wide diagram into parts that fit a slide deck. The grid mode turns any picture into square tiles — the layout used for a profile grid, where the tiles are posted from the bottom right so the picture assembles itself as new posts push the older ones along.
The whole thing happens on the canvas in your browser. Your picture is never uploaded, there is no account and no watermark, and after the page has loaded the tool keeps working with the connection switched off. That matters for screenshots of unreleased work, client material or anything else you would rather not hand to a stranger’s server just to cut it in three.
Privacy by design
All processing happens inside your browser. Your files never reach a server — there is nothing to store, transmit or share.

Two, three or four side by side, or a grid of up to four columns and four rows — sixteen tiles from a single picture.
The size the platform delivers: 1200 × 1600 px for 3:4, 1080 × 1350 for 4:5, 1080 × 1080 for square and 1600 × 900 for 16:9. You pick the ratio, the tool does the maths.
Yes, as long as you upload them in the numbered order. Every slide is cut from the same original at the same scale, so the edges match exactly.
No. The picture is cut on the canvas in your browser and never leaves your device — the tool still works offline once the page has loaded.
PNG for screenshots, text and flat graphics, where a hard edge must stay crisp. JPG for photographs, where the file is much smaller and the difference is invisible.
Yes — switch to grid mode for square tiles, or use the dedicated Instagram grid maker, which starts in the 3×3 layout.
