How to use it
- 1
Drop a JPG, PNG or still WebP onto the splitter, choose one from your device or paste it. Nothing is uploaded.
- 2
Choose how many slides you want and a 4:5, 3:4 or square shape. The splitter starts with the slide count that keeps the most of your image and tells you how much each choice keeps.
- 3
Drag the image in the preview to keep your subject in frame, then check each slide in the row underneath.

Download the ZIP, unzip it and add the slides to one carousel in order, starting with slide 01.
Before you export
The splitter keeps source resolution and never invents extra detail. Each tile has the same exact aspect ratio and pixel dimensions. A few edge pixels may be trimmed so the cuts join cleanly. The output is not automatically 1080 pixels wide.
For a design with 1080-wide slides, start with 1080 pixels per slide: three portrait 4:5 slides use a 3240 × 1350 canvas; three tall 3:4 slides use 3240 × 1440; three square slides use 3240 × 1080. A smaller source produces smaller slices. Use the image resizer if you need exact export dimensions.
JPG flattens transparent pixels onto white. PNG preserves them. The upload is limited to 20 MiB and 24 megapixels; the output archive is limited to 64 MiB. Large batches can still take longer on a phone.
A carousel is one swipeable post. For separate posts that form a profile mosaic, use the Instagram grid maker. To arrange several future posts, try the free feed planner.
