Image & Photo Tools
Image Splitter (Grid & Carousel)
Cut an image into a grid of tiles — for Instagram carousels, photo mosaics or sprite sheets.
Privacy
Your images never leave your device. Files are decoded and redrawn by your own browser using the Canvas API, so nothing is uploaded, queued or logged.
Tips
- For an Instagram carousel, use 3 panels and post them in order — the app stitches them into one panorama as the viewer swipes.
- For a 3×3 profile mosaic, upload the tiles in reverse order. The grid fills right to left, bottom to top.
- Dimensions that do not divide evenly leave a few pixels unused at the right and bottom edges. Crop to an exact multiple first if that matters.
Frequently asked questions
Why do my carousel panels show seams?
Instagram compresses each panel separately, so gradients can band slightly at the joins. Using PNG and avoiding smooth gradients across the seam reduces it.
