Image Splitter

Splitting an image into tiles lets you post a seamless panorama carousel, create a giant grid on your Instagram profile, print a poster across several sheets or prepare sprites and puzzles. Fileopia’s image splitter cuts any picture into an exact grid of equal tiles, crops it to the right shape first, numbers the pieces in the order you need and packs them into a single ZIP. Everything is processed in your browser – the image is never uploaded.

Common uses

• Create a 3×3 or 3×4 Instagram profile grid from one picture.
• Turn a wide panorama into a swipeable 3-slide carousel.
• Print a large poster across several A4 or Letter pages.
• Make jigsaw-style puzzles or classroom activity cards.
• Slice a sprite sheet or banner into separate images.

Tips for best results

• For Instagram profiles, use 4:5 portrait tiles – the grid now displays 3:4 crops of 4:5 posts.
• With “Posting order” numbering, upload file 1 first – it is the bottom-right tile – so the grid lines up on your profile.
• Keep important details away from the cut lines.
• Use PNG for graphics with text and JPG for photos.
• Custom grids go up to 20 × 20 tiles.

How the cutting works

The splitter first decides the overall shape: columns × tile width by rows × tile height. If your image does not match that shape, it is centre-cropped so every tile is exactly the same size with no stretching. Each tile is then drawn from the original full-resolution pixels onto its own canvas and encoded in your chosen format. Because nothing is resized more than necessary, details stay sharp.

Panorama carousels

A 3×1 split turns a wide landscape into three posts that join seamlessly when people swipe through a carousel. Upload the tiles in left-to-right order in a single carousel post. For best results start with an image about 3:1 in shape; otherwise the splitter crops the top and bottom to fit. The same technique works for LinkedIn document posts and for wide banners on other platforms.

Printing large posters

To print a poster bigger than your printer’s paper, split the image into, say, 2 × 3 tiles and print each tile on its own page at full size. Trim the white margins and tape the sheets together from the back. Higher-resolution source images give better results; aim for at least 150 pixels per inch of finished size. The image to PDF tool on this site can combine the tiles into one printable document.
