Image Splitter
Slice one photo into a rows × columns grid — perfect for Instagram carousels — free
Pick a rows × columns grid, preview the cut lines, then split.
Never uploaded — Everything runs in your browser — your images never leave your device.
The slicing math, made explicit
Pick rows × columns and the tool computes tile width as floor(imageWidth ÷ columns) and height likewise, trimming the remainder symmetrically so every tile stays pixel-identical. Two extras matter in practice:
- Overlap adds N pixels of bleed to adjacent edges — essential for printed puzzles where blade tolerance eats the seam.
- Order naming — files export as
name_r1_c2.png, so reassembly order survives any upload platform that sorts alphabetically.
Output format follows the input when it is PNG or JPEG; WebP sources convert to PNG to keep maximum compatibility.
Slicing built for social media
Cut any image into clean grids for carousel posts, print tiles or puzzle sheets — with overlap control that generic splitters skip.
Grids up to 10 by 10
Choose any rows and columns combination up to 10 each, or tap the 3×3, 2×2, 3×1 and 1×3 presets. The classic 3×3 feeds the nine-tile Instagram grid.
Cut lines before cutting
A preview overlay draws the exact grid over your image before anything is generated, so rows and columns can be adjusted until the seams land where you want them.
Tiles in reading order
Every tile downloads in a single ZIP, named left to right and top to bottom, so posting them in order rebuilds the full picture. The grid math keeps the seams pixel-perfect.

Frequently asked questions
Is my photo uploaded?⌄
No — splitting happens entirely in your browser with the Canvas API. Your photo never leaves your device.
What's this useful for?⌄
Instagram carousel grids (post one wide photo as several swipeable tiles), puzzle-style photo grids, or breaking a scan into printable panels.
Do the tiles line up exactly?⌄
Yes — pixel edges are distributed evenly across the grid so the tiles always cover the whole photo with no gaps or overlaps, even when the size doesn't divide evenly.
Why is my last row slightly cropped?⌄
When the image height isn't divisible by your row count, the remainder is trimmed evenly top and bottom so all tiles keep identical dimensions. Use an image whose height divides cleanly if you need zero loss.

What Is an Image Splitter?
An image splitter cuts one picture into a grid of equal tiles — a technique social media users employ to turn a single large photo into a multi-panel carousel, and a handy way to create puzzle grids or segments for large-format printing. You choose how many rows and columns to cut, up to 10 each, with a classic 3 by 3 preset ready for the well-known nine-tile feed effect. The cut lines are previewed over your image before you commit, and every tile downloads in one ZIP, named in reading order. Each tile is a complete, individually usable image, and the grid math guarantees they line up perfectly when re-posted in sequence. Everything is cut with Canvas in your browser — the source image never leaves your device. It is for social media managers building grid feeds, designers prototyping large prints, and content creators experimenting with tile-based posts.
What this tool can do
- Cut any image into a rows by columns grid of up to 10 by 10 tiles
- Preview the exact cut lines over the image before splitting
- Choose JPEG or PNG output for the tiles, with a quality setting
- Download every tile in one ZIP, named in reading order
- Start from a 3 by 3 preset for the classic nine-grid feed
- Keep the source image in your browser — it is never uploaded
When you'll use it
- Posting one big photo as a 3 by 3 grid that viewers assemble by swiping
- Building a jigsaw-puzzle version of a family picture or design
- Splitting a panorama into panels for a large-format print or wall mural
- Creating a feed-wide storyboard effect from a single artwork
- Prototyping a tile-based layout for a web or print project
Privacy and limits: all splitting happens locally in your browser — nothing is uploaded and no account is required. Tiles are re-encoded from the canvas, so very large photos with extreme grids take a moment to render; starting from a reasonably sized image gives the smoothest experience.
