Image Splitter

1What is Image Splitter?

Split a single image into a grid of tiles.

Image Splitter is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.

2How does Image Splitter work?

Splitting cuts the image into an R×C grid using exact integer boundaries computed from the original dimensions (remainder pixels are distributed across the edge tiles so nothing is lost). Each tile is cut from the decoded buffer without resampling and delivered as an individual download plus a bundled ZIP when multiple files result.

This is the standard technique for Instagram grid posts, print tiling and slicing long screenshots into sections — tiles reassemble seamlessly because boundaries share pixel edges.

E-commerce teams process entire product catalogs to consistent sizes and weights, which measurably improves load speed and conversion. Content creators and social media managers depend on it for daily platform-ready assets, while students and office teams use it to shrink scans and photos so they fit comfortably inside emails, forms and presentations.
