Tiles are named row-col (e.g. tile-1-1) so they reassemble left-to-right, top-to-bottom.

Build a perfect Instagram grid, privately

Slicing a banner into a 3×3 grid by hand is fiddly — one pixel off and the seams don't line up. HeroTools cuts mathematically even tiles with your device's own Canvas, optionally squaring the cells so each post is a clean square. Download tiles one at a time or as a single ZIP, and upload them bottom-right first to rebuild the image on your profile. Nothing is ever uploaded to a server.
