What reviewers and creators should know about this splitter
9grid is not a blank upload box. The grid splitter is wrapped in practical publishing guidance: which source sizes survive Instagram compression, when PNG beats JPG, how reverse posting rebuilds a profile mosaic, and how carousel layouts differ from profile grids. That editorial layer exists so the page remains useful even before you touch the tool.
Everything runs in your browser through the Canvas API. Your photo is never uploaded to a 9grid server for the core split workflow. That matters for client work, unreleased campaigns, and anyone who does not want a free tool to keep a copy of their files.
Use a 3×3 when the finished mosaic should live permanently on your profile. Use a 1×N carousel when the reveal belongs inside one swipeable post. Use taller puzzles when you are planning several connected rows. If you are unsure, start with the size table and mistake list on the homepage, then come back here to export numbered tiles.
