Free online tool to plan and split images for Instagram grids.

Grid34Sync is a free web-based tool designed for Instagram content creators, social media managers, and marketers who want to visually plan their feed. It solves the problem of manually creating cohesive and aesthetically pleasing Instagram grids by providing tools to easily split single images into multiple posts for carousels or puzzle feeds. The tool allows users to instantly preview how their posts will look in both the newer 3:4 aspect ratio and the traditional square format before publishing. It eliminates guesswork and saves time by generating blank placeholder tiles and providing a visual planner to arrange content for a consistent feed aesthetic. The platform requires no sign-up and operates entirely in the browser.
