What is Grid34Sync?
Grid34Sync is a browser-based Instagram grid planner that helps you preview how your posts will look together on your profile before you publish. It accepts images in JPG, PNG, and HEIC formats and produces feed previews (3:4 or 1:1), split carousel slides, puzzle-feed tiles, and custom spacer tiles — all without uploading anything to a server. The tool is free and requires no account.
Key Features
