Nine-Grid Image Splitter

Create a 3x3 photo grid for your social media feed: 1. Upload or drag and drop your target high-resolution image. 2. The tool will automatically detect the image and generate a 3x3 split preview. 3. Review the grid to ensure alignment. 4. Click 'Download All' to save the 9 individual image segments, ready to be posted sequentially on platforms like Instagram or Weibo.

This tool uses the native HTML5 Canvas API to process your images directly in your browser. When you upload a file, the tool reads the image dimensions and divides the canvas into a 3x3 grid. Each section is then cropped and rendered into a separate image file. This process is fully local, meaning your photos are never uploaded to a server, ensuring maximum privacy and security.
