An Image Slicer tool divides a single image into multiple equal rectangular parts (slices) based on a grid defined by rows and columns. It uses your browser's Canvas API to perform the slicing locally — your image never leaves your device. You can then download individual slices or get all slices packaged into a single ZIP file. It's perfect for creating Instagram carousel posts, printing large images across multiple pages, or breaking down graphics for web layouts.

To create an Instagram grid, upload your image and use one of our presets: 3×1 for a 3-post horizontal panorama, 3×2 for a 6-post grid, or 3×3 for the classic 9-square grid. Each slice maintains perfect dimensions so your feed looks seamless when viewed together. Download all slices as a ZIP, then upload them in order to Instagram for a stunning tiled profile effect.

No. This tool operates entirely within your browser using client-side JavaScript. Your image is processed locally via the HTML5 Canvas API and is never transmitted to any external server. This ensures complete privacy and security for your files. The ZIP packaging (when you choose "Download All") is also generated locally using the JSZip library.

The tool supports PNG, JPEG, WebP, GIF, and BMP formats for upload. All slices are downloaded as PNG files to preserve quality with lossless compression. If you upload a GIF, only the first frame will be processed. SVG files are not supported because they cannot be rendered on a Canvas element.

Yes! This tool is fully responsive and works on smartphones and tablets. You can upload images from your photo library, adjust rows and columns with touch-friendly sliders, preview the grid, and download individual slices or the complete ZIP package — all from your mobile browser. The interface adapts automatically to smaller screens for a smooth experience.

You can slice an image into up to 10×10 = 100 slices using the range sliders. However, we recommend keeping individual slice dimensions above 50×50 pixels for practical use. If your image resolution is too low relative to the grid size, the tool will warn you that slices may be very small. For best results, use high-resolution images when creating many slices.

Each slice is extracted at the original image resolution — there is no quality loss during the slicing process. Slices are saved as PNG files with lossless compression, preserving every pixel exactly as it appears in the original. The preview in the tool is scaled for display purposes, but the downloaded files contain the full-resolution slice data.

The tool uses floor division to ensure all slices have identical dimensions. For example, if your image is 1000px wide and you choose 3 columns, each slice will be 333px wide (1000 ÷ 3 = 333.33, floored to 333). A tiny strip of 1 pixel on the right edge may be excluded. This guarantees perfectly equal slices for seamless grids. To avoid any cropping, consider resizing your image to dimensions divisible by your desired grid count.
