Split image into a grid online

Slice a photo into an equal grid of tiles. Set rows and columns, then download the pieces.

What is an image splitter?

An image splitter (also called a picture splitter or photo divider) is a tool that divides a single image into multiple smaller images arranged in a grid. Upload any photo, choose how many rows and columns you want (up to 10 each), and the tool splits the image into equal-sized cells. You can then preview each cell and download them individually or all at once as PNG files. Unlike manual cropping, image splitting creates a uniform grid in one step — ideal for Instagram grid posts, photo puzzles, thumbnail extraction, and design prototyping.

Image splitter features

Split any photo into a grid of smaller images.

  • Flexible grid

    Choose from 1 to 10 rows and 1 to 10 columns to create the perfect grid.

  • Live grid preview

    See the grid overlay on your image before splitting to ensure accurate cuts.

  • Individual cell previews

    Preview each split cell as a thumbnail before downloading.

  • Download individual cells

    Download specific cells one by one, or download all cells at once.

  • PNG export

    Each cell is exported as a high-quality PNG preserving image details.

  • Browser-based

    All processing happens locally — no uploads, no accounts, no limits.

How to split an image into a grid

Split a photo into equal parts in a few simple steps.

  1. Upload your image

    Select a PNG, JPEG, WebP, or GIF file from your device.

  2. Choose grid size

    Set the number of rows and columns (up to 10 each).

  3. Preview the split

    Check the grid overlay on your image and review each cell thumbnail.

  4. Download cells

    Download individual cells or all cells at once as PNG files.

Tips for splitting images

Get the best results when dividing your photos into grids.
  • 01

    Choose the right grid

    A 3×3 grid works well for Instagram posts. Use 2×2 for simple quadrants or 4×4 for detailed splits.

  • 02

    Use high-resolution images

    Start with a large image so each cell retains good quality after splitting.

  • 03

    Check composition

    Make sure important content isn't split across cell boundaries by adjusting your grid size.
