How to Split an Image Into 4
- Upload a JPG, PNG, or WebP image
- It starts as an even grid, 2 across and 2 down — 4 pieces
- Drag any split line to move it, or type its exact pixel position in Fine-tune
- The pieces are cut as you go — download them individually or once as a ZIP
How This Split Works
The tool opens with a 2 × 2 grid, giving four quarters. Both dividing lines can be moved independently, so the four pieces do not have to be the same size.
Features
- Even 2 × 2 quarters cut as soon as the image loads
- Move the vertical and horizontal lines independently
- Pieces named by row and column so the order survives
- Download the four pieces separately or as a ZIP

| Single-image hard cap | 100 MP | 100 MP; the 80 MP total cap can block first |
| Pieces per split | Up to 144 | Up to 144 |
| Encoded input warning | 100 MiB | 40 MiB |
| Encoded input block | 250 MiB | 100 MiB |

Large dimensions can exhaust browser memory before encoded file size looks large. ToolkitFree checks dimensions and estimated working memory before processing.
Frequently Asked Questions
How do I split an image into 4 equal parts?
Upload the image and keep the default 2 × 2 grid. The four quarters are cut as soon as the lines are in place, so there is nothing to submit. If the width or height is an odd number, the leftover pixel goes to the first piece, so no two pieces differ by more than one pixel.
Can the four parts be different sizes?
Yes. Drag either dividing line, or type an exact pixel position for it. This is how you cut a picture that is made of four differently sized pictures stitched together.
What are the four files named?
Pieces are named by row and column, so photo.png becomes photo-r1-c1.png, photo-r1-c2.png, photo-r2-c1.png and photo-r2-c2.png. Row 1 is the top row and column 1 is the left column.
Can I split into more than four parts?
Yes. Change the row and column count in Fine-tune, or use Add line to place extra dividing lines wherever you need them, up to 144 pieces in total. The pieces are re-cut as you change them.
