Dividing versus cropping
Cropping keeps one region and produces one image. Dividing cuts an image into a grid and produces several. Put all the pieces back together and you have the original — no content is lost, it has only been taken apart.
Because of that, dividing costs nothing in quality and changes nothing about the picture. It solves exactly one problem: turning a single large image into a set of smaller ones.
How to use this tool
Accepts JPG, PNG and WebP up to 20MB. This is a single-file tool — one image per run.
- 1Upload one image.
- 2Set the number of rows (cuts from top to bottom), between 1 and 10.
- 3Set the number of columns (cuts from left to right), between 1 and 10.
- 4Run it. Each piece is offered for download separately, or all at once as a bundle.
When to cut an image into pieces
The classic case is a social media grid. It needs nine square images posted in order to reassemble into one picture — cutting an image into 3 rows by 3 columns lines up exactly.
The second case is outputting large images in blocks for layout or printing. Posters, long infographics and display panels often need to be printed in tiles and joined; dividing first makes printing each tile straightforward.
The third case is splitting a long image into readable sections. Long chat screenshots and tall infographics are often easier to read on a phone when cut into a few segments.
Watch where the cuts land in a grid post
The most common mistake with a 3×3 post is a cut running straight through the subject. A face or a heading spanning two tiles looks broken once published. The safe approach is to look at the composition first, choose rows and columns that avoid the subject, and crop to a square beforehand if needed.
One practical detail: most platforms leave a small gap between adjacent grid images, so the published result differs slightly from the seamless version you see locally. It is a small effect, but visible if the image contains continuous thin lines or borders.
If the width or height does not divide evenly, some pieces will differ by about a pixel. That is inherent to dividing evenly, not a processing error.
Frequently asked questions
- How many pieces can I make?
- Up to 10 cuts per direction and 100 pieces in total — so 10 by 10 is the ceiling. Beyond that the tool refuses with a message rather than producing a huge pile of files.
- What happens if I set rows or columns to 1?
- A value of 1 means no cut in that direction. Setting both to 1 is not a division at all, so the tool asks you to increase one of them instead of handing back a copy of the original.
- Can the pieces be reassembled?
- Yes. Dividing just extracts pixel regions — nothing is recalculated or recompressed, so putting the pieces back in row and column order rebuilds the original exactly.
- What if the dimensions do not divide evenly?
- Pieces are split on whole pixels, so they may differ by a pixel or so. If the image is so small that a piece would be under one pixel, the tool refuses and suggests fewer rows or columns.
- Can I process several images at once?
- One at a time. The grid needs to suit each image’s composition, so applying one set of rows and columns to a batch has little practical value — this tool is built for a single file.
