Split Images Before Building Carousels or Grid Assets

Introduction

Sometimes one image is too dense for the place it needs to go. A long diagram, screenshot, or visual note may work better as several panels in a carousel, tutorial, or grid.

The Image Splitter helps divide one image into smaller pieces before publishing. It is especially useful when the source already has a clear left-to-right or top-to-bottom reading order.

Real-world scenario

You have a tall process diagram for a social post. Instead of shrinking it until the text becomes unreadable, split it into three panels and publish them as a carousel.

Example

Before splitting:

1. Crop extra margins.
2. Decide the number of rows or columns.
3. Check whether text crosses panel boundaries.
4. Split the image.
5. Preview the panels in order.

Processing is handled in the browser for this tool based on the current public implementation. Avoid entering sensitive images unless you have reviewed the implementation.

Common mistakes

Splitting through text. Move the crop or panel count so labels stay readable.

Forgetting platform aspect ratios. Carousel platforms may crop each panel differently.

Losing order. Name outputs clearly when sequence matters.

Practical QA pass

Open the split panels in the same order users will see them. If a panel lacks context, add labels or use fewer splits.

For tutorial content, each panel should carry one clear step. If users need to jump backward to understand the current panel, the split may be too aggressive.

Before publishing the panels

Name the exported files in reading order and preview them in the target platform. Some platforms reorder uploads, crop previews, or show the first image as the cover card.

If the split is for a carousel, make sure the first panel explains what the viewer will get from swiping through the rest.

For diagrams, avoid splitting through arrows, labels, or numbered steps. If a split line cuts through the logic of the image, users will have to reconstruct the meaning from separate panels.

Preview the exported sequence as a reader, not only as the editor.

Publishing boundary

For carousel posts, export one panel first and preview it on the target platform before splitting the entire source image. Cropping rules, safe margins, and text size differ across Xiaohongshu, Instagram, LinkedIn, and docs pages. If the first panel is not readable on mobile, adjust the source layout before generating every slice.

Number panels when order matters.
