Make Image Grids Before Publishing Comparison Cards

Introduction

Image grids make comparisons easier. Instead of sending four separate screenshots, you can place them into a single visual card for a pull request, bug report, product note, or social post.

The Image Grid Maker is for clean, simple arrangements rather than full design work. It helps when equal sizing and scanability matter more than decoration.

Real-world scenario

You are comparing desktop, tablet, and mobile screenshots of a page. A grid lets reviewers see layout differences at a glance before opening the full images.

Example

Workflow:

1. Resize images to comparable dimensions.
2. Choose a grid layout.
3. Keep spacing consistent.
4. Export the grid.
5. Compress the final card for sharing.

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

Mixing wildly different sizes. Normalize dimensions before making the grid.

Using too many images. Dense grids become unreadable quickly.

Forgetting labels. If context matters, label the source images before combining them.

Practical QA pass

View the final grid at the size it will appear in chat, docs, or a social post. If details are too small, split into multiple cards.

For QA screenshots, keep the order consistent: before/after, desktop/mobile, or input/output. A clear order saves more reviewer time than a dense grid with every possible state.

If each image needs detailed inspection, link the originals next to the grid so reviewers can zoom into the source files.

Before sharing the grid

Check whether the grid needs labels, arrows, or a short caption. A clean visual layout can still be confusing if the reader cannot tell which item is before, after, input, output, desktop, or mobile.

For social cards, preview the grid after platform compression. Thin text and small UI controls may need fewer columns or larger source crops.

If the grid compares versions, use consistent crop boundaries. Changing both the content and framing at the same time makes it harder for reviewers to understand what actually changed.

Publishing boundary

Before posting a grid to a product recap, changelog, or social card, check that each image still has enough detail after resizing. Dense comparison grids can become unreadable on mobile, especially when screenshots contain small UI text. Export one test image and preview it at the final display size before building the whole set.

Adjust spacing before exporting every variant.
