What Is a Merge Images?

Merging images puts several pictures into a single file — handy for before-and-after pairs, photo strips, collages, and comparison shots that need to travel as one attachment.

This tool loads each image onto a shared canvas and lays them out three ways: a horizontal row, a vertical column, or a grid with a column count you choose. Rows take the height of their tallest image and columns the width of their widest, so mismatched sizes are centred with background padding rather than stretched and distorted. A gap slider adds even spacing, and you can set the background colour that fills both the gaps and any padding.

The combined result exports as a single PNG. All compositing happens locally with the Canvas API, so your images are never uploaded and large batches stay fast.

Frequently Asked Questions

How are differently sized images handled?
Each row or column matches the largest image in that line; smaller images are centred with background padding so nothing is stretched.
Can I add space between images?
Yes. Set a gap in pixels and pick a background color that fills the gaps and any padding.
What layouts are supported?
Horizontal (a row), vertical (a column), or a grid where you choose the number of columns.
