Two complete pictures on one canvas make a visual review easier to share.

Upload them in the intended order and inspect the viewing scale before judging differences.

## How to use

## Why use this tool

The side by side layout keeps both sources visible without requiring separate windows.


## Before relying on the result

Compare the finished picture with its source. It provides a visual arrangement. Scale, source content and display conditions still affect judgement.
