About the Tool

This tool inputs two sets of images, and stitches them side by side to create a single image.

It resizes the second image to match the first one's height while preserving aspect ratio.

It creates the pair based on the image names (without file extensions).

How to Use

1. Upload images to both Set 1 and Set 2

2. Images will be paired by filename (without extension)

3. Set 2 images will be resized to match Set 1 heights

4. Images will be stitched side by side

5. Download all stitched images as a ZIP file

How it works

  1. Upload Set 1 and Set 2 images.
  2. Images pair by filename (without extension); Set 2 is resized to Set 1 height.
  3. Stitch side by side and download the ZIP.
