How to use Merge JPGs
- 1. Add the photos to combine. Add two or more JPGs, such as before.jpg and after.jpg, in the order you want them to appear in the final composite.
- 2. Choose the layout and background. Select Layout as Side by side or Stacked, then set a Background color to fill any gaps left when the images differ in height or width.
- 3. Download the merged image. The tool arranges all the input photos into one merged.jpg according to your layout choice. Download it for a comparison graphic, a collage strip or a combined social post.
When to use Merge JPGs
Merge JPGs combines several photos into a single image, arranged side by side or stacked vertically. It replaces opening a design tool just to line up two or more pictures when all you need is one straightforward combined file.
- Building a before and after comparison. You want to show a renovation, edit or transformation in one image instead of two separate posts. Merging before.jpg and after.jpg side by side makes the contrast immediately visible.
- Creating a simple product comparison graphic. You are comparing two products or color options for a listing or review. Merging their photos side by side produces one clean comparison image without opening design software.
- Making a quick photo strip. You want several snapshots from an event stacked into one vertical strip, similar to a photo booth print. Stacking the images in order gives you that strip directly.
- Combining screenshots for a bug report. A bug report needs two screenshots shown together to illustrate a state change. Merging them side by side into one image keeps the report compact and easy to follow.

About the Merge JPGs tool
Merge JPGs runs as plain JavaScript in your browser tab, with no server behind it. Combine multiple JPGs side by side or stacked into one image. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JPG Tools section, 145 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Layout and Background color, and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
