What Is the IMG369 Image Merger?
Image Merger combines two or more photos into a single image, arranged side by side or stacked vertically. It's built for quick before-and-after comparisons, joining screenshots, or lining up a sequence of photos without opening an editor.
This is a simpler operation than IMG369's Image Collage Maker, and deliberately so: no grid, no equal-sized cells, no cropping to fit a cell shape. Photos join edge to edge in a single row or column, each one scaled proportionally but never cropped, keeping the entire original frame of every photo intact.
How It Works
Each photo is automatically scaled to a matching height (side by side) or width (stacked), then drawn edge to edge onto a single canvas, entirely in your browser using the Canvas API. Nothing is uploaded to a server. Switching between the two layout directions re-scales and redraws every photo instantly, so it's easy to compare both options before deciding which one looks better for a particular set of photos.
Merger vs. Collage Maker: Which One You Actually Want
Reach for the Image Merger when you want every photo's full frame preserved, nothing cropped away, arranged simply in a single row or column, which is exactly right for a before-and-after pair or a short linear sequence. Reach for the Collage Maker instead when you have more photos (up to 9) and want them arranged in an even, gallery-style grid, which requires center-cropping each one to fit its cell. The Merger keeps everything, the Collage Maker trims for a cleaner grid, and which one is right depends entirely on whether losing a bit of each photo's edges to cropping is acceptable for your layout.
Common Uses
Creating a before-and-after comparison image, joining two screenshots that were captured separately, lining up a sequence of product photos, combining a few photos into one image for an easier upload elsewhere, or joining a set of scrolling screenshots into one tall image that reads top to bottom.
Choosing Side by Side vs. Stacked
Side by side works best when the photos are naturally similar in height, portrait shots, screenshots of the same app, product photos taken at the same distance, since matching heights means less relative scaling and a more even-looking result. Stacked works better for photos that are already wide, like landscape shots or panorama-style screenshots, where lining them up by matching width keeps the result from getting awkwardly tall and thin. If a set of photos doesn't clearly favor one direction, try both, the difference is one click and the preview updates instantly either way.
IMG369 vs. Other Ways to Merge Photos
Manually placing photos side by side in Photoshop or a similar editor gives full control but requires calculating alignment and canvas size by hand for each pair. Phone gallery apps occasionally offer a basic side-by-side layout feature, but options for stacking direction and scaling are usually limited or missing. IMG369 scales and aligns automatically based on the photos you upload, in the browser, with nothing uploaded.
| Method | Cost | Photos leave your device | Automatic alignment |
|---|---|---|---|
| IMG369 | Free | No | Yes |
| Manual Photoshop placement | Paid subscription | No | No, manual calculation |
| Phone gallery side-by-side feature | Free | No | Often limited |
Summary
IMG369's Image Merger joins 2 to 10 photos edge to edge, side by side or stacked, scaling each proportionally with nothing cropped away, entirely inside your browser with no upload and no signup. The sections above cover when to use this over the grid-based Collage Maker and how to pick a layout direction; the FAQ below covers photo limits and reordering.
Frequently Asked Questions
Is the Image Merger really free?
Yes. There's no signup, no watermark, and no limit on how many photos you merge. Everything runs on your own device.
Do my photos get uploaded anywhere?
No. Photos are combined using the Canvas API entirely in your browser. Nothing is sent to a server.
What if my photos are different sizes?
Each photo is automatically scaled to match, by height for a side-by-side merge or by width for a stacked merge, so the edges always line up cleanly without stretching or distortion.
How many photos can I merge at once?
Up to 10 photos per merge, combined in the order you upload them.
Can I reorder or remove a photo before merging?
Yes, click the × on any thumbnail to remove it before merging. Upload photos in the order you want them to appear.
