Image Merge — Combine Two Images Into One Online
Stitch two images horizontally or vertically, zoom and drag each one to frame it, then export a PNG
Upload two images to start — or press Ctrl/⌘ + V to paste from your clipboard
Free online image merger. Upload two pictures and combine them side by side (horizontally) or stacked (vertically). Each image sits in its own cell that you can zoom and drag to reframe, with anything outside the cell cropped away, so the finished image lines up edge to edge without stray gaps. Handy for before/after comparisons, two-part screenshots, chat log stitching, and product detail shots. Everything runs locally in your browser — your images are never uploaded to a server.
How to combine two images into one
- 1
Add two images
Click or drag an image onto each of the two cells, or press Ctrl/⌘ + V to paste a screenshot straight from your clipboard. Selecting two files at once fills both cells in order.
- 2
Pick a direction
Switch between horizontal and vertical at the top. Horizontal matches both images to the same height, vertical matches them to the same width.
- 3
Zoom and drag to frame
Drag an image to reposition it and zoom with the scroll wheel, a pinch gesture, or the slider below. 100% means the image exactly fills its cell; zoom in to keep just the part you want.

Download the result
Need a specific resolution? Edit the width and height in the top right (for example a 1080 × 1080 square), and hit Auto to go back to the size derived from your images. Then click Download PNG to save.
FAQ
Are my images uploaded anywhere?
No. Merging happens entirely in your browser via Canvas. The images stay on your device and are discarded when you close the page.
Can I paste a screenshot directly?
Yes. Take a screenshot and press Ctrl/⌘ + V on this page — it drops into the first empty cell. When both cells are filled, pasting replaces the one you touched last.
Can I merge images with different sizes?
Yes. Horizontal merging matches both images to the smaller height and vertical merging to the smaller width, so the seam lines up without distorting either image. Zoom and drag to choose which part of each image shows.
What does 100% zoom mean?
100% means the image exactly fills its own cell — that is the default. Above 100% the image is enlarged and anything past the cell edge is cropped; below 100% it shrinks and the exposed area of the cell is filled with white.
Does merging reduce image quality?
Not noticeably. The result is drawn at the source pixel dimensions and saved as a lossless PNG. Only the parts you zoom beyond 100% lose detail, the same way enlarging any image would.
Can I merge more than two images at once?
This tool merges two at a time. To combine more, merge the first pair, download the result, then upload it again alongside the next image.
Can I set the output width and height?
Yes. Type the width and height into the output size fields (up to 10000 px each). Changing the aspect ratio reshapes both cells and the images re-frame themselves inside them, so you may want to drag or zoom to fine-tune. Hit Auto to return to the size derived from the source images.
