Image merger
Join photos and screenshots vertically or horizontally into one image. Control their order, aligned size, spacing and background color before downloading.
This tool does not send entered values or selected files to a server. Save any results you need before closing the tab.
How to use
- Choose up to eight images and use Earlier or Later to reorder them.
- Choose a direction, aligned side size and gap. Vertical layouts align widths; horizontal layouts align heights.
- Generate, inspect the preview and download in the chosen format.
Worked example
Two 600×400 images merged vertically at 600 px with a 20 px gap produce a 600×820 image.
Method and limitations
Each image keeps its aspect ratio while one side is resized to the chosen size. The other side is rounded to a whole pixel, then gaps are added. Small originals may be enlarged.
Up to eight files, 15 MB each, and 24 million input pixels total. Output is limited to 8,192 px per side and 16 million pixels. Reduce the aligned size if needed.
Frequently asked questions
Does it automatically stitch overlapping screenshots?
No. It places the chosen images in order without detecting overlapping content. Crop repeated areas first if necessary.
