Merge Images
Join two or more images side by side, stacked, or in a grid, with a gap and background colour you choose, and download one PNG or JPG.
Merge Images: The images are placed on one canvas in the order you set. With matching sizes on, every image in a row is scaled to the shortest one's height (or, stacked, to the narrowest one's width), so nothing is enlarged and the edges line up; off, each keeps its own size and the alignment decides where it sits. Runs 100% locally in your browser with zero server file uploads.

Same height scales every image to the shortest one in a row, so nothing is enlarged; turn it off to keep the original sizes. The images are combined in your browser and never uploaded.
Side by side, stacked, or a grid
Side by side suits before-and-after pairs and comparisons; stacked suits long screenshots and step-by-step instructions; a grid suits a set of product shots or a contact sheet. A small gap of 8 to 20 pixels separates images clearly without wasting space.
For a designed layout with borders and rounded corners, use the photo collage maker; to cut an image apart instead, split image.
A worked example
A 1200 × 800 photo and a 600 × 900 photo side by side with matching sizes on: both are scaled to the shorter height, 800 pixels, so the second becomes 533 × 800, and with a 10-pixel gap the result is 1743 × 800.
How to use it
- Choose two or more images, and put them in order.
- Pick side by side, stacked, or a grid, and set the gap, alignment, and background.
- Download the merged image.

Frequently asked questions
Can the background be transparent?
Yes, for PNG: tick Transparent, and any space not covered by an image stays see-through. JPG has no transparency, so it always uses the background colour.
How large can the result be?
Up to 16,384 pixels on a side, the largest size most browsers can draw; turning on matching sizes usually keeps it well under.
Does it lose quality?
Images are only scaled down, with high-quality smoothing, and PNG keeps every pixel exactly; JPG adds light compression.
