Several steps, or a whole batch? Chain this with other tools in a Workflow and run them in one go.
Matching sizes
With Same height on, taller pictures are scaled down to the shortest one, so nothing is enlarged and nothing goes soft. Turn it off to keep every picture at its own size, centred, with the background filling around the smaller ones.
Which format
JPG is smallest for photos. PNG keeps screenshots and text sharp and can keep a see-through background. WebP does both at a smaller size, though a few older apps won’t open it.
Very large results
The combined picture is capped at 60 megapixels and 16,384 pixels on its longest side. Anything bigger is scaled down to fit, and the tool tells you when that happened.
Your pictures stay with you
Everything happens on your own device. Nothing is uploaded, nothing is stored, and you don’t need an account. Close the tab and it’s all gone.
