How it works
Drop in images
Up to 10 at a time, any common format.
Enter a size
Exact pixels, a percentage, or a preset — lock keeps the ratio.
Download each result
Same format, new dimensions.
Set a target width and height — or a percentage — and resize images to exact pixel dimensions. Aspect-ratio lock keeps proportions honest while you adjust one side; presets cover the usual targets like 1920×1080, 1280×720, and square 1080×1080.
Resizing down loses information permanently (which is usually the point); resizing up resamples but cannot add detail. The output keeps the input’s format, so a transparent PNG stays a transparent PNG.
Questions, answered
Leave aspect lock on and change just the width or the height — the other side follows automatically.
