How it works
Add one or more images
Set a width, height, percentage, or preset. Keep aspect ratio locked to avoid stretching.
Resize and compare dimensions and file sizes before downloading.
When aspect ratio is locked, the most recently edited dimension controls the resize and the other dimension is calculated for each source. Percentage resizing applies to every image's original dimensions. Turning the lock off fits the image to the exact width and height and may stretch it. Enlarging an image adds pixels, not missing detail. JPEG exports place transparent pixels on white.
A few more useful tools
Good to know
Will resizing make my image sharper?
Reducing dimensions can make files easier to share. Increasing dimensions cannot recover detail that was not in the original.
How does batch resizing handle different shapes?
With aspect ratio locked, each image keeps its own proportions. A fixed width, for example, produces different heights for portrait and landscape photos.
