Change an image's size in pixels

Enter the width or height you need (or a percentage) and download the image at its new dimensions, in the same format.

Good to know

Change only one measure to keep the proportion and avoid a stretched image.
With exact measures the image can be distorted if they do not follow the original proportion.
An image is not enlarged unless you ask; enlarging does not add detail.
You can process up to 20 images at once.

How do I resize without distorting the image?

Set only the width or only the height, or use a percentage: the original proportion is kept.

Does reducing pixels also reduce the file size?

Usually yes, since there is less data to store, but the exact size depends on the format and content.
