How do I resize an image without stretching it?

Change only one side and let the other follow the original aspect ratio. This resizer keeps proportions automatically when you fill in just the width or just the height, and it can also resize by percentage or to print sizes in centimetres, millimetres or inches.

How to resize images

Drop one or more images into the box.
Choose to resize by pixels, percentage or a print unit.
Enter the width or height (keep proportions on) and choose the output format.
Download the resized images.
