- Press “Resize”, then download the result.
Keeping the aspect ratio
When you set only the width, the height is calculated automatically so the proportions stay fixed, and the reverse when you set the height. A percentage applies to both dimensions, so 50 produces an image half as wide and half as tall.
Shrinking is better than enlarging
Reducing an image keeps it sharp, while enlarging stretches existing pixels and makes it softer. If you need a bigger image, start from an original with higher resolution.
Frequently asked questions

A maximum of 12,000 pixels per side is allowed to keep the browser stable.
