Why resize an image?
Resizing lets you change the width and height of an image in pixels. This can be useful for websites, social networks, documents, profile pictures and other services with image dimension requirements.
Reducing image dimensions can also help decrease file size because the image contains fewer pixels.
Keeping the aspect ratio allows you to change the width or height without distorting the original proportions of the image.

Frequently asked questions
How do width and height work when keeping the aspect ratio?
They define a bounding rectangle. The image fits inside without stretching, so one resulting dimension can be smaller than the value you entered.
Can I set both dimensions exactly?
Yes. Turn off the aspect-ratio lock. If the ratio changes, the image will be stretched; crop first to keep its shape.
Does enlarging restore detail?
No. Scaling creates more pixels but does not recover missing image detail.
