Tips for resizing images

Leave Keep aspect ratio ticked so the photo isn't stretched. When you change the width, the height updates automatically, and the other way round.

Making an image smaller keeps it sharp. Making it much larger than the original can't add detail, so it may look soft. For websites, 1,200 to 2,000 pixels wide is usually plenty.
