Image Cropper
Crop an image to an exact aspect ratio (16:10, 16:9, 1.91:1, 1:1, 4:3, 4:5 or 9:16), move the focus point and zoom, then export at the width you need.

Input
Crop an image to an aspect ratio
Output
Choose an image
The crop keeps the largest area of the chosen shape and the focus sliders move it, so the subject stays in frame when a portrait photo becomes a 16:10 cover. Upscaling beyond the cropped area's own pixels only makes the file bigger: the size of the crop is shown so you can tell.

Why crop to a ratio
Layouts that display images at a fixed ratio crop them anyway, usually through object-fit: cover from the centre, which can cut off a face or the important half of a screenshot. Cropping deliberately before upload puts the subject where it belongs. Link previews on social networks use roughly 1.91:1, and many card layouts use 16:10 or 16:9.
Do not upscale
If the cropped area is 600 pixels wide, exporting it at 1280 only adds bytes. Start from the largest original you have.
