How cropping differs from resizing
Resizing scales the whole picture, keeping every subject in the frame while changing how many pixels represent it. Cropping discards pixels from the edges, so the composition itself changes.
Both reduce file size, but only cropping lets you remove an unwanted region, tighten the subject, or move to a different shape such as a square.
Why people crop
A tighter frame can put the subject where it belongs, remove distracting elements at the border, or fit a specific display shape. Cropping is also a common way to improve composition after the shot.
Because pixels are removed, the remaining image has fewer of them, so the file shrinks and any later enlargement has less data to work with.
- Tighten the frame around the subject
- Remove unwanted edges or bystanders
- Match a required shape such as 1 by 1
- Cut out a detail to use on its own
Cropping with Filekind
Filekind does not offer a crop tool today. The resize tool scales an image proportionally, which changes size but keeps the entire frame and every subject in place.
Cropping needs an image editor. Once the region is cut, the cropped file can be brought back for conversion or compression in the browser, within the standard 25 MB and 48 megapixel limits. Cropping before resizing usually gives better results too, since the resize then works only on pixels that will actually be shown.
