Cropping an image involves trimming or modifying its outer edges to enhance framing or composition, direct the viewer’s attention to the subject, or alter its size or aspect ratio. 

In MockoFun you can trim image easily. Here are the main types of photo cropping : 

Aspect Ratio Cropping: To change aspect ratio of image involves cropping an image while maintaining a specific aspect ratio, such as 4:3, 16:9, or square. It ensures that the width-to-height ratio remains consistent, which is useful for maintaining visual harmony or meeting specific layout requirements.

Freeform Cropping: The freehand cropping allows users to select an arbitrary area of an image to crop, without constraints on aspect ratio. This provides maximum flexibility for cropping images to specific shapes or sizes based on individual preferences.

Centered Cropping: The center crop image involves removing equal amounts of content from the edges of an image to center the subject or focal point. It can help draw attention to the main subject and create a balanced composition.

Subject-based Cropping: The perfect crop focuses on cropping an image to emphasize or highlight a particular subject or object within the frame. It involves adjusting the crop to ensure that the subject remains prominent and visually appealing.

Rule of Thirds Cropping: This technique involves dividing the image into a grid of nine equal parts using two horizontal and two vertical lines, then placing the main subject or points of interest along these lines or at their intersections. Cropping based on the rule of thirds helps create a visually pleasing composition and balance in the image.

Content-aware Cropping: The smart cropping utilizes advanced algorithms to automatically detect and preserve important elements within an image while cropping. It intelligently analyzes the content of the image to ensure that key features or subjects are retained, even after cropping.
