Technical Specifications & Insights
Cropping is the process of removing unwanted outer areas from an image. This tool renders your image onto an interactive canvas, allowing you to position coordinate pointers. Once you apply the crop, the backend crops the image to the selected area. This is ideal for adjusting photos to fit standard aspect ratios like 1:1 for social media or 16:9 for widescreen headers.
