What Is Image Crop?
An image cropper lets you remove unwanted parts of an image by selecting the exact region you want to keep. This is one of the most common image editing operations, essential for removing distracting backgrounds, focusing on a subject, or adjusting image composition. The tool provides a visual, interactive rectangle selection that you draw directly on the preview by clicking and dragging. You can also fine-tune the crop coordinates manually by entering exact pixel values for X, Y position, width, and height. All processing happens entirely in your browser for maximum privacy and speed.

Technical Guide
Image cropping uses the Canvas API's drawImage method with source rectangle parameters (sx, sy, sw, sh) to extract a specific region from the source image. The crop selection is implemented by tracking mouse events on the preview area, converting screen coordinates to image coordinates using the display-to-actual scale ratio. The selection rectangle overlay is rendered using CSS absolute positioning with percentage-based coordinates for responsive display. When manual coordinates are entered, they are validated against image boundaries to prevent out-of-bounds cropping. The resulting cropped image maintains the original pixel density within the selected region.
