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.

Why Use Image Crop?

  • Visual drag-to-select crop area for intuitive use
  • Manual pixel input for precise control
  • Instant preview of the cropped result
  • No software installation or account required

Common Use Cases

Profile Photos

Crop photos to focus on your face for profile pictures on social media, LinkedIn, or forums.

Product Photography

Trim excess background from product shots for clean e-commerce listings.

Document Scanning

Crop scanned documents to remove scanner borders and blank margins.

Content Creation

Cut out the most important part of a photo for blog headers, thumbnails, or social posts.

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.

Tips & Best Practices

    Click and drag to draw the crop area — the highlighted region shows what you'll keep
  • 2
    Use the numeric inputs for pixel-perfect precision when exact dimensions matter
  • 3
    For social media crops, check the platform's recommended dimensions first
  • 4
    Combine with Image Resizer to crop and then resize to exact dimensions

Frequently Asked Questions

Q Can I crop to a specific aspect ratio?
Currently you can draw any freeform rectangle. For fixed ratios, note the dimensions as you drag or enter exact values.
Q What happens to the cropped-away areas?
Cropped areas are permanently removed from the output. The original file on your device is never modified.
Q Can I undo the crop?
Use the Reset button to go back to the original image and start over with a new crop selection.
Q Does cropping reduce file size?
Yes, since the output contains fewer pixels, the file size will be smaller than the original.
Q What output format is used?
Cropped images are saved as PNG to preserve quality and transparency.
