Frequently Asked Questions

The cropped image is saved as a PNG file, which preserves all quality with lossless compression. PNG also supports transparency if your original image had a transparent background.
X is the horizontal distance in pixels from the left edge of the image, and Y is the vertical distance from the top edge. These represent the top-left corner of your crop selection in the original image's pixel coordinates.
The rule of thirds is a composition guideline that divides the frame into a 3×3 grid. Placing your subject at the intersection points of these lines typically creates a more visually balanced and appealing image.
Yes. The cropper supports touch events, so you can drag to select the crop area on phones and tablets. For precise control on mobile, use the coordinate input fields instead.
No. The tool only reads your image in the browser — it never modifies your original file. The cropped version is a new file that you download separately.

About Image Cropper

The Image Cropper lets you select a region of an uploaded image and download just that crop. Supports free-form and aspect-ratio-locked cropping — perfect for profile photos, thumbnails, and social media images.

How to Use

  1. Click Upload Image to load an image.
  2. Drag to draw the crop region, or enter exact coordinates.
  3. Optionally lock an Aspect Ratio (e.g. 1:1 for square, 16:9 for widescreen).
  4. Adjust the selection handles to fine-tune the crop area.
  5. Click Crop & Download to save the cropped image.

How It Works

The image is displayed in the browser with an interactive selection overlay. When you confirm the crop, the selected region coordinates are used to draw that portion of the image onto a new canvas, which is then exported as PNG.

Example

Crop a team photo to a 400×400 square for a profile picture: upload the photo, select 1:1 aspect ratio, center the crop on the subject's face, download the square PNG.
