Cropping lets you remove unwanted borders or focus on a specific part of an image. This tool uses precise pixel coordinates — enter the starting X and Y position (top-left corner of the crop area) and the desired width and height. This is ideal for developers or designers who need to extract a specific region at exact dimensions. The cropped image is produced in the same format as the source.

How to use

Click 'Choose Image' and select the image you want to crop.
Enter the X and Y coordinates of the crop starting point, and the desired crop width and height in pixels.
Click 'Crop' and download the cropped image.

FAQ

What do the X and Y coordinates represent?

X is the horizontal distance in pixels from the left edge of the image to the start of the crop area. Y is the vertical distance from the top edge. So X=0, Y=0 starts the crop at the very top-left corner of the image.

What happens if the crop area extends beyond the image boundaries?

The crop is clamped to the actual image dimensions. If you enter an X + Width that exceeds the image width, the crop width is automatically reduced to fit. The same applies to Y + Height. This prevents empty areas in the output.

Can I crop to a specific aspect ratio?

Yes, by calculating the dimensions manually. For a 16:9 crop starting at X=0, Y=0, set Width to your desired width and Height to width × 0.5625 (e.g. Width=1920, Height=1080). There is no built-in aspect ratio lock for cropping in this tool.

What formats are supported for cropping?

JPEG, PNG, and WebP images up to 100MB are supported. The output format matches the input format.

Is there a visual crop selector instead of coordinates?

This tool uses coordinate-based input for precision. If you prefer a visual drag-to-crop interface, a desktop application like GIMP or Preview (Mac) offers an interactive crop selection. This tool is optimised for cases where you know the exact pixel coordinates of the region you need.

Is the cropping done in my browser or on a server?

Cropping runs entirely in your browser using the Canvas API. Your images are never uploaded to any server.
