About this tool

This tool lets you crop an image down to a specific rectangular region using precise X, Y, width, and height values, with a live preview showing exactly what will be kept — all processed locally with the Canvas API.

How to use it

  1. 1Upload an image.
  2. 2Adjust the X, Y, width, and height fields to define the crop region — the preview updates live with the selected area highlighted.
  3. 3Click "Crop & download PNG" to save the cropped result.

Common mistakes to avoid

  • Setting a crop region that extends past the image's edges — values are automatically clamped to stay within bounds.
  • Forgetting that X and Y start from the top-left corner of the image, not the center.

Use cases

  • Cutting a specific subject or region out of a larger photo.
  • Removing unwanted borders or edges from a scanned image.

Frequently asked questions

Can I crop to a specific aspect ratio like a square?

Set the width and height fields to match your target ratio manually — for a square crop, use equal width and height values.
