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
- 1Upload an image.
- 2Adjust the X, Y, width, and height fields to define the crop region — the preview updates live with the selected area highlighted.
- 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.
