Crop an image with numeric pixel coordinates. The left and top fields define the starting point; width and height define the kept area. The crop is constrained to the source boundaries, which prevents blank or out-of-range output.
How to use Crop Image
- Select an image and note its width and height.
- Enter the left, top, crop width, and crop height values.
- Process the crop, review the preview, and download the selected region.
Things worth knowing
- The origin is the top-left corner at 0, 0.
- Coordinates outside the image are clamped to valid pixels.
- Use a social preset tool when you need a standard platform aspect ratio rather than exact coordinates.
Frequently asked questions
Can I drag the crop box?
The first version uses precise numeric controls. A draggable crop overlay can be added without changing the local-processing model.
Does cropping reduce file size?
Usually, because it removes pixels. The output format and quality also affect the final size.
