Open Image Cropper →1. Choose this workflow
Keep a rectangular area of an image using source-pixel coordinates. X and Y locate the upper-left corner; width and height define the retained area.
2. Prepare your input
Read the source dimensions. Enter the upper-left X and Y and a positive width and height wholly inside the image.
3. Follow a worked example
For a 120 × 80 picture, x=20, y=20, width=40 and height=40 produce a 40 × 40 PNG.
4. Check the result
Download and open the saved copy in your usual viewer. Compare it with the example and original: check dimensions, order, orientation and legibility where applicable. Extract ZIP exports and inspect their members. Keep your original until the output is checked.
5. Why is my crop rejected?
Coordinates must be whole pixels and the rectangle must stay inside the source. Width and height must be positive. Cropping removes surrounding pixels; it does not remove or replace a background.
6. Recover from an error
Read the file-type, size and processing limits on the tool page. An extension alone does not prove a file is valid. Try a small supported file or re-export from the source app. Protected or corrupt documents may need an authorized replacement. A successful click alone does not prove the saved copy is usable.

Start with a small example and check the result before using your own data.
