Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
The 1000 × 800 sample at X = 100, Y = 50, width = 400 and height = 300 produces a 400 × 300 PNG. Its upper-left pixel comes from source coordinate (100, 50).
Method
The browser applies image orientation, validates the rectangle and copies the selected source pixels using Canvas drawImage. Output is not enlarged.
Limits
Static JPEG, PNG and WebP only; animated PNG/WebP are rejected. Maximum input 20 MiB, 40 million pixels and 16384 pixels per side. Source EXIF is not copied; browser color management can change appearance. Cropping does not remove visible private information.
