Crop a PNG Image Online
Open a PNG, adjust the rectangular crop around the content you need, and save the processed result as PNG.
Crop the canvas while keeping PNG
The tool decodes the PNG, removes pixels outside the selected rectangle, and encodes a new PNG file. Transparent pixels that remain inside the rectangle can stay transparent.
Cropping is not lossless byte editing: the file is re-encoded, and metadata or the exact original binary structure may change.
