How does this tool work?
Expand or reduce the canvas around an image without resizing its content. The file stays on your device throughout processing and is not uploaded to a server.
Import a PNG, JPEG, or WebP image, then set the width and height of the new canvas. Choose where the image should sit inside that space and select either a background color or transparency. The image keeps its own dimensions: only the surrounding canvas is expanded or cropped. Check the preview before downloading the result.
