- Click "Download PNG" to save it.
FAQ
How is this different from cropping?
Cropping cuts off part of the image to match a ratio, but this tool never cuts anything โ it adds padding instead, so the entire original image is preserved.
What's the difference between letterbox and pillarbox?
Letterbox bars are added top and bottom when fitting a wide image into a taller/square ratio; pillarbox bars are added left and right when fitting a tall image into a wider ratio. This tool automatically picks whichever applies based on the image's shape.
Is the image uploaded to a server?
No. All processing happens using your browser's Canvas API โ the image is never sent to a server.
