    Before and after

    Canvas size changes the frame around your image. Resize Image scales the picture itself. Choose Position to decide which edges gain space or get cropped.

    Reducing this canvas from 480 × 360 to 360 × 240 removes 60 pixels from every edge. Use Resize Image if you want the complete picture to fit instead.

    Before you start

    Canvas size changes the frame, not the image scale

    • Change Canvas Size places the unscaled image on an exact-width and exact-height canvas at the chosen position.
    • Use it for a fixed frame; use Resize Image to scale pixels or Add Image Padding when equal spacing is enough.
    • A smaller canvas cuts off source edges, while a larger canvas shows the selected background around them.
