Canvas size without resizing
The image itself is not stretched, scaled, or compressed by the canvas controls.
This is useful when a layout needs exact dimensions but the source artwork should stay intact.
Image Canvas Adjuster
Change one image's canvas size without resizing the image itself. Set dimensions, extension direction, transparency, and download locally.
No image selected
Drop, click, or paste one JPEG, PNG, or WebP image to adjust its canvas.
Tip: paste an image from the clipboard (Ctrl+V).About image canvas adjustment
Canvas adjustment changes the output frame around an image while leaving the image pixels at their original size.
Choose where the canvas grows
A 3x3 direction grid decides which side receives new canvas space.
If the canvas is smaller than the source, the same direction decides which side is clipped.
Transparent or solid background
Transparent output works well for PNG and WebP, while solid backgrounds are useful for JPEG and social assets.
Everything is rendered locally in your browser before download.
