Image Padding Resizer

Padding grows the canvas rather than covering the picture: every original pixel survives and a band of background is added around it. Set the thickness and the fill here — the same operation supplies the margin a near-square product photo needs to reach a true square.

Frequently Asked Questions About Image Padding Resizer

What is the difference between padding and a border?

Padding enlarges the canvas and leaves the image alone; a border is drawn over the image's own outer pixels and keeps the size.

Can I pad with a transparent background?

Yes, in a format that carries alpha — PNG or WebP rather than JPEG, which fills with a solid colour.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the Padded canvas.

What should I check before using the result?

Open the Padded canvas in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

About this workflow

Padding rather than cropping to reach a frame

When the edges matter — a diagram, a screenshot, a caption — padding keeps them where a crop would remove them. Match the fill to the destination background for an invisible margin.

Before downloading the result

Open the Padded canvas next to the original at full size and check text edges, faces, and flat backgrounds; re-encoding softens detail long before it looks wrong in a thumbnail.
