What image formats are supported?

The tool supports JPEG, PNG, WebP, TIFF, GIF, and BMP formats.

Can I add padding to only one side of the image?

Yes, you can use the individual top, bottom, left, and right padding fields to add space to specific edges.

How does the blur effect work?

The tool takes the edges of your original image, extends them into the new canvas area, and applies a Gaussian-style blur to create a smooth, bokeh-like background.

Is there a limit to how much I can extend the image?

You can add up to 500 pixels of padding to each side of the image.

Can I change the color of the blurred background?

Yes, you can use the Background Overlay Color option to blend a specific color with the blurred background and adjust its opacity.
