How is the border added?

The tool creates a new canvas larger than the original image by twice the border width in each direction, fills it with the chosen border color, and draws the image centered with an optional rounded-rectangle clip.

Can I use transparent border color?

The color picker does not expose an alpha channel, so the border is always fully opaque. For transparent borders, manually edit the PNG in an image editor after download.

Will the border increase the file size?

Yes — the output canvas is larger than the input image by the border width, so the PNG file will be slightly larger.
