How do I remove the background of a PNG image in Windows 11?

For anyone trying to remove white background from PNG, unbagrnd is a open-source option worth trying on Windows. It runs the background-removal process locally, so you don't need to upload your images to an online service.

The workflow is fairly simple: download the Windows release from the project's GitHub page, install and open it, then load your PNG image. Let the model detect the main subject and remove the surrounding background automatically. Before exporting, zoom in and check areas such as hair, thin edges, and small details for any unwanted background pixels.

For images with a fairly clean white backdrop, this can be a convenient way to remove white background from PNG while preserving transparency. Export the finished result as PNG rather than JPEG so the transparent background is retained.
