Some photographers might consider black-and-white photos to be old-fashioned. Yet, black-and-white image conversion can often enhance photographs with poor lighting conditions. Converting images to black and white is also one of the best retro-editing methods for giving pictures of old subjects a nostalgic look.

The vast majority of image editors include at least basic black-and-white editing options. So, there are plenty of software options for converting images to black and white in Windows 11. This is how you can convert your pictures to black and white in Windows 11 with some freely available apps.
