How can I remove background from a photo or picture in bulk?

Windows 10 and Windows 11 come with a built-in program called Paint 3D, which you can use to remove background from picture and perform basic image editing.

Instructions: Open the target image file in Paint 3D, click the Magic Selection tool in the top menu bar, drag to select the subject in the image, click Next to adjust the automatically generated selection, click Finish to remove the background, and then save the processed file in PNG format to preserve the transparency.

Its advantages include: built-in functionality on Windows systems and support for manual fine-tuning of cutout edges

Disadvantages include: the process is entirely manual and supports only single-image processing, with no batch processing support; it performs poorly at recognizing complex or blurry image edges; it is inefficient when processing large numbers of images; and advanced image-cutting adjustment tools are limited.

Notes

• Be sure to save the cropped image as a PNG file; the JPG format discards transparency data.
• Before drawing the selection box, zoom in on the image window to improve the accuracy of the Magic Selection tool.
• If the automatic selection misses details of the subject, use the Add/Subtract Brush tool to manually refine the edges.

This allows you to remove background from picture, making it suitable for everyday, small-batch photo-cutting needs on Windows devices, as well as for quickly creating transparent images for simple design purposes.
