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

Upscayl is an open-source offline AI tool with a built-in masking module that allows users to remove background from picture while upscaling photos with AI. It offers a one-stop local editing solution that lets you use the masking brush to precisely outline the subject and clean up the background.

How to Remove background from picture

1. Download the software installer from the official website and complete the offline installation.
2. Launch the software and import the photo you want to remove the background from and enlarge.
3. Activate the built-in masking tool in the software’s sidebar and use brush strokes to cover the subject.
4. Click the “Invert Selection” button to automatically erase all background areas not covered by the mask.
5. Adjust the mask edge smoothing parameter, then export the image as a transparent PNG file.

Disadvantages

• There is no optimized batch processing feature; each image must be cut out manually, one by one.
• The cutting-out process relies on manual tracing, which can be time-consuming for subjects with complex, multi-edged outlines.
• The background removal module is only a supplementary feature and is not as professional as dedicated image-cutting software.
• The AI model takes up a significant amount of local disk space and consumes a high amount of computer GPU resources.

This dual-function open-source toolkit integrates AI-powered image enlargement and background removal features, making it ideal for users who need to enlarge photos and remove backgrounds simultaneously within the same offline workflow.

However, its background removal feature lacks dedicated batch processing support, so it cannot efficiently process dozens of photos at once.

ps

• After completing the image cutout, be sure to export the image as a PNG file to preserve the transparent background; the JPG format discards transparency information.
• Use a finer mask brush to trace fine details, such as hair, to improve the final result after removing the background.
• Close other resource-intensive software during the process to prevent lag caused by GPU resource consumption.
