## What it does
- Remove image backgrounds automatically
- Replace backgrounds with colors, gradients or images
- Position cut-out subjects and adjust their colors

## In brief
BgSub uses AI to isolate subjects in portraits, product photos and other images. Its web editor can replace the removed background with a solid color, gradient or another image. Additional tools adjust size, position and mirroring, while automatic color correction and artistic filters help combine the subject with its new background. It suits product imagery, social graphics and straightforward photo composites. The provider states that images are processed without being uploaded. This is a vendor claim, rather than an independent privacy audit. Fine hair, transparent objects and similar foreground and background colors may require closer inspection.


## Limits
Open the web app and select an image, drag it into the editor, or use the available URL or paste option. Inspect the cut-out edges before adjusting the background, position and colors. The checked editor is accessible without signing in. Use images you are entitled to edit.
