Removing the background means separating the main subject of a photo — a person, product, or logo — from everything behind it, leaving a clean transparent (or solid-color) background. This is essential for product photos, profile pictures, logos, and any image you want to place on a new background without an ugly box around it.
Doctor PDF offers several detection methods so you can pick the one that cuts your image out best, then download a PNG with a transparent background.
