How to remove a white background with Luminar?

Deleting a white background with Luminar is easy. Simply use the AI-powered Background Removal AI Extension or the Portrait Background Removal AI tool if you are working with a portrait. These tools automatically detect and mask up the subject in your photo and easily remove it with the power of AI.

Can I reverse deleting a white background?

Luminar has an Undo feature that lets you easily reverse your changes.

What are the limitations of removing a white background from an image?

If you want to remove a white background from PNG, keep in mind that it has some limitations and challenges. For example, if the subject is intricate or contains fine details like hair or fur, achieving a precise selection can be more challenging. If the subject was originally photographed with specific lighting and shadows that interacted with the white background, removing the background may disrupt the integrity of the lighting and shadowing, making the subject look out of place in a new background.

Does the photo get smaller or look different when we remove the white background?

When you erase a white background, it doesn't inherently change the size or appearance of the image, but subsequent actions you take, such as resizing, altering the aspect ratio, or applying edits, can lead to changes in how the image looks and behaves.
