Background Replacer: how to use it
- Drop in the photo whose background you want to change.
- Choose the New background: a photo of your own, a blurred copy of the original, a solid colour, or one of the soft gradients.
- If you chose a photo, add it in the Background photo box. Then replace and download.
Tips
- Pick a background with light from the same direction as your subject. It is the main thing that makes a swap look real.
- Best edges gives cleaner hair and outlines; Fast is quicker for simple portraits.
- For product listings, the Product Photo Studio adds a shadow and sizes the image for marketplaces.
Background Replacer: what it does and when to use it
The Background Replacer does two jobs in one: a segmentation model separates the subject from its surroundings, then the subject is laid over a new background of your choice. That can be a photo of your own, a blurred copy of the original, a solid colour, or one of the soft studio gradients.
A blurred copy of the original is the most forgiving choice, because the colours and light already match the subject. A new photo looks convincing when its light comes from the same direction and has the same warmth as the light on your subject, and when its perspective suits the shot: a head-and-shoulders portrait needs a background seen from eye level, not from above.
The Fast model is tuned for people; Best edges handles products, pets and objects with finer outlines. Shadows the subject cast on the old background are not carried across, so full-length shots can look like they float. For marketplace product photos, the Product Photo Studio adds a floor shadow and sizes the result for you.
Background Replacer: frequently asked questions
Is the Background Replacer free, and do I need to sign up?
Yes, the Background Replacer is 100% free with no sign-up, no login and no account. The Background Replacer runs its AI model on your own device, so it has no credits, no daily limit and no upload, and saves at full resolution with no watermark. See why it is free.
How do I change the background of a photo?
Open the photo, then choose what goes behind the subject: your own background photo, a solid colour, a gradient, or a blurred version of the original. The AI cuts out the subject on your device and places it on the new background. It is free, with no upload and no watermark.
How do I put a white background on a photo?
Pick a colour background and set it to white. For product photos that must meet marketplace rules, use the Product Photo Studio, which also centres the product and adds a natural shadow.
Why does the new background look fake?
Usually because the light does not match: a subject lit from the left on a background lit from the right never looks real. Choose a background with similar light and colour, or blur it slightly so it reads as out of focus. The Photo Relighter can warm or cool the subject to match.
Can I blur only the background instead?
Yes. Choose the blurred background here, or use Portrait Blur, which has more control over how strong the blur is.
