How to Change the Background of a Photo on iPhone
Change a photo's background on iPhone in two steps: remove the background with AI, then place your subject on a new color, scene or design.

Changing a photo's background is really two jobs: cutting out your subject, then putting it on something new. On iPhone the first step now takes one tap with AI. Here's the full workflow.
Step 1: Remove the background
With Erase Spark
- Open Erase Spark and choose Remove Background.
- Pick your photo — a person, pet or product.
- The AI detects the subject and removes everything behind it.
- Save the cut-out to your Photos.

Step 2: Add the new background
Once you have the cut-out, you can place it on anything:
- A solid color — clean and modern, great for profile pictures.
- White — the standard for product photos.
- A new scene — a beach, a city, a studio backdrop.
- A design — flyers, thumbnails, posters and social posts.
Most design and story apps let you add a background color or image and layer your saved cut-out on top.
Make the new background believable
A pasted subject looks fake when it doesn't match its new world. Check:
| Element | What to match |
|---|---|
| Light direction | If the sun comes from the left in the subject, it should in the background too |
| Color temperature | Warm indoor light on a cool blue backdrop looks off |
| Perspective | Eye-level portrait on a top-down background won't match |
| Sharpness | A blurred background behind a sharp subject looks natural; the reverse doesn't |
| Shadow | Add a soft shadow under feet or products so they don't float |
Shortcut: replace only part of the background
You don't always need a full swap. To change one element — a grey sky, a bin, an ugly wall sign — use AI replace and describe what should appear instead, like "a blue sky with soft clouds".
Try it on your own photos
Erase Spark gives you a one-tap cut-out plus AI replace for partial background changes. Free to download on iPhone and iPad.

Yes. Remove the background, then place the subject on a white canvas — the standard look for product listings.
