How to add a background to a photo after removing the original
First remove the old background to get a transparent PNG, then place that PNG over a new color, gradient, or photo and export the result.
To add a background to a photo, you do it in two steps. First you cut out the subject so the old background turns transparent, which gives you a PNG with a see-through area. Then you put that cutout on top of whatever you want behind it, a white fill, a brand color, or a different photo, and save the combined image. The cutout is the hard part. Once you have a clean transparent PNG, dropping a new background behind it takes a minute in almost any editor.
Why do you need a transparent PNG first?
A photo straight off your phone has the subject baked into its background. You cannot just slide a new color behind it, because there is no empty space back there. Every pixel is already filled.
Removing the background fixes that. It deletes the pixels around your subject and leaves them transparent, which most editors show as a gray and white checkerboard. Save that as a PNG and the transparency travels with the file. A JPG cannot hold transparency, so always export as PNG at this stage.
Once you have that PNG, the subject floats on nothing. Anything you put on a layer underneath shows through the empty area. That is the whole trick.
How do you add a solid white or color background?
This is the easiest case and the one most shops need. Open your transparent PNG in an editor that supports layers. Add a new layer below the cutout and fill it with the color you want.
For a hex brand color, paste the exact code into the fill tool instead of eyeballing it. That keeps your product shots and social posts consistent. Then flatten the layers and export. Marketplaces usually want pure white, which is the hex value FFFFFF.
- Open the transparent PNG.
- Add a new layer and move it below the subject.
- Fill that layer with white or your brand color.
- Flatten and export as JPG or PNG.
How do you add a gradient background?
A gradient is a smooth blend between two colors. It reads as a little more polished than flat color and works well behind people for profile pictures or behind products for ads.
The steps match the solid color version. Add a layer below your cutout, pick the gradient tool, choose two colors, and drag across the canvas to set the direction. A soft top to bottom fade is a safe default. Keep the colors close in tone so the subject still stands out.
How do you put a photo behind your subject?
Swapping in a real scene, a beach, an office, a plain studio wall, takes more care, because two photos rarely match on the first try. Place your new background photo on the bottom layer and your cutout on top.
Then check three things. Size: scale the subject so it sits naturally in the scene instead of looking pasted on. Light direction: if the background light comes from the left, your subject should not be lit from the right, or the eye notices. Color: a quick tweak to brightness or warmth on the cutout helps both photos feel like one shot. Spend a minute on the edges too, since stray pixels show most against a busy photo.
Where does BGbust fit in this workflow?
BGbust handles step one. It removes the background and gives you a clean transparent PNG, which is the part people get stuck on. The free in-browser mode runs on your device, so private photos and ID shots never get uploaded to a server.
BGbust does not composite the cutout onto a new photo for you. After you download the PNG, you add the background in any layered editor, such as Photopea in the browser, Canva, Preview on a Mac, or Photoshop. The honest version is: BGbust does the cutout, you place it over whatever background you choose. A free account gives you 4 removals for the life of the account. Pro is 12 dollars a month for unlimited removals and cleaner edges on hair and fur, which matters most when you drop a person onto a detailed photo.
Frequently asked questions
Can I add a background without removing the old one first?
No. The old background fills every pixel, so there is no empty space for a new one. You have to cut out the subject to create transparency, then place a background behind it.
What file type keeps the transparent background?
PNG. A JPG flattens transparency into white, so export your cutout as a PNG and only switch to JPG after you have added the final background.
Does BGbust let me drop my photo onto a new scene?
BGbust removes the background and exports a transparent PNG. To place that cutout onto a new photo, open it in a layered editor like Canva or Photopea and put the new image on the layer underneath.
How do I match my brand color exactly?
Use the hex code for your color in the fill tool rather than picking by eye. That keeps the same shade across every product shot and post.
