About the Change Background Color
Change Background Color fills the transparent areas of an image with something new. It works with cut-out PNG, WebP, AVIF, GIF and SVG files. You can choose a solid color from eight quick swatches or any custom color, a two-color gradient at any angle, or another photo that is scaled to cover the whole frame and can be blurred for a soft, out-of-focus look.
A clean background makes a subject look professional. Online shops often need product photos on pure white, many forms ask for a plain white or blue background, and social posts look better with a brand color or gradient. This tool only fills transparent pixels, so normal JPG photos need their background removed first. The subject keeps its original size and sharpness.

Frequently asked questions
How do I change the background color of a photo?
The photo needs a transparent background first, so remove it with Img Stop's Background Remover. Then open Change Background, add the transparent PNG, choose Color and pick a swatch or a custom color. Press Apply background and download the photo with its new color.
Why does the background not change on my JPG?
JPG images cannot be transparent, so there is no empty area for the tool to fill. The tool changes only transparent pixels. Run your photo through the Background Remover first, which gives a PNG with a clear background, then add that PNG here.
How do I make a white background for a product photo?
Remove the product's background, add the transparent PNG here, keep New background on Color and pick the white swatch. Save as JPG for a small file that most online stores accept. The product stays exactly the same size and in the same position.
Can I put my photo on a different picture background?
Yes. Choose Image under New background and select the photo you want behind your subject. It is scaled to cover the whole image without stretching. Tick Blur background image to soften it, so your subject looks in focus and the scene looks natural.
How do I add a gradient background?
Choose Gradient under New background. Pick Color 1 and Color 2 and move the Angle slider to set the direction, for example 90° for a top-to-bottom blend. Gradients work well for profile pictures, product shots and social media posts.
