Change Photo Background — Solid, Gradient or Image

It runs an AI segmentation model in your browser to cut out the subject, then composites the cutout on top of the background you pick. Solid color, gradient, your own uploaded image, or a studio preset — the math is the same: alpha mask + Canvas drawImage.

No. The AI cutout and the compositing both happen entirely in your browser. The original photo, the chosen background, and the final image never leave your device. After the model is cached on first run, the tool works fully offline.

Solid color is great for branded social posts and thumbnails. Studio presets (white, off-white, gray, dark gray) match the seamless backdrops used in product photography and corporate headshots — pick those for LinkedIn DPs, e-commerce listings, or marketplace photos. Gradients work well for hero images and lifestyle posts.

That's edge contamination — pixels around the subject contained some of the original background color, and they show up against the new one. It's most visible when the new background contrasts strongly with the old. Try a background closer to the original color, or pick a studio preset (which is forgiving), to minimize the halo.

The composite is exported as PNG. PNG preserves edge quality and avoids the JPG compression artifacts that often show up around hair and fine edges. If you need a smaller file, run the PNG through our Image Compressor afterwards.

Yes — pick the ‘Upload image’ tab and drop any JPG, PNG, or WebP. The background image is automatically scaled to cover the canvas (no stretching or letterboxing), keeping the subject in the foreground at full resolution.

Hair and glasses generally come out clean — the segmentation model handles soft edges with proper alpha gradients, not hard binary masks. Cast shadows on the original ground plane are usually removed along with the background; if you need a realistic drop shadow on the new background, add it in your editor afterwards.
