How to Put a Photo on a Pure White Background
Remove image backgrounds and swap background colors with Koutuxia. Powered by the BiRefNet model, export transparent PNGs or red, blue, or white solid backgrounds in seconds — free to use.
Pure white is the most forgiving backdrop there is — it prints cleanly, it never fights the subject, and it's what marketplaces and slide decks expect. You don't need a lightbox or a studio for it. Remove the original background with Koutuxia, then drop the cutout on #FFFFFF.
How to do it
Step 1 · Remove the original background
Drop your photo in and use Fine mode. AI cuts out the subject, the background goes transparent, with clean hair and fur edges.
Step 2 · Download transparent PNG
Download the cutout — your subject floats on transparency, ready for any background.
Step 3 · Add white & set the size
Add a pure white #FFFFFF background in any image tool and export at whatever size you need.
Getting white right
- ·Use pure #FFFFFF, not off-white — near-white reads as dirty next to true white
- ·Watch for a grey halo on light hair; Fine mode handles the edge better than Fast
- ·White on white: a subject in a white shirt needs a faint shadow or the edge disappears
- ·Export as PNG if anything will sit on top of it later, JPG if it's final
FAQ
Does it add the white background for me?
Koutuxia handles the hard part — cutting the subject out cleanly. Compositing onto white is one step in any image tool, and built-in recoloring is on our roadmap.
How white does it need to be?
Pure white #FFFFFF is the safe answer. Light grey or off-white looks like a mistake once it's next to real white.
Do glasses or fine hair affect the cutout?
Fine (BiRefNet) mode handles hair strands and glasses frames well. Evenly-lit shots with a simple original background give the cleanest edge.
