About the background remover
Background removal is one of the highest-volume image-editing tasks on the web, and renza's remover does it free, without signups or watermarks. It runs BiRefNet, a state-of-the-art segmentation model that handles people, products, pets and fine hair with a true alpha channel, and the result comes back within seconds. If the model is busy, a compact in-browser model takes over so you always get a result.

Tips for best results
Things that meaningfully improve the output.
People and pets work best
The free in-browser model is a portrait matting specialist. Headshots, full-body photos and pet portraits give the cleanest cutouts.
Good lighting separates subject from background
Photos where the subject is clearly lit and contrasts with the background convert cleanest. Backlit or low-contrast photos are harder.
Products, glass and fine hair
BiRefNet handles complex product silhouettes, jewelry and hair against busy backgrounds. Good light and contrast still help.
Want a new background instead?
If you want to replace the background rather than just remove it, use /tools/background-changer, one step, and the new scene lighting matches the subject.
Need more than background remover?
renza's AI tools remove backgrounds, erase objects, restore old photos and upscale to print quality. Free credits at signup, no credit card.

Is the output a transparent PNG?
Yes, a real one. The free remover produces a PNG with a true alpha channel, ready to layer over any design, slide or product page.
Is it really free and unlimited?
Yes: no watermark and no signup. There is a generous daily cap per visitor to keep bots away.
What is the difference between free and Pro?
There is no Pro tier: everyone gets the BiRefNet cut-out. If you want a new background instead of none, use the background changer, which re-renders the scene with your subject in place and matches the lighting. A few credits per photo, packs from $4.99.
Commercial use?
Yes, output is fully yours to use commercially.
