Remove a photo background online.
Choose a people-focused photo, including a single person or small group. SizeFix keeps the subjects solid, removes the surrounding background, and lets you review the transparent PNG before saving.
Create a clean transparent people cut-out
SizeFix uses an on-device people-aware segmentation model that separates hair, skin, clothing and other person regions from the background. Those person classes are combined into a solid foreground before the edge is smoothed, avoiding the ghost-like transparency that can appear when raw confidence values are used directly.
The tool also checks the final alpha mask before showing a success state. If too much of the subject remains translucent or the foreground/background separation is implausible, SizeFix rejects the result rather than presenting it as finished. Start with Protect people for group photos, hair and loose clothing; use a cleaner edge only when extra background remains around the subject.
Background remover FAQs
Why can the first use take longer?
The people-segmentation runtime and model are downloaded on first use and can then be reused from browser cache.
Can it remove the background around several people?
Yes. The primary model combines all detected person categories, so a small group can be kept together instead of forcing the tool to retain only one person.
Can I save the result on a phone?
On supported phones, Save / Share transparent PNG opens the device share sheet. Otherwise the PNG uses the browser Downloads location.
Is this a universal product-photo remover?
No. This version is optimized for people-focused photos. Product and arbitrary-object cut-outs need a different segmentation model.
