AI background remover / cutout
Background removal separates the subject from its background and erases the background. image cat runs an AI model (MODNet) locally in your browser to remove the background in one click and export a transparent PNG, accelerated by WebGPU with an automatic CPU fallback. The model downloads once from a public CDN and is cached; inference runs entirely in your browser — images are never uploaded.
Works best on people/subjects. Fine edges (hair, translucency) may have minor artifacts.

Frequently asked questions
It runs entirely in your browser; photos are never uploaded. The AI model downloads once from a public CDN into your browser cache, then inference runs offline.
The first use downloads a ~40MB AI model — usually seconds to tens of seconds depending on your connection. It's cached afterwards, so later runs are near-instant.
Great for clear subjects like portraits and products. Very fine hair, translucent objects and edges close to the background color may show minor artifacts — the trade-off of a lightweight local model in exchange for privacy and being free.
After removal, everything outside the subject is transparent, and only PNG (or WebP) supports an alpha channel. For a solid background, use the ID Photo or White Background tool.
