73hi Background Remover is a free, fully in-browser AI tool that cuts the subject out of any photo and gives you a transparent PNG — with no watermark and no upload. Instead of sending your picture to a server, the neural network itself runs on your device through WebAssembly (ONNX Runtime Web). Your photo never leaves your machine. Pick from four open-source models for the quality you need: Fast (U2Netp, 4.4 MB) — products, logos, and anything with a clean outline Better (Silueta, 42 MB) — subjects with thin parts like arms, straps, bike wheels, branches Portrait (MODNet, 6.6 MB) — people and pets, keeping hair, fur and beard strands Ultra (BiRefNet-lite, 94 MB) — perfect edges on hair, fur, glass, motion blur and complex backgrounds Fine-tune the edge after the cut (shift, feather, de-fringe, clean up colour rim) without re-running the AI, preview on a checkerboard, then download as a transparent PNG or bake in white, black, or any custom colour. Supports JPG, PNG, WebP, GIF and BMP. Free, no sign-up, no watermark.
