Background Eraser — Free, Fast & Private
A background eraser does what the name says: erases the area around your subject and replaces it with transparency. MiniPx's eraser is AI-driven (BiRefNet model) and runs in your browser — no upload, no signup, no quota.
Unlike paintbrush-style erasers in Photoshop or similar editors, this one detects the subject automatically. Drop a photo, wait 1-5 seconds, get the transparent cutout. For images where automatic detection misses (very low-contrast subjects), the cloud-based remove.bg-style services may produce slightly different output — but for portraits, products, and most everyday photos, on-device wins on privacy and cost.
The interactive eraser lives at /background-remover/. If you want to keep the eraser output AND compose it onto a different color, the Pro tier exposes a color picker for white / black / cream / custom backgrounds.
