About JuanJuan Tools

What we do

JuanJuan Tools is a free, privacy-friendly online image toolkit. We believe high-quality image editing shouldn't require an expensive subscription or a steep learning curve.

• Background remover — automatic background removal with hair-level edges, smart refine, sticker borders, and natural shadows
• AI upscaling — 2x super-resolution with detail sharpening

How we build it

• Privacy first — AI models run locally in your browser by default; images never leave your device
• Free to use — guests get free uses every day, no registration required
• Open and transparent — core models (U²-Net, MobileSAM, Real-ESRGAN) are open-source projects
