| Fixture findings | This test offered full-size export without login and a mask option; complex-scene coverage remains limited. | Local processing with full-size output; complex curly-hair edges look blocky and smoothed. |
| Original historical observation | Img2Go exports a full 2048×2048 transparent PNG (4.2 MB) without login, achieving 99.89% foreground recall and 0.80% background leak while uniquely offering free 'Return Mask' and 'Alpha Matting' controls in the browser. | Constrained by lightweight client-side WebGL/WASM model capacity, complex curly hair outer edges show softer semi-transparent halos (mad_band=0.1481, SAD(k)=65.96) compared to heavy cloud models, but foreground recall reaches 99.38% at full 2048×2048 resolution. |
| Suitable uses · historical assessment | Designers and developers needing free, no-login 2048×2048 unwatermarked transparent PNGs or direct binary mask exports (Return Mask) | Privacy-sensitive users who require 0-byte cloud upload (100% local browser execution) and unlimited no-login 2048×2048 full-resolution exports |
