| Fixture findings | This test exported a full-size transparent image without login; inspect fine hair locally. | Local processing with full-size output; complex curly-hair edges look blocky and smoothed. |
| Original historical observation | Aiseesoft Free Background Remover is a rare true zero-gate full-resolution tool: it exports a native 2048×2048 unwatermarked RGBA PNG without signup, achieving 99.82% foreground recall and 0.313% background leak (mad_band = 0.1766). | 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 | Users seeking a 100% free, no-login, full 2048×2048 watermark-free transparent PNG cutout | Privacy-sensitive users who require 0-byte cloud upload (100% local browser execution) and unlimited no-login 2048×2048 full-resolution exports |
