Scoring version 2.3.1 · Test fixture anchor_compress_v1
Honesty & reputation · 93/100 · 30%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Pricing transparency | 35 / 35 | 100% free with no account registration, paywalls, or file-count caps; the landing page and workspace clearly disclose upfront that PNG inputs are converted to WebP for maximum compression (Format: PNG → WebP). Dropping our 4,137.9 KB (2048×2048) anchor PNG immediately enabled a free 276.0 KB download (01_landing.png, 02_workspace.png, 03_download.png). | Evidence A → |
| Interaction restraint | 29 / 30 | Zero registration prompts, ad overlays, or deceptive redirects; dropping an image immediately displays original size, compressed size, reduction percentage, and a direct download button. | Evidence A → |
| Background & reputation | 14.5 / 20 | Independent client-side browser image toolkit launched in 2026 with clear privacy documentation and contact channels, though without a disclosed corporate entity name. | Evidence B → |
| Engineering & privacy | 14.5 / 15 | Verified via browser network monitoring: image compression runs 100% locally via Canvas / WebP encoding with zero bytes uploaded to any remote server (upload_s_net = 0s). | Evidence A → |
Capability · 91.5/100 · 70%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Task quality | 59.5 / 65 | In default Balanced mode, compresses the 4,137.9 KB (2048×2048) PNG anchor to a 276.0 KB WebP (-93.33%, 14.99× ratio) while achieving PSNR = 37.75 dB and SSIM = 0.9977 (59.5/65) | Evidence A → |
| Deliverable specifications | 17 / 20 | Preserves 100% of the 2048×2048 pixel resolution with zero watermarks or login walls and supports multi-file ZIP export; 3 points deducted because PNG inputs are converted to WebP (explicitly disclosed as Format: PNG → WebP) rather than preserving a native PNG container (17.0/20) | Evidence A → |
| Processing speed | 15 / 15 | 100% client-side local browser encoding with 0.0s network upload or server wait, completing the 2048×2048 anchor in ~0.54s end-to-end (15.0/15) | Evidence A → |
