| 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). | 35 / 35 100% completely free with no subscriptions, paywalls, or resolution reductions. Uploading our 4.24 MB (2048×2048) anchor PNG immediately yields a lossless compressed download (01_landing.png, 02_workspace.png, 03_download.png). |
| 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. | 28 / 30 Zero mandatory registration, no gating popups, and no artificial countdowns.

| 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) | 57 / 65 Lossless OxiPNG compression reduces 4,137.9 KB to 3,560.8 KB (-13.95%, 1.16× ratio) while preserving flawless 100% pixel fidelity (PSNR = 99.99 dB, SSIM = 1.0) (57.0/65) |
| 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) | 20 / 20 Preserves native 2048×2048 dimensions and full alpha transparency with zero watermarks (20.0/20) |
| 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) | 12 / 15 Client-side WebAssembly (OxiPNG) execution takes ~4.0s with zero network upload latency (12.0/15) |
