| Measured fixture results | File reduction: 57.73% · Output size: 1749 KB | File reduction: 13.95% · Output size: 3560.8 KB |
| Fixture findings | Kept PNG format while reducing this fixture by about 58%; check free file-size and quantity limits. | On-device WASM lossless optimization reduced file size by ~14% with flawless PSNR and SSIM fidelity; requires a few seconds of local computation. |
| Original historical observation | TinyPNG remains the gold standard for smart PNG quantization: without changing format or pixel dimensions (2048×2048), it cuts our 4.24 MB anchor PNG by 57.73% (1,749.0 KB) while achieving the highest fidelity in the category at PSNR=40.09 dB and SSIM=0.9987 (02_workspace.png, 03_download.png). | Ezgif provides a genuine lossless PNG compressor powered by OxiPNG: retaining full 2048×2048 dimensions and RGBA transparency, it cuts our 4.24 MB test asset by 13.95% (3,560.8 KB) at absolute fidelity with PSNR = 99.99 dB and SSIM = 1.0 (02_workspace.png, 03_download.png). |
| Suitable uses · historical assessment | Frontend developers, UI designers, and content editors who need to keep native PNG format (and alpha support) while cutting file weight by ~60% with virtually zero visual loss (PSNR > 40 dB) | Users and developers who require mathematical pixel fidelity (PSNR = 99.99 dB, SSIM = 1.0) while slimming down oversized PNG assets quickly without registration |
