| Measured fixture results | File reduction: 13.95% · Output size: 3560.8 KB | File reduction: 49.63% · Output size: 2084.2 KB |
| Fixture findings | On-device WASM lossless optimization reduced file size by ~14% with flawless PSNR and SSIM fidelity; requires a few seconds of local computation. | Reduced this fixture by about 50% with detail retained; avoid the sidebar ad resembling a download button. |
| Original historical observation | 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). | ResizePixel delivers remarkable quality in Auto (keep the quality) mode: shrinking our 4,137.9 KB PNG by 49.63% to 2,084.2 KB in 7.6s while maintaining a near-lossless 43.94 dB PSNR and 0.9994 SSIM (02_workspace.png). Users just need to ignore the green 'DOWNLOAD EXTENSION' ad on the left and click the real 'Go to Download / Download Image' button at the bottom right (03_download.png). |
| Suitable uses · historical assessment | Users and developers who require mathematical pixel fidelity (PSNR = 99.99 dB, SSIM = 1.0) while slimming down oversized PNG assets quickly without registration | Users who demand near-lossless visual quality (43.94 dB PSNR) or need to shrink an image to an exact KB ceiling for government/exam portals |
