| Original historical observation | CompressNow is a fast, 100% client-side compressor: your image never leaves your browser, and in 0.9s it shrinks our 4.24 MB benchmark PNG to 579.8 KB (-85.99%, 7.14×) at 42.34 dB PSNR (02_workspace.png). Note that it only outputs JPG or WebP (disclosed upfront), so users with transparent PNGs should select the WebP toggle. | IMG2GO offers a comprehensive 7-mode compression settings panel (02_workspace.png). Under the default 'Recommended compression' preset, it aggressively shrinks our 4,137.9 KB PNG by 78.49% to 890.1 KB (03_download.png) at 31.68 dB PSNR; quality-focused users can select 'Less compression' or 'Lossless compression' before clicking Compress Now. |
| Suitable uses · historical assessment | Users who want to rapidly shrink bulky PNG screenshots or photos locally in-browser into high-quality JPG or WebP (-86% size) without uploading files to any server | Users who want granular preset control (Lossless / Less / Recommended / Extreme / Target KB) and GDPR-compliant instant task deletion |
