| Measured fixture results | File reduction: 85.99% · Output size: 579.8 KB | File reduction: 97.71% · Output size: 94.9 KB |
| Fixture findings | Local compression reduced this fixture by about 86%; export changes to JPG or WebP, not PNG. | Sample testing confirms: under default settings it heavily compresses file size by 97.7% to 94.9 KB with PSNR of 31.14 dB and SSIM of 0.9893, though deliverable size drops to 1024x1024 without alpha channel, earning an 80.3 overall score. |
| 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. | Bulk Resize Photos uses client-side Canvas processing; default settings heavily compress the 4.14 MB image by 97.7% to 94.9 KB, converting to JPEG and scaling to 50% in 140ms. |
| 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 needing ultra-fast, drastic image file size reduction where transparency retention is not required |
