in this page i’ve tested an already compressed image against the original png tested here
Source Image: {{originalImage.filename}}
compress {{originalImage.compression}} palette {{originalImage.channels}} folder_zip {{originalImage.filesize}}
aspect_ratio {{originalImage.width}} x {{originalImage.height}}
warning SSIM {{originalImage.ssim.all}} – PSNR {{originalImage.psnr.all}}
Reference Image: {{ referenceImage.filename }}
compress {{referenceImage.compression}} palette {{referenceImage.channels}} folder_zip {{referenceImage.filesize}}
aspect_ratio {{referenceImage.width}} x {{referenceImage.height}}
VS
| Target SSIM | Similarity | Name | Size | Time to encode |
|---|---|---|---|---|
| {{image.similarity}} | {{ extendedFormatName(image) }} | {{ getFileSize(image.sizebyte) }} | {{image.encodetime}} |
sort={{currentSort}}, dir={{currentSortDir}}, page={{currentPage}}
{{currentCompare.left}} vs {{currentCompare.right}}
