In order to calculate this resolution you just use the same formula you would use for the area of any rectangle multiply the length by the height. The first kind of resolution refers to the pixel count which is the number of pixels that form your photo. Here you see the Lossless compressed ~15.000 bytes icon from convert to the left - And the compressed 1.The amount of these pixels and the way they are distributed are the two factors that you need to consider to understand resolution. I’m betting that the size of your final ico.ico from your screenshot is ~15.000 bytes (even making the initial compression redundant), and that’s what convert gives me, no matter which -compress type I’m using.Īnd not only that - it’s visually compromised as its transparency seems to be created against black, you can tell that by looking it the edges of the graphic in the icon.
But the important and interesting part is the. So minor bytes aside - we’re totally agreeing to the same thing here, with only a slight difference in tooling between windows and OS X. Image%20%20at%206.39.30%20PM.png 1270×857Īs you see, they came out at 726 bytes I got this result from using ImageAlpha for lossy but still not visible compression of transparent PNGs in conjunction with ImageOptim for lossless compression of the PNGs (you can verify this through the sources in the.
Your comparison of the importance of compressed assets for a potential inclusion on the website, to the importance of DTP in my zip on the actually pull request, just seems ridiculous to me.īut since I apparently don’t know much about compression in your opinion, I’m looking forward to your better and improved contribution at the Pull Request plus posting the solution to bundeling these three uncompressed PNGs into a favicon.ico without compromising visual quality while reaching a smaller filesize than the 1.629 bytes my solution achieves:įor an image delivery service I’d pick which (besides their Artificial Intelligent entropy crop detection) also supports client hints for stupid simple responsive images and correct delivery formats. This will not only visually ruin your favicon.ico completely, but also (even with pre-compressed sources) give it a weight of 15.086 bytes from the 1.629 bytes achieved by my suggested method. Since we’re talking about PLEASE READ: favicon.ico as my headline might give away, then you’d at least have to: # Install imagemagick on a mac( brew install imagemagickĬonvert favicon-16x16.png favicon-32x32.png favicon-48x48.png favicon.ico Thanks, for trolling me once again here - I’ve been running a SSIM JPEG compressor in production for the past five years, sir
