Reducing .PNG file size

Postby chad3006 » Tue Jan 28, 2014 9:46 pm

On some of the cars I've made I've used a web app called TinyPNG (https://tinypng.com). It reduces the filesize while preserving the alpha channel (transparency). But I also discovered a command line version called pngquant (http://pngquant.org) that apparently uses the same algorithm that TinyPNG uses. There is some loss in image quality, but I've personally not found it very noticable. Anyway, I though it might be a handy tool for SD.

We might also want to ensure that we're not packing extrenuous files:


There also the question whether we can save space by symlinking identical files in the installers.

OK, I wasn't aware of Optipng.
