Sites like github often "optimize" images to lower bandwidth costs. Basically any platform you share images on that is at scale will probably re-compress images. For PNG they often reencode the image in a lossy way.
- IAmEveryone 7y agoGitHub doesn’t “optimize” your images, just as it doesn’t format your code. People would storm the barricades if Github changed their files.
- SahAssar 7y agoThey do change files that are embedded in readmes, just like most web platforms do. The original file is unchanged, but the version embedded in the readme preview on github.com is changed.
