I was trying to implement a lossless image compression on a jpeg file to reduce it’s filesize. And I found jpegtran while searching the internet for solutions on lossless image compression. But after searching the internet for quite some time, I’m still a bit confused.
Is jpegtran part of PHP? or is it part of a third party application? And if so, what applications would I need to install, and how would I call jpegtran using PHP?
