I’ve been using CodeKit for all of my LESS and JS compiling/minifying needs while doing my frontend development lately. I love it, and it was well worth the $28. But now I am looking for a Windows alternative. Don’t worry, I’m not switching back to Windows. Just something I could recommend to my fellow developers that use Windows. I found Prepros which looks great and is highly recommended, but it’s not free or open source. I personally don’t care, but I know people who wouldn’t use it because of that….. any others I haven’t found yet?
A friend of mine pointed me towards Koala which is cross-platform and open-source. After looking into it, I can say it is pretty nice. Not quite as many features as CodeKit, but still a great free and open-source app. I’ve already recommended it to about 6 other developers and they seem to like it, too.
I don’t know that I really believe in “lossless” JPG compression. I read an article about a month ago that said it’s hogwash. Plus, I can usually see a difference in quality when I use these tools.
PNG does compress quite nicely. Those photos lose A LOT of extra weight… like 80%. *I could be wrong but my understanding is that PNG files have a lot of embedded meta data that you don’t need. Therefore, by cutting all that out, they get quite small.
Again, I don’t think Koala has that feature but you can get a command line utility like ImageMagick and batch compress/resize/rotate all your photos at once.
I personally like Prepros myself, there is a free version and a Pro version. While other solutions might work, no other has Autoprefixer, which is beyond amazing to have work in tandem with the preprocessor.
