PicClip is another app I, and AI, put together.
I created this because EasyCrop (a Mac app from YellowMug) is no longer available, nor will it work after the next update to MacOS because it is Intel based. YellowMug does not have a newer version.
Yes, there are a multitude of (paid) options to choose from that could do the job, and I already have 2 photo editing apps that could carry the load. But the ones I have require a bit of navigation to get to where I need. I do a bit of cropping, and often, I want something SIMPLE and quick. PicClip fits the bill.
I initially thought about putting it in the App Store, but after looking at all the options out there, I figured it would just get lost in the crowd. So I decided to put it on Github and move on.
In case anyone asks, the PNG aspect is limited to cropping, it does not include reducing file size. I was looking at pngquant, but I need to review the licensing or look into other alternatives.
