Best available

I’ve been using this great tool with the weird name for years, on a site that has tens of thousands of user upload images. Works great. It’s fast, and just to make sure it’s the best available yet, I installed Imagify and gave that a try. Had a good compression algorithm, but rewrote too much backend stuff (media library pages, etc). Was incredibly slow, and it borked on 450 images of only 700 compressed – it took over 24 hours for that. Wrote 500 server errors to my Media library on every one?. It got removed and back to EWWW. It’s basic, it’s simple and it works. It’s been more of an AHHH. ??
