It's all free in macos preview app and it just works.
No one want to spend 30 minutes looking for website that allow to compress pdf because it's a slightly too big to be sent through email...
I do think Sumatra PDF is good for Windows software, it's not bloated and it's fast.
certainly, but 99% computer user never ever opened the terminal. And even then, good luck rotating page 4 of by 270° using terminal, then inverting it with page 5 and filling the form.
Things that would take 5 seconds on preview.
I appreciate your enthusiasm but man you're over complicating stuff. Beside LLM hallucinations, you would have to type to the computer everything you want to do. I can rotate page with one click, move them to another part is doe with a single mouse drag.
