What's the most annoying part of cropping a PDF?

Quick question for anyone who's cropped a PDF recently: what's the most annoying part of it for you?

For me it was always one of two things — either the "free" online tool wanted my email before letting me download anything, or the desktop app took 30 seconds just to open for a 10-second task.

That's basically why CropItFast exists: open, crop, done, no account. Curious if others have run into the same friction, or if there's a workflow (batch cropping, specific export formats, etc.) I'm not covering yet that would actually be useful.

Really — any suggestion is welcome, even if it's a small annoyance or a "wish this existed" feature. I'm actively building on this and would love to hear what would make it better for you.

Thx. :)
