It does the job, but the user interface feels clunky. For example:- There is no File → Open dialog. You need to go to a button somewhere.- You can crop, but it doesn't automatically help you crop by snapping to the first pixels when getting close to it. It's all manual in a tiny window that cannot be enlarged. - Even after painfully choosing your crop, you cannot store it as a preset. So you have to do this for every file.- There is also no File → Save dialog. I had to right-click a filename in the left panel of the UI, then click "Share" and that opened a file save dialog.

This app is a godsend for me, a student gone paperless with GoodNotes.I can now crop the pages to have just the right width so that my pages won’t wobble due to inconsistent width,and crop pages to the perfect length as well, to leave out any information I don’t need, which saves me a lot of time from scrolling through the needless margin.I saw the negative reviews and thought that’s weird... Maybe this app came a long way though the versions.I just came at the right time to scoop up the most refined result.It has options to crop all pages by the same selection at one time, or to crop single pages within a multi-page PDF file, and I have use for both.All in all, thank you for satisfying this niche but very much essential demand!

The app is very limited in its ability to crop. You are offered options to crop to the size of various device screens, or to specify a dimension, or to do any of a number of “unlimited” size cropping, but that does not work well if you do not know the dimensions of, let’s say, of a part of an article you want to preserve in crop. And if the article is very long, as in a web page that was saved as a PDF, you are unable to zoom in on the article to even see where you want it cropped. I am very disappointed.

In order to make it more practical please add several other options like crop odd pages only or even pages only also crop certain pages with certain numbers
