It er also a Crop mode switch. It only works in documents that have been OCRs, and unlike some other programs like GoodReader where you can adjust the delimitation margins yourself, in PDF Expert, the app automatically crops the empty margins. I don't like what you can't adjust how much or how little crop it is, but sometimes the automatic cropping works well, and when it does, it's easy to hide the margins on a document so you can make the text even bigger and easier to read.
To quickly scroll through a document, drag a very small gray rectangle to the side of the screen. Once you have taken it, it works, but the rectangle is so small that I often find it very difficult to grasp, especially when it is completely up or down. This is actually one of my biggest gripes with this app. It is easier to take it when using the exact tip of an Apple pencil, but I wish it worked better with a finger. Just making the rectangle bigger will probably be a simple solution. I prefer the way GoodReader handles by scrolling through a document – placing small preview thumbnails along the bottom of the screen so you can drag your finger left or right to scroll quickly.
Tap the magnifying glass icon to search for specific words in the document you are viewing. This is fast and works very well.
You can use bookmarks in a document to make it easy to go back to a page in the document that you had previously considered important.
If you press the Pages button on the toolbar, you can see thumbnails of each page. This is a great way to browse a document and look for a particular page. You can also select one or more pages and manipulate them in different ways, such as moving pages around, exporting certain pages, rotating specific pages, etc.
The other way to annotate is to tap the tools on the toolbar that appear when you press Note to select a specific tool, For example, a pen, a circle or a square, underlying, st-rich-through, a postage stamp, etc.
There is an undo button at the bottom of the toolbar. Press it once to undo the last action. Hold it down to undo or repeat multiple actions, a useful feature I haven't seen in other apps.
When you tap the pen tool on the toolbar, four pens appear on the toolbar. The two top pens are normal pens with a specific color and thickness that you can choose. Personally I find 1 pt a bit too narrow and 2 pt a bit too thick; I prefer GoodReader where you can also choose 1.5 pt. The two lower pens are pressure sensitive pens. Again you can choose color and thickness, and here you can choose more thicknesses as 1.5 pt. The pressure-sensitive pens make ink thicker when you press down and thinner when using less pressure. I'm sure this is fine for artistic drawings, but when I notice a card sent to me by the opponent, I find pressure sensitive pens to be unnecessary and even annoying. Fortunately, it is easy enough to ignore the two pens at the bottom, and it's nice to be able to tap one of the two top pens to quickly switch between two previously selected pens, such as a thicker red pen or a thinner blue pen. You can also customize the opacity of pens, but I always keep my set to 100%.
After you write a comment, you can tap it to change it, such as changing the colors of something you wrote, thickening the ink, changing the opacity, deleting the note, etc. You can also use a rectangular loading tool to select multiple annotations simultaneously, and change or delete them.
You can tap an icon at the top of the screen to see all your comments in a document, making it quick to jump to a specific location. If you used highlight or highlight, you see the actual words you used annotating, which is useful. If you handwrote something, you just see a pen icon to show you that you did it; There is no preview of what you wrote or something like.
In the main part of the screen to the right you will see a list of folders and files. end of a row to see a menu of options that move, rename, duplicate, zip, etc. If you hold down a file name for a second, drag and drop that file to another location.
Although these are the most useful parts of the app for me, there are many Other Features You can zip and extract files You can see file types other than PDF files, even if you cannot annotate other file types like Microsoft Word files. You can fill out PDF forms.
For additional $ 9.99 in app purchase allows you to enable the function of editing a document. Paid for this feature, I find that I never use it because I basically never need to change a word in a PDF d ocument. The feature appeals to you, you can purchase this option.
You can flatten PDF documents, but PDF Expert missing some of the more sophisticated security features found in GoodReader, such as the ability to remove all metadata using Secure Photocopy function.
PDF Expert also works on iPhone. Although most of my work is done on an iPad, it is sometimes nice to see or manipulate a file on my iPhone.
PDF Expert is an amazing app. It is no exaggeration to say that I use this app every single day I work. Having all the files I need with me at all times is useful, the annotation features are great, and PDF Expert has many options for manipulating files. There are a few features in GoodReader that I would like to see added to PDF Expert, and I still find myself using GoodReader for some tasks. But in general, PDF Expert is my favorite to work with PDF documents on an iPad. This app helps make me a better lawyer.
