In the past, I have not shied away from expressing my love for the PDF format PDF - The World's Digital Document [INFOGRAPHIC] PDF - The World's Digital Document [INFOGRAPHIC] I absolutely love PDF files as they are very practical. They're easy to read, you can encrypt them, sign them, split, rotate and watermark them, merge them, and navigating a PDF is effortless. In fact,... Read More . There isn’t a more robust way of sharing documents – send to anyone, open anywhere with a huge range of software. Unfortunately, this introduces difficulty when it comes to editing them.

For example, if I need to sign a PDF document, how do I do it without ripping out the little hair I have left on my head? Ideally I’d like to do this on my iPad, and while Dropbox doesn’t do a bad job of opening and presenting them on a tablet, I’ve been looking for something a little more… robust?

So when I was introduced to PDF Expert 5 by Denys Zhadanov, I was blown away at how easy the app is to use. Granted, it’s not cheap ($9.99), but if you are the kind of person who regularly views and would like to edit PDF files on an iPad, then this is most definitely an app for you.

Connecting The Cloud Storage Services

When you open PDF Expert up for the first time the first thing to do is connect your cloud services of choice, preferably where you store all of your PDF files. Most major sharing services are there (Dropbox, Google Drive, and Skydrive) and a few others which are just as good (SugarSync and Box). It is also possible to connect directly to FTP, SFTP and locally to a Windows SMB share too.

Tap on the ones you want, enter your credentials, and authorize PDF Expert 5 to access your files. You can revoke this access at any time by signing into the relevant cloud service and deleting the permission from the relevant page. When you have successfully connected an account, it will show up in the left-hand sidebar under Accounts. Tapping on one will then display the contents of that account.


Open PDF Expert Via Email

Another way to open a PDF file with PDF Expert 5 is directly from your email inbox.  Just tap on the PDF attachment and select PDF Expert 5 as the app to open it.

Then the file will open in the app appear in the main page as a thumbnail.

Tap on the document you want opened and all of the pages will appear as thumbnails on the screen. Tap the page you want to read and it will appear full-size on the screen.


Let’s start look at the feature I am most pumped about – signing documents. Right now, I am going through a huge period of reorganization in my life, and some long term decisions have required the signing of legal documents. Since we live in the 21st century, those documents have arrived via email, in the form of a PDF. And the email is always says the same – sign the relevant pages and send them back to us.

Then I look at my printer/scanner, suffocated under the huge pile of books and paper, and I suddenly feel deflated. The thought of digging the machine out, printing the page out, signing it, scanning it, converting back to PDF, emailing… there has to be an easier way, right?  Yes there is. PDF Expert makes it a lot easier.

Once you have the page you need to sign open, look on the left-hand side and you will see your editing tools. Cast your eye to the bottom of that bar and you will see a pen icon. Tap on that and it will bring up a blank screen for you to write your signature.

I used my finger to make my signature, but if you have a stylus pen, then all the better. Keep in mind that this signature will be shrunk down to a very small size. So although it looks a bit ugly and clunky at this resolution, once it gets shrunk down, it actually looks quite good as you will see below.

Sign the screen, tap Save, and then when you are taken back to the document, tap and hold where you want the signature to go.

You can drag the blue lines to position and scale the signature where you want it to go. Play around with it until you get it exactly the way you want it. If you totally mess it up, there is an undo button at the bottom of the left-hand toolbar, or shake-to-undo also works.


Sometimes handwriting is not good enough and it will become necessary to type in your PDF documents. Using the example above, I also need to insert the date. Rather than make a mess with my bad handwriting, it’s easier just to type it in.

In the left-hand toolbar, choose the T symbol (for text), tap where you want the text to go, and start typing. You can also choose the colour of the text. For some reason, red seems to be the default, so choose black from the selection. It goes better with the signature, don’t you think?

Stamps & More

If you are the boss of a company who gets sent lots of PDF documents to review, maybe you need some form of a stamp to say it has been read and approved?  That’s where the variety of stamps come in. As before, choose your stamp, then use the blue lines and blue circles to reposition and resize the stamp.

Choosing the highlighter will enable you to run your finger or stylus across words to be highlighted.

Maybe underlining is your gig?  Change colours, and run your finger across the relevant words to see them underlined.

If you are working your way through a list, striking out the ones that have been done is a huge help. As with underlining, choose your ink colour, then run your finger through the relevant words to see them struck out.

While reviewing a document, you may have a stray thought in your head that you don’t want to lose. That’s where the notes function becomes useful. A yellow note will appear on the screen where you can type whatever you want.

You can see many of these features in action thanks to the video embedded below.
