You can open and view various file formats such as iWork, MS Office, and PowerPoint and text files, images, music and video files, etc. You can easily import these files from desktop computers, email attachments, documents in Dropbox, OneDrive, Google Drive and “Open in" from other applications by hitting the prominent “+” button.

PDF Expert 6: Read, annotate & edit PDF documents Reviews


This is it  tjcermd  5 star

Found out about this at a medical conference and immediately downloaded it. Within minutes I was using this app. It is easy to use, intuitive and makes adding notes sooooo easy.


Used to be nice, now fairly pointless  Meehanite  1 star

The last update removed the ability to annotate files, so I'm not really sure why this app still exists? Money-grab before iOS adds universal PDF annotations, I suppose? Still decent for reading/organizing, but that's all.


Fantastic annotations  Searching4Bliss  5 star

Highlighting, underlines, boxes, stylus writing, typing, stamps...you name it, it does it.


DO NOT Update! Pay again!!  RickDS_iPad  1 star

This company quickly released 5th update of version 6 to hide hundreds of 1-Star bad reviews from their initial release of version 6. Good try! That makes us the previous loyal customer base despise you even more. Disappointing! My original review on 5-15-2017 **Be Careful! Do NOT update to this version 6!! ** Many of us already paid the Pro version in "5" for the edit feature!!! Why do we have to pay again in version "6"? That's greedy! This company is becoming unethical and unprofessional!! It's very disappointing. Please STOP your rhetorics to me and others about it's reasonable to charge extra $10 for the same edit feature. It's NOT! Because, edit feature had been there in version 5. I was able to edit in previous version, now I cannot!!?? You can charge for new feature that's not in version 5. But editing is NOT a new feature! Please return the edit feature back to us, we paid for this feature!!

Double page mode  重华521  3 star

I bought an 12.9 inch iPad Pro to read some book in PDF format.It would be very convenient if the software could support double page mode as GoodReader.


Outstanding  nmejd  5 star

I use my iPad for reading and annotating documents. Have tried most of the other apps for storing and annotating documents. This remains my favorite along Documents. I wish I could get a second copy of these apps because of the number of documents I have stored in them. I'm sent this a second time because it's still true. And now I'm sending a third time.

This app is just getting better. Simply the best


Good app but recent version is not working on my phone  jinnitu83  3 star

I purchased this app and I absolutely love it! But, ever since the new update my phone hasn't been able to "update" it. So to try to resolve the issue I uninstalled it from my phone. Bad idea! Now I cannot download it back to my phone at all! I'm not happy since I use this for my business and paid for the full version. I hope they they ca fix this as soon as possible. I am very frustrated.


Used to be my preferred PDF app  Cinderella427  2 star

Since this new update it gets buggy if I use multiple languages in my annotations. It also doesn't work well now with split screen viewing. It glitches far to often for me. If it were more stable I would recommend it to others.


Disrespects users  BetterEnzyme  1 star

Unfortunately, PDF Expert hassles users to rate the app.


Update failed to install  NC_Rick  1 star

When a new update will not work with older iPhones ( those not the newest) they should tell people. I have a iPhone 6 and the update will not install.

Xxx FuQ

Nothing more than reader  Xxx FuQ  1 star

I bought the app for business purposes with the understanding that after spending $10 on the app, I could read AND edit PDF documents. But in order to edit, you have to spend an additional $10 to "upgrade". Complete and total waste of money.

Me slowly

Best PDF reader  Me slowly  5 star

It's completely suitable for every need I have. Writing, highlighting and even stamping are helpful features but the main characteristic is smooth working even on older devices.

Gravely Dissappointed

iOS, Mac OS and WIN 10  Gravely Dissappointed  5 star

Can finally edit PDFs in just a short amount of time without procrastination, looming dread or pulling an all-nighter....unlike the horrors of days gone by. Could spend hours searching for ways to convert a PDF into a usable format for editing and then back to PDF for sharing. Especially useful when encountering the need to complete forms that are filed by their agency/owner as PDF. My handwriting is impossible. May as well hand the pen over to Rover. So for me, typewritten forms are a requirement in both my personal and business lives. Thank you Readdle. You Rock!


Doesn't restore purchases  Starshyne13  1 star

This version has some great new features. However, it will not restore previous purchases. You have to pay to get some of the features included in the initial purchase, like PDF editing.


Great app, almost like paper but better.  Zeepaco  5 star

I use for documents, and scheduling that needs to be updated. Love it!
