By Readdle

PDF Expert 5 is a must-have app for anyone who reads, annotates or edits PDF documents on the iPad. It allows you to markup documents with highlights and handwriting, insert text and stamps, sign and even merge PDFs. Moreover, PDF Expert is the best choice for filling out PDF forms right on your iPad.

You can open various file formats such as iWork, MS Office, Power Point, text files, images, even music and video files, etc. Be these files from desktop computers, email attachments, documents on the Dropbox, SkyDrive, GoogleDocs and in other iPad applications you can store them in PDF Expert 5.

PDF Expert 5 provides the best support for filling out PDF forms. Text fields, check boxes, radio buttons and other form elements work as you expect and all the information you enter is saved within the form. Even complex interactive forms with Javascript work impressively well.

With PDF Expert 5 you can:

- Highlight Text -
Mark important things in books, journals or documents you want to review.

Other things PDF Expert lets you do:

+ Read PDFs with ease
PDF Expert has one of the best PDF viewers for the iPad. It opens large files, supports full text search, handles PDF links and outlines, opens password-protected documents and extracts text from PDFs.

+ Copy Files From Mac or PC via Wi-Fi and USB
Use iTunes file sharing to transfer files directly to your iPad via USB cable. As an alternative connect your iPad running PDF Expert via Wi-Fi and operate it like a wireless flash drive. No additional software is required.

+ Save Email Attachments
Open attachments directly from the Mail app. Also, you can open PDF files from any other application on the iPad via "Open In..." dialogue.

+ Edit Documents on a variety of storages
PDF Expert allows you to download and upload files from Dropbox, Microsoft SkyDrive, Google Drive and other services. If you use more than one cloud storage, PDF Expert will handle all of them.

+ Share Files With Your Friends
Email files directly from PDF Expert with all annotations preserved.

+ Protect Documents with Password and Encryption
Restrict access to PDF Expert with a password to protect your files from unauthorized reading. Enable iOS Data Protection to encrypt everything while iPad is not in use.

+ Text To Speech
Now you can listen to e-books or audio files on the road or when you don’t feel like reading. PDF Expert 5 intelligently processes PDF books and uses iOS7 text- to-speech API to read them aloud.

And one more thing:

• Review Mode •
The Review Mode allows you to markup PDF documents in a very special way. Just tap anywhere on the text where you need changes and correct it in the text editor. The text that you delete is marked as removed while everything you add is shown as new text in different colors.

All your modifications are standard PDF annotations that do not affect text in the PDF itself, which is very important.

NOTE 1: Please note that Dynamic XML PDF Forms made with Adobe LiveCycle should be converted to Static PDF Forms format before filling out in PDF Expert.
NOTE 2: We cannot reply you in comments. If you have any comments or issues, please contact us directly at

I thought I loved iAnnotate

I've been using iAnnotate for about a year now with no real problems and under the impression that it was the best portion for PDF annotation for the iPad. I was wrong. After using PDF expert for just a few days I've completely converted over and now use this app as my only annotation app. You have the same functionality that iAnnotate offers but in a more clear and intuitive layout. Plus you have arrow, line, box, and circle annotation options that work extremely well, something I always thought lacked in iAnnotate. I'm thrilled with this one.


This is the best PDF reader/annotator in the app store. It is able to perfectly show me all the annotations/notes I take on Preview in MacOSX, and lets me modify them on the iPad through syncing with dropbox. It also has one of the best file management systems...I really think the $10 price tag is completely justified and well worth it.

My only suggestion would be to PLEASE add continuous scrolling. That is the only thing this app is lacking.


Best app I've used to read and annotate PDFs

I have tried many apps designed to make me paperless. My goal was to find an app which allows me to write on a pdf file without printing it.

This one has a better, easier to use, more cleanly designed and more complete set of tools than others I've tried. It connects to all of my cloud accounts and to my desktop computer.

Very complete user manual.

I think my search is over.
