Full text search in a online PDF flip book publication

Thursday 27th March 2014


Today’s blog will explore the full text search function within the FlexPaper classic viewer and the Flexpape Zine viewer. Being able to do a text search in a published document is a basic functionality that is a must in any page flip publication you find online no matter what software you use.

There are two problems that can destroy your user experience, the first is if the uploaded document consists of scanned images making it impossible to do any text search at all. The other one is when you are searching through a large document, slowing the search and browser down because it has to download the whole document before a full text search can be done. 

 Both FlexPaper viewers let your readers do a full text search without needing to download the whole document. They even handle OCR scanned documents. Your search result will be clearly displayed in the document in a search abstract in the search index to the left of the browser as seen in the top image.

Online PDF viewer with full touch support and crisp output

Wednesday 19th March 2014


Today, customers expect to be able to view your publications on mobile devices and this means that the software you use to publish your PDF documents will need to be able to detect what device your readers use. It also means that it needs to have touch gesture touch support.

FlexPaper Zine viewer includes a adaptive user interface that not only detects what type of device your readers are using, it also switches to full gesture support and enables pinch zoom. Another beautiful feature you will get is the crisp result when you zoom in really close into the publication. Forget pixilation and get the same sharp out put on retina displays.   

Privacy and protection of your online PDF publication

Tuesday 11th March 2014

Internet privacy has been heavily debated during the recent year. It has mostly been focused on the privacy breaches for consumers but it could easily be about company’s privacy and protection, especially when you use a cloud based service provider to store and upload your documents and data. We believe that your privacy is important and we believe that your content is your business.

 Two things to think about when you use a cloud based service or software.

  1. Does your service provider use cookies to collect data from you and your customers?
  2. If you use a third party service to publish your documents, who’s servers is the software communicating with?

FlexPaper does not use cookies so you can be sure that we don’t collect any data. Our software only communicates with your servers leaving your privacy intact and 100% in your control.

Signing & obfuscation
We understand the importance of privacy and the need to protect your content. FlexPaper Desktop Publisher features a sign and time frame feature that gives an extra layer of protection to your documents. 

Please note – Because we do not store any of your data you need to save all your passwords or re-publish the document if you loose any password.     

Offline publishing
If online publishing is not an option for you, we also offer offline alternatives to publish your documents. You can publish to DVD, CD or USB.

How to share a PDF on social networks like Twitter, Facebook, Tumblr and LinkedIn

Wednesday 5th March 2014

FlexPaper Zine now offers the possibility for you or your readers to share your publications to a range of social networks. Publications can be shared on Twitter, Facebook, Tumblr, LinkedIn or embedded on any site.


The quickest and easiest way to take advantaged of this new feature is to publish your PDF document via our desktop publisher. We have added the social network function to the toolbar.


When your readers want to share your content, they press the social sharing button in the top menu bar and a pop-up window appears.

There are a number of options for you to choose from. You can use the publication url directly, select a specific landing page or you can add a title and select any of the listed social networks. The pop-up window menu also allows you to embed the publication into any website.

This feature is available from version 2.2.3 that was released February 16.

How to make Google index PDF files

Sunday 23rd February 2014

Do you struggle to get Google to index your PDF publications with organic search? Then we have some great news for you. In our latest version of FlexPaper Desktop Publisher we have added a new option that will help your publication get a higher ranking, be easier to track in analytics and be indexed better.

Traditionally, when Google indexes your PDF documents, it will index your files as a whole and there is no way of collecting statistics on why and what people where looking for in a document. This is because the way the publication is generated.

With our new feature, FlexPaper Desktop Publisher will create a text only version of your PDF. This means that when Google, or any other search engine indexes your FlexPaper documentation, it does so on page by page basis which increases your exposure and hits. It will also allow you to collect data on how and why people land on your pages. 


You can access this feature under the publish button in the desktop publisher. Expand the advance settings menu.


Tick the “improve conditions for search engines to index your publication” box. Please note that you need to have PHP support on your server.

This option is available from version 2.2.3 version of FlexPaper Desktop Publisher. Give it a try, download our desktop publisher here

A case study in creating PDF flip books: chasing the cursor or dragging the contents

Thursday 6th February 2014

There are a range of settings that can be done with FlexPaper in styles and behavior settings. The output format can be HTML5, HTML4 or Flash, colors and backgrounds can be set, icons can be changed and the viewer can start in different modes. This week we are having a look at the way your users can navigate inside your PDF documents when using page turn animations like in FlexPaper Zine. This tutorial uses FlexPaper Desktop Publisher which can be downloaded for Mac OS X and Windows from here:


Start Desktop Publisher and locate the viewer behavior settings
Desktop Publisher has its settings divided into different sections for each of the type of settings that can be made. The setting we are after in this little tutorial is the “Zoom Dragging” setting which can be seen after scrolling down to the very bottom in the “Viewer Behaviour Settings” section.

This setting is turned on per default. When turned on, the viewer will allow the user to drag the document using its mouse when zoomed into a document. You can see this by clicking on the document so that the viewer zooms into the document and then use your mouse to drag it around. Another example of a PDF published with flip book effects where you can zoom in and use your mouse to navigate the contents can be seen here:


This example renders in flash per default but you can easily switch over to use html5 if you prefer that.

If you on the other hand prefer to let your users navigate your publications by tracking their mouse movements then turning the “Zoom Dragging” feature off will allow you to do this. Turn the feature off and zoom into the PDF inside desktop publisher and you will see how the publication now tracks the mouse movements as you move your cursor. An example of this can be seen in the following publication:



What about mobile devices?
In mobile devices the publication will always allow the user to drag around the content, since there is no mouse cursor to track. In computers which have both (like in PC’s using Windows 8), both interactions can be combined if you set the “Zoom Dragging” feature to off.

How to track page views in PDF documents for page flip publications using Google Analytics

Tuesday 28th January 2014

PDF files typically act as a external component inside your web page and interacting with them from your web site isn’t typically possible, therefore tracking how your visitors view your PDF files can be tricky. This tutorial shows how to track your visitors reading habits for your PDF documents when using FlexPaper.

Publishing documents in FlexPaper can be done in multiple ways. The easiest way to convert a PDF document to a web publication is to use our desktop publisher. Desktop Publisher features the ability to add your Google Analytics tracking code without any programming knowledge. It is available in both Mac OS X and Windows.

The first step is to fill out the field with your Google Analytics tracking code. It typically looks like something this: UA-10199999-1. The screen shot above shows where to enter your tracking code inside desktop publisher. Now all you have to do is to publish your publication (using the “publish & view button), upload the contents to your web server and wait for the statistics to roll in. 

After logging in to Google Analytics, the statistics for your documents can be found under "Behaviour” and then “Events”. You can see the path to the analytics pointed out in the screenshot below and marked with [1] and [2]


You can choose to view the analytics by Category, Action or Label. We have chosen to view them by label as this also shows how many times each page in the PDF document has been viewed. You can see the page views in the screen shot above marked with [3].

We hope this tutorial helped you in understanding how to start tracking your visitors and their behavior inside your PDF documents using Google Analytics!
