It is amazing just how much information we have today stored in PDF format. According to the PDF association, approximately 2.5 trillion PDFs are created every year, making up 6 percent of the web. However, as a web developer, PDFs on a website can present a variety of challenge:
- Viewing experiences vary greatly across different users and devices because they depend on a PDF viewer. Whether it is embedded in web browsers or free online libraries, some viewers are better than others. Adobe Acrobat Reader is generally the universal standard for viewing PDFs properly.
- It becomes difficult for me to be able to incorporate PDFs into the rest of my website. Most often PDFs would prompt users to download PDFs on their devices.
- Converting PDFs to HTML is difficult and unreliable. If I want to present content inside a webpage that is in PDF format, often I might flatten to PDF to make it easier to embed.
- I have no visibility into how my visitor is viewing those PDFs. This means I have no idea if someone is reading certain pages, how long they spend on those pages, etc.
Fortunately, Adobe has released Adobe Document Cloud View SDK (Adobe DC View SDK), an easy way for you to incorporate a PDF directly into your website with just an easy snippet of code. It is entirely free to use and renders client-side within your web app. You don’t have to learn a sophisticated PDF library, and it is super easy to do. No data is rendered on Adobe servers. In fact, you can even learn how to play with it here.
NOTHING! That’s the greatest thing about this. You don’t need anything other than a webpage to use Adobe DC View SDK.
Using Demo Site to try out the Adobe DC View SDK
The easiest way to get acquainted with the Adobe DC View SDK is to actually try it out on the Demo Site. It’s an easy resource to get started because it allows you to:
- See in real-time the different embed modes available for your PDFs.
- Customize which features you want as part of the viewer such as annotation tools, download PDF, Print PDF, page controls, etc.
- Generates code for you to paste right into your website.
Getting Your Client ID
If you want to try the Adobe DC View SDK in your own code, it works without a Client ID when you are using it locally. However, if you want to actually incorporate it into your website, you will need to get Client ID. Get your Client ID here.
Here are a couple of important tips:
- To create a Client ID, you will need to have an Adobe ID. If you don’t have one, you can sign up here using an email address, Google, Facebook, or Apple ID.
- You need to set your application domain in order for this to work.
Once you create your Client ID, you will want to copy and use that in your code.
NOTE: While you can edit your configurations in the Adobe.io Console, you will want to go to the link to create your key. If you create your key from within the Adobe.io Console, it won’t give you the option to set your domain.
Choosing your embed mode
One of the powerful things about the Adobe DC View SDK is that you have different embed modes to choose from:
Full Window allows you to take a viewing experience similar to Adobe Acrobat Reader on your computer and embed it into your website. I find this ideal when viewing long-form documents, or if I want to have a familiar PDF viewing experience in my UI.
Sized containers are great for content such as PowerPoint presentations that were converted to PDF, or a series of instructions. I find this less ideal of an experience if you are incorporating long-form PDFs.
In-Line view can help designers embed their designs into a web page without having to rebuild it or flatten it into an image. In-Line view takes your PDF and renders it inline as HTML. I like this embed mode for when you want to display content like infographics that you designed in Illustrator, InDesign, etc. and exported to PDF, but want it to still be searchable and have hyperlinks without having to worry of re-designing for web.
Generating your code
When you’re using Demo Site and you click on Generate code, it will look something like this:
To get started, you will want to replace the following items:
- Replace <YOUR_CLIENT_ID> with the Client ID that you generated.
- Replace the url parameter with the URL of your PDF you want to view.
NOTE: Because Adobe DC View SDK renders client-side in browser, it will honor any Cross-Domain restrictions set, so you may need to ensure your headers allow cross-domain linking.
- Change fileName to the name of your document. This will appear in the viewer.
Once you do that, you’ll be able to embed your PDF into your website. It’s that easy!
Examples that use DC Services today
There are a number of applications that already use DC services today:
Adobe DC View SDK really allows for a lot of flexibility to leverage PDFs with you websites. There is a lot more you can do with it from Analytics, Event Listeners, and more which you can learn more about in this documentation.
