How to display PDF file in HTML?

I have an auto generated PDF file by itext and I need to display that PDF file in HTML. My question is: How to display a local PDF file in HTML using pdf.js? Should that PDF file be generated by some standards?

Implementation of a PDF file in your HTML web-page is very easy.

Make sure to change the width and height for your needs.

I use Google Docs embeddable PDF viewer. The docs don’t have to be uploaded to Google Docs, but they do have to be available online.

You need to use iframe together with google docs viewer otherwise you might get an «Error detected by the Application Firewall» message, depending on your hosting.

Just a further comment, if you want to embed a pdf file in the google drive. After clicking into the pdf, find «Embed item» it will generate the iframe HTML.

1. Browser-native HTML inline embedding:

2. Google Docs Viewer:

3. Other solutions to embed PDF:

IMPORTANT NOTE:

Please check the X-Frame-Options HTTP response header. It should be SAMEORIGIN.

Thanks for summary! I started with pdfobject just to find out it’s not a rendering solution, continued with pdf.js to find out that it doesn’t render my pdfs well on mobile and ended up with google viewer that worker flawlessly.

If you want to use pdf.js, I suggest you to read THIS

You can also upload your pdf somewhere (like Google Drive) and use its URL in a iframe

How to Embed PDF in HTML
There are several ways to include a PDF file in your HTML document:

How to embed PDF viewer in HTML
You could try embedding the PDF file in an ‘object’ tag. Here is an example of how to do this:
Example of adding a PDF file to the HTML by using the ‘object’ tag:
html> html> head> title>PDF Example by Object Tag title> head> body> h1>PDF Example by Object Tag h1> object data="/uploads/media/default/0001/01/540cb75550adf33f281f29132dddd14fded85bfc.pdf" type="application/pdf" width="100%" height="500px"> p>Unable to display PDF file. a href="/uploads/media/default/0001/01/540cb75550adf33f281f29132dddd14fded85bfc.pdf">Download a> instead. p> object> body> html>
This code will display the PDF file in an object element in the HTML page. If the browser is unable to display the PDF file, it will show a fallback message with a download link.
Can we prevent the pdf from downloading?
Unfortunately, it is not possible to completely prevent a user from downloading a PDF file that is embedded in an HTML page. Even if you disable the right-click context menu, a user can still access the PDF file through the browser’s developer tools or by inspecting the page source.
However, you can make it more difficult for a user to download the PDF file by using various methods, such as:

Converting the PDF file to an image format (such as JPEG or PNG) using a tool like ImageMagick or Ghostscript, and displaying the images in an HTML page. This way, the user will not be able to download the original PDF file directly, but they can still download the images.
Using a JavaScript PDF viewer library like PDF.js, which can display PDF files in an HTML page using the browser’s built-in PDF rendering capabilities. You can customize the viewer to disable downloading and printing, but as I mentioned earlier, it is still possible for a user to access the PDF file through the browser’s developer tools or by inspecting the page source.
An alternative strategy to consider is the use of CloudPDF, a unique cloud-based service designed specifically to protect PDF files from unauthorized downloads. Similar to PDF.js, CloudPDF provides a platform for viewing PDF files within the browser, but sets itself apart by disabling the download functionality for viewers, adding an extra layer of document control. CloudPDF achieves this through server-side rendering, a technique that prevents the PDF from being directly transferred or displayed in the client’s browser, making it more difficult for the document to be accessed via developer tools or page source inspection, thereby enhancing security significantly. While it’s important to note that no method is foolproof, the features provided by CloudPDF notably elevate the difficulty level for unauthorized access, making it a worthy consideration for those seeking enhanced document security.

How to View a PDF in HTML
PDF documents are used all across the internet. Be it an invoice from an online shop, or a sales agreement, PDF is everywhere. One of the main arguments for using PDF as opposed to word processor files is the fact that the PDF file format is rendered exactly the same no matter the device. This trait is especially useful on the web, where getting something to look the same on different browsers isn’t always easy.
In this article, we’ll look at a simple approach for showing PDFs in an HTML app without using JavaScript by making use of the and HTML5 elements. This option works regardless of the programming language you’re using — no matter if you’re an ASP.NET, JavaScript, PHP, C++, Java, Python, or Ruby specialist.
Embedding a PDF in HTML with an Object Element
Given the immense popularity of PDF, it’s no wonder that all common browsers (Google Chrome, Firefox, Internet Explorer, Edge, and Safari) include some sort of built-in PDF support. This makes it possible to embed PDFs into HTML pages without using JavaScript. Let’s explore the most common method to do so.
The HTML element can use a native browser for PDF viewing, and it even allows you to provide a fallback if PDF isn’t supported. It doesn’t require JavaScript and is a common tool when working on an HTML5 application:
Embedding a PDF in HTML with an iframe Element
Since isn’t available in every browser, this method is often combined with the HTML element to reach the most users. To do this, the fallback area of the is used to host an . Similar to the element, the content of an — in our case, this would be the 
tag with its content — is only shown when the browser doesn’t support PDFs via the element:
Live Example
If you’re curious how the above PDF will be rendered in your browser, check out the following example integration:
These simple HTML elements work in most desktop browsers and can be used to add PDF support to your web app without relying on JavaScript.
Problems with This Approach
This approach of displaying PDF documents is fast and requires no programming. There are, however, certain downsides:

A browser could use whichever PDF reader is installed on a system, and there’s no API that would allow you to customize the reader’s look and feel. In other words, the UI used when loading a PDF via an is completely outside of your control.
It isn’t guaranteed that every browser will implement a PDF view via or . For example, certain versions of Internet Explorer will require your users to install Adobe Reader to support rendering a PDF via , whereas other browsers might not support it at all.
There’s only a very limited set of API methods. In fact, if you look closely at the data and src properties in the above examples, you can see we’ve appended #page=2 to the URLs. This allows you to control the page that’s shown. If you’re looking for a complete reference of parameters, check out the Parameters for Opening PDF Files specification published by Adobe in 2007. Unfortunately, supporting those parameters isn’t required, and thus, there’s no guarantee that this flag really works (as an example, while writing this, we noticed Safari 11 doesn’t seem to honor any of the mentioned properties).

Conclusion
With the or HTML5 elements, it’s possible to show a PDF in your web app with ease. This is supported in most browsers and requires no JavaScript at all, making it a perfect approach for adding PDF support if no advanced features are necessary.
However, for use cases that require support for every browser, customization, or some of the more advanced PDF features — such as PDF annotations, interactive PDF forms, digital signatures, and more — we recommend you look into commercial alternatives.
At PSPDFKit, we offer a commercial, feature-rich, and completely customizable HTML5 PDF Viewer Library that’s easy to integrate and comes with well-documented APIs to handle complex use cases. Try out our PDF library using our free trial, and check out our demos to see what’s possible.
