How to display pdf file in html?

Displaying a PDF file in HTML can be done in several ways. The simplest way is to embed the PDF file directly within an HTML document using an iframe or object tag. Another option is to convert the PDF file into a series of images and then display each image using an img tag. In this article, we’ll cover the different methods for displaying a PDF file in HTML, including their pros and cons.

Method 1: Embedding a PDF with the tag

To display a PDF file in HTML using the tag, follow these steps:

1. Create an element in your HTML code, with a «src» attribute that points to the URL of the PDF file you want to display.

iframe src="example.pdf">iframe>

iframe src="example.pdf" width="500" height="700">iframe>

iframe src="example.pdf" width="500" height="700" allowfullscreen>iframe>

1. Optionally, you can add other attributes to the element to customize the PDF file display, such as «scrolling» to enable or disable scrolling, or «frameborder» to show or hide the frame border.

iframe src="example.pdf" width="500" height="700" allowfullscreen scrolling="no" frameborder="0">iframe>

Note that the tag is not supported in all web browsers, so you may need to use a different method to display PDF files in HTML for maximum compatibility.

Method 2: Embedding a PDF with the tag

To display a PDF file in HTML, you can use the tag to embed the PDF file within the HTML document. Here is an example code:

DOCTYPE html> html> head> title>Embedding a PDF with the object> tagtitle> head> body> h1>Embedding a PDF with the object> tagh1> object data="example.pdf" type="application/pdf" width="100%" height="600px"> p>It appears you don't have a PDF plugin for this browser. No biggie. you can a href="example.pdf">click here to download the PDF file.a>p> object> body> html>

In this example, we are using the tag with the data attribute set to the URL of the PDF file. We also set the type attribute to «application/pdf» to indicate that this is a PDF file. The width and height attributes are set to 100% and 600px, respectively, to specify the dimensions of the embedded PDF.

If the user’s browser does not have a PDF plugin, the text within the tag will be displayed, which provides a link to download the PDF file.

That’s all there is to it! By using the tag, you can easily embed a PDF file within an HTML document.

Method 3: Converting PDF to images and displaying with the tag

To display a PDF file in HTML using the tag, you can first convert the PDF to images and then display the images using the tag. Here is how you can do it in steps:

from pdf2image import convert_from_path import os

pages = convert_from_path('example.pdf', 500) for page in pages: page.save('page.jpg', 'JPEG')

img src="page.jpg" alt="PDF Page">

And that’s it! You can now display a PDF file in HTML using the tag by converting the PDF to images and displaying the images.

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:

1. 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.
2. 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.
3. 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 Embed a PDF in an HTML Website

In this article (a five-minute read), you’ll learn about two simple (and free!) approaches to displaying PDFs in the browser and how you can quickly implement them in your website.

Native Browser PDF Rendering

Since PDF is such a widely used format, all modern browsers have built-in PDF support. We can take advantage of this by using HTML elements to embed a PDF directly in our web page, like this:

DOCTYPE html> html> head> title>PDF Viewertitle> head> body>   Place the following element where you want the PDF to be displayed in your website. You can change the size using the width and height attributes. --> div> object data='https://pdfjs-express.s3-us-west-2.amazonaws.com/docs/choosing-a-pdf-viewer.pdf' type="application/pdf" width="500" height="678" > iframe src='https://pdfjs-express.s3-us-west-2.amazonaws.com/docs/choosing-a-pdf-viewer.pdf' width="500" height="678" > p>This browser does not support PDF!p> iframe> object> div> body> html> 

I’ve used a URL for the data and src values. These point to the PDF I want to open from a URL. But I could instead open a local file by swapping out the URL for a file path (e.g. /path/to/file.pdf ).

The PDF viewer’s user interface will look a bit different depending on your browser:

This approach will work in all modern desktop and mobile versions of Chrome, Safari, Firefox, and Edge. (It will not work in Internet Explorer.) If you need to support Internet Explorer or customize the user interface, you should consider the next approach — PDF.js rendering.

Embed PDF in HTML With Free PDF.js Express Viewer

PDF.js Express Viewer is a free PDF.js viewer that wraps a modern React-based UI around the open-source PDF.js rendering engine. PDF.js was originally developed by Mozilla and is maintained by an open-source community. PDF.js Express Viewer allows you to render PDFs inside a web page by using JavaScript instead of the browser’s built-in PDF support.

The benefits of PDF.js Express Viewer compared to native browser rendering are:

• Internet Explorer support (in addition to all modern browsers)
• Consistent user interface and user experience across browsers
• A more customizable user interface (for example, removing the download button)

PDF.js Express Viewer HTML Example

Here is what we will make after following this tutorial:

Adding PDF.js Express Viewer to your website is an easy 3 step process. Here we will be doing a manual integration, however, we have guides for integrating PDF.js Express Viewer with many frameworks, including React, Angular, Vue, and much more. You can find a full list of framework guides here

Step 1 — Download PDF.js Express Viewer

Note that to use the PDF.js Express Viewer you will need a free license key. Please get your free Viewer key here if you do not have one.

Step 2 — Integrate PDF.js Express into your application

DOCTYPE html> html> head> title>PDF.js Express Viewertitle> head> script src='/lib/webviewer.min.js'> script> body> >>div> body> html> 

To import PDF.js Express Viewer as a CommonJS module, please refer to this guide to integrate with NPM

Once you have done this an example project directory might look something like this:

root folder ├── images │ └── . ├── scripts │ └── . ├── styles │ └── . ├── index.html ├── lib │ ├── ui │ │ ├── . │ ├── core │ │ ├── . │ └── webviewer.min.js └── . 

In this sample directory you can add the folders: images, scripts, and styles to include any extra resources you would like to have on your website. However for this example project it is only necessary to have the extracted lib folder and the index.html file we just created in the above step.

1. To instantiate PDF.js Express Web Viewer, add this script in body after the viewer div declaration:

script> WebViewer( path: '/lib', // path to the PDF.js Express'lib' folder on your server licenseKey: 'Insert free license key here', initialDoc: 'https://pdftron.s3.amazonaws.com/downloads/pl/webviewer-demo.pdf', // initialDoc: '/path/to/my/file.pdf', // You can also use documents on your server >, document.getElementById('viewer')) .then(instance =>  // now you can access APIs through the WebViewer instance const  Core, UI > = instance; // adding an event listener for when a document is loaded Core.documentViewer.addEventListener('documentLoaded', () =>  console.log('document loaded'); >); // adding an event listener for when the page number has changed Core.documentViewer.addEventListener('pageNumberUpdated', (pageNumber) =>  console.log(`Page number is: $pageNumber>`); >); >); script> 

The easiest way to run this project would be with http-server . To do so, make sure you have Node.js installed.

Next open your terminal and install http-server with the following command:

Once installed navigate to the root of your website’s directory in the terminal and run the following command:

After running that command go to your browser and type localhost:8080. You should then see the following:

Step 3 — Use PDF.js Express Viewer APIs to customize the viewer

To use more PDF.js Express APIs, you can add the API calls in the callback of the PDF.js Express constructor. For example, to change the theme of PDF.js Express to dark, you can add:

.then((instance) =>  const  documentViewer, annotationManager > = instance.Core; // call methods from instance, documentViewer and annotationManager as needed instance.UI.setTheme('dark'); // . >); 

Refresh your application page ( http://localhost:3000/ ) and you should see the theme has changed:

For resources on how to use more of our PDF.js Express API, check out the PDF.js Express guides and API.

Conclusion

We hope this was helpful! You can also have a look at PDF.js Express Plus, which extends the functionality of PDF.js Express Viewer with PDF annotation, form filling, and signing inside your web app.
