How To Display Whole Pdf Not Only One Page With Pdf Js

Are you using PDF.js for displaying PDF files on your website but struggling to show the entire PDF instead of just one page? Don't worry; we've got you covered with this step-by-step guide on how to display the whole PDF using PDF.js.

PDF.js is a popular JavaScript library for rendering PDF files in the browser. By default, PDF.js only displays one page of the PDF at a time, which can be limiting if you want to show the entire document at once. However, with a few tweaks, you can configure PDF.js to display the whole PDF document seamlessly.

First, ensure you have included the PDF.js library in your project. If you haven't already done so, you can easily add it by downloading the library from the official GitHub repository or using a package manager like npm or yarn.

Once you have PDF.js set up in your project, you can follow these steps to display the entire PDF file:

1. Load the PDF File:
The first step is to load the PDF file using PDF.js. You can do this by providing the URL of the PDF file you want to display. PDF.js will fetch the file and render it on the webpage.

Javascript

// Load the PDF file
const loadingTask = pdfjsLib.getDocument('path/to/your/file.pdf');

loadingTask.promise.then((pdf) =&gt; {
  // Display the first page
  renderPage(pdf, 1);
});

2. Render All Pages:
To display all pages of the PDF file, you need to modify the rendering function to iterate through all pages and render them one by one. You can use a loop to render each page sequentially.

Javascript

// Render all pages
function renderAllPages(pdf) {
  for (let pageNum = 1; pageNum  {
      renderPage(page);
    });
  }
}

function renderPage(page) {
  // Rendering logic for a single page
}

3. Adjust the Viewer:
You may need to adjust the viewer to accommodate the entire PDF document. This could involve resizing the viewer container or implementing navigation controls to allow users to navigate through the pages easily.

By following these steps, you can modify PDF.js to display the complete PDF document instead of just one page. This will enhance the user experience and make it easier for visitors to view the entire content without interruption.

In conclusion, displaying the entire PDF document with PDF.js is achievable with a few modifications to the default setup. By loading the PDF file, rendering all pages, and adjusting the viewer as needed, you can showcase the complete document seamlessly. Implement these steps in your project to enhance the PDF viewing experience for your users. Happy coding!
