const canvas = document.getElementById(' pdf') Ĭonst context = canvas.getContext(' 2d') Apply page dimensions to the `` element. const page = await pdf.getPage( 1) Ĭonst viewport = page.getViewport(scale) We also create a element, which we want the first page of the PDF to be rendered into:Ĭonst loadingTask = PDFJS.getDocument(' /test.pdf') The HTML file needs to point to the pdf.js source code and to our custom application code ( simple.js).

We move these files into a new empty directory, which allows us to create a simple.js and a simple.html file. We first extract all the files in the downloaded copy of PDF.js, but we currently only need the files pdf.js and from the build/ folder of the download.

Using the layer directly is considered advanced usage.ĭisplay - This layer builds upon the core layer and exposes an easy-to-use interface for most day-to-day work. PDF.js consists of three different layers:Ĭore - The binary format of a PDF is interpreted in this layer. To improve performance, a lot of the processing work happens in a web worker, where the work of the core layer usually takes place. With PDF.js, PDFs are downloaded via AJAX and rendered in a element using native drawing commands. We suggest carefully testing correctness, as there are many known problems with the render fidelity of PDF.js. Since it implements PDF rendering in vanilla JavaScript, it has cross-browser compatibility and doesn’t require additional plugins to be installed. PDF.js is a JavaScript library written by Mozilla. Displaying a PDF in the Browser with PDF.js We’ll walk you through how to render a PDF and how to embed a PDF viewer in the browser, and at the end, we’ll discuss cases in which you should opt for a commercial Javascript PDF Viewer. In this tutorial, we’ll go a bit deeper and examine one of the most popular open source libraries for rendering PDF files in the browser: PDF.js.
