PDF.js
PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.
PDF.js is community-driven and supported by Mozilla Labs. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.

Getting Started
Online demo
Browser Extensions
Firefox (and Seamonkey)
PDF.js is built into version 19+ of Firefox, however, one extension is still available:
- Development Version – This extension is mainly intended for developers/testers, and it is updated every time new code is merged into the PDF.js codebase. It should be quite stable but might break from time to time.
- Please note that the extension is not guaranteed to be compatible with Firefox versions that are older than the current ESR version, see the Release Calendar.
- The extension should also work in Seamonkey, provided that it is based on a Firefox version as above (see Which version of Firefox does SeaMonkey 2.x correspond with?), but we do not guarantee compatibility.
Chrome
- The official extension for Chrome can be installed from the Chrome Web Store. This extension is maintained by @Rob–W.
- Build Your Own – Get the code as explained below and issue
gulp chromium
. Then open Chrome, go toTools > Extension
and load the (unpackaged) extension from the directorybuild/chromium
.Getting the Code
To get a local copy of the current code, clone it using git:
$ git clone git://github.com/mozilla/pdf.js.git $ cd pdf.js
Next, install Node.js via the official package or via nvm. You need to install the gulp package globally (see also gulp’s getting started):
$ npm install -g gulp-cli
If everything worked out, install all dependencies for PDF.js:
$ npm install
Finally, you need to start a local web server as some browsers do not allow opening PDF files using a
file://
URL. Run:$ gulp server
and then you can open:
Please keep in mind that this requires an ES6 compatible browser; refer to Building PDF.js for usage with older browsers.
It is also possible to view all test PDF files on the right side by opening:
Building PDF.js
In order to bundle all
src/
files into two production scripts and build the generic viewer, run:$ gulp generic
This will generate
pdf.js
andpdf.worker.js
in thebuild/generic/build/
directory. Both scripts are needed but onlypdf.js
needs to be included sincepdf.worker.js
will be loaded bypdf.js
. The PDF.js files are large and should be minified for production.Using PDF.js in a web application
To use PDF.js in a web application you can choose to use a pre-built version of the library or to build it from source. We supply pre-built versions for usage with NPM and Bower under the
pdfjs-dist
name. For more information and examples please refer to the wiki page on this subject.Learning
You can play with the PDF.js API directly from your browser using the live demos below:
The repository contains a hello world example that you can run locally:
More examples can be found in the examples folder. Some of them are using the pdfjs-dist package, which can be built and installed in this repo directory via
gulp dist-install
command.For an introduction to the PDF.js code, check out the presentation by our contributor Julian Viereck:

传统的在网页中打开pdf文件,基本上是通过flash实现的。不过最近我接触到了pdf.js,发现一切都变了。

pdf.js 是一个技术原型主要用于在 HTML5 平台上展示 PDF 文档,无需任何本地技术支持。
如何使用呢?由于本人技术有限,只解决了百分之一的使用场景。
在web目录下面有一个viewer.js。里面定义了打开pdf的路径。修改里面的路径即可定向的浏览某pdf。
