React-PDF

Display PDFs in your React app as easily as if they were images.

Lost?

This package is used to display existing PDFs. If you wish to create PDFs using React, you may be looking for @react-pdf/renderer.

tl;dr

  • Install by executing
    npm install react-pdf
    or
    yarn add react-pdf
    .
  • Import by adding
    import { Document } from 'react-pdf'
    .
  • Use by adding
    . 
    file
    can be a URL, base64 content, Uint8Array, and more.
  • Put
     components inside 
     to render pages.

Demo

A minimal demo page can be found in

sample
directory.

Online demo is also available!

Before you continue

React-PDF is under constant development. This documentation is written for React-PDF 5.x branch. If you want to see documentation for other versions of React-PDF, use dropdown on top of GitHub page to switch to an appropriate tag. Here are quick links to the newest docs from each branch:

Getting started

Compatibility

React

To use the latest version of React-PDF, your project needs to use React 16.3 or later.

If you use an older version of React, please refer to the table below to a find suitable React-PDF version. Don't worry - as long as you're running React 15.5 or later, you won't be missing out a lot!

| React version | Newest compatible React-PDF version | |-------|--------| | ≥16.3 | latest | | ≥15.5 | 4.x |

Internet Explorer

Internet Explorer is not supported in React-PDF 5.x or later. If you need Internet Explorer support, you will need to use React-PDF 4.x instead. Don't worry - it still receives bug fixes and even occasional small features!

Installation

Add React-PDF to your project by executing

npm install react-pdf
or
yarn add react-pdf
.

Usage

Here's an example of basic usage:

import React, { useState } from 'react';
import { Document, Page } from 'react-pdf';

function MyApp() { const [numPages, setNumPages] = useState(null); const [pageNumber, setPageNumber] = useState(1);

function onDocumentLoadSuccess({ numPages }) { setNumPages(numPages); }

return (

Page {pageNumber} of {numPages}

); }

Check the sample directory in this repository for a full working example. For more examples and more advanced use cases, check Recipes in React-PDF Wiki.

Enable PDF.js worker

It is crucial for performance to use PDF.js worker whenever possible. This ensures that PDF files will be rendered in a separate thread without affecting page performance. To make things a little easier, we've prepared several entry points you can use.

Webpack

Instead of directly importing/requiring

'react-pdf'
, import it like so:
// using ES6 modules
import { Document } from 'react-pdf/dist/esm/entry.webpack';

// using CommonJS modules import { Document } from 'react-pdf/dist/umd/entry.webpack';

Parcel

Instead of directly importing/requiring

'react-pdf'
, import it like so:
// using ES6 modules
import { Document } from 'react-pdf/dist/esm/entry.parcel';

// using CommonJS modules import { Document } from 'react-pdf/dist/umd/entry.parcel';

Create React App

Create React App uses Webpack under the hood, so you can follow Webpack instructions.

Standard instructions will also work. In Create React App, you can copy

pdf.worker.js
file from
pdfjs-dist/build
to
public
directory in order for it to be copied to your project's output folder at build time.

Standard (Browserify and others)

If you use Browserify or other bundling tools, you will have to make sure on your own that

pdf.worker.js
file from
pdfjs-dist/build
is copied to your project's output folder.

If you don't need to debug

pdf.worker.js
, you can use
pdf.worker.min.js
file instead, which is roughly half the size. For this to work, however, you will need to specify
workerSrc
manually like so:
import { pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = 'pdf.worker.min.js';

Alternatively, you could use the minified

pdf.worker.min.js
from an external CDN:
import { pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = `//cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjs.version}/pdf.worker.min.js`;

Support for annotations

If you want to use annotations (e.g. links) in PDFs rendered by React-PDF, then you would need to include stylesheet necessary for annotations to be correctly displayed like so:

// using ES6 modules
import 'react-pdf/dist/esm/Page/AnnotationLayer.css';

// using CommonJS modules import 'react-pdf/dist/umd/Page/AnnotationLayer.css';

Support for non-latin characters

If you want to ensure that PDFs with non-latin characters will render perfectly, or you have encountered the following warning:

Warning: The CMap "baseUrl" parameter must be specified, ensure that the "cMapUrl" and "cMapPacked" API parameters are provided.

then you would also need to include cMaps in your build and tell React-PDF where they are.

Copying cMaps

First, you need to copy cMaps from

pdfjs-dist
(React-PDF's dependency - it should be in your
node_modules
if you have React-PDF installed). cMaps are located in
pdfjs-dist/cmaps
.
Webpack

Add

copy-webpack-plugin
to your project if you haven't already:
npm install copy-webpack-plugin --save-dev

Now, in your Webpack config, import the plugin:

import CopyWebpackPlugin from 'copy-webpack-plugin';

and in

plugins
section of your config, add the following:
new CopyWebpackPlugin([
  {
    from: 'node_modules/pdfjs-dist/cmaps/',
    to: 'cmaps/'
  },
]),
Parcel, Browserify and others

If you use Parcel, Browserify or other bundling tools, you will have to make sure on your own that cMaps are copied to your project's output folder.

Setting up React-PDF

Now that you have cMaps in your build, pass required options to Document component by using

options
prop, like so:

Alternatively, you could use cMaps from external CDN:

import { pdfjs } from 'react-pdf';

User guide

Document

Loads a document passed using

file
prop.
