Display PDFs in your React app as easily as if they were images.
- Install by executing
npm install react-pdforyarn add react-pdf. - Import by adding
import { Document } from 'react-pdf'. - Use by adding
<Document file="..." />.filecan be a URL, base64 content, Uint8Array, and more. - Put
<Page />components inside<Document />to render pages.
Minimal demo page is included in sample directory.
Online demo is also available!
React-PDF is under constant development. This documentation is written for React-PDF 4.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:
To use the latest version of React-PDF, your project needs to use React 16.3 or later.
If you use older version of React, please refer to the table below to 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 | 4.x |
| ≥15.5 | 3.x |
| ≥0.13 | 0.0.10 |
| ≥0.11 | 0.0.4 |
Add React-PDF to your project by executing npm install react-pdf or yarn add react-pdf.
Here's an example of basic usage:
import React, { Component } from 'react';
import { Document, Page } from 'react-pdf';
class MyApp extends Component {
state = {
numPages: null,
pageNumber: 1,
}
onDocumentLoadSuccess = ({ numPages }) => {
this.setState({ numPages });
}
render() {
const { pageNumber, numPages } = this.state;
return (
<div>
<Document
file="somefile.pdf"
onLoadSuccess={this.onDocumentLoadSuccess}
>
<Page pageNumber={pageNumber} />
</Document>
<p>Page {pageNumber} of {numPages}</p>
</div>
);
}

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.
Instead of directly importing/requiring 'react-pdf', import it like so:
import { Document } from 'react-pdf/dist/entry.webpack';Instead of directly importing/requiring 'react-pdf', import it like so:
import { Document } from 'react-pdf/dist/entry.parcel';Create React App uses Webpack under the hood, but instructions for Webpack will not work. Standard instructions apply.
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.
Alternatively, you could use pdf.worker.js from an external CDN:
import { pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = `//cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjs.version}/pdf.worker.js`;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:
import 'react-pdf/dist/Page/AnnotationLayer.css';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.
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.
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/'
},
]),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.
Now that you have cMaps in your build, pass required options to Document component by using options prop, like so:
<Document
options={{
cMapUrl: 'cmaps/',
cMapPacked: true,
}}
/>Loads a document passed using file prop.
| Prop name | Description | Example values |
|---|---|---|
| className | Defines custom class name(s), that will be added to rendered element along with the default react-pdf__Document. |
|
| error | Defines what the component should display in case of an error. Defaults to "Failed to load PDF file.". |
|
| externalLinkTarget | Defines link target for external links rendered in annotations. Defaults to unset, which means that default behavior will be used. | One of valid values for target attribute.
|
| file | Defines what PDF should be displayed. Its value can be an URL, a file (imported using import ... from ... or from file input form element), or an object with parameters (url - URL; data - data, preferably Uint8Array; range - PDFDataRangeTransport; httpHeaders - custom request headers, e.g. for authorization), withCredentials - a boolean to indicate whether or not to include cookies in the request (defaults to false). |
|
| inputRef | A function that behaves like ref, but it's passed to main <div> rendered by <Document> component. |
(ref) => { this.myDocument = ref; } |
| loading | Defines what the component should display while loading. Defaults to "Loading PDF…". |
|
| noData | Defines what the component should display in case of no data. Defaults to "No PDF file specified.". |
|
| onItemClick | Function called when an outline item has been clicked. Usually, you would like to use this callback to move the user wherever they requested to. | ({ pageNumber }) => alert('Clicked an item from page ' + pageNumber + '!') |
| onLoadError | Function called in case of an error while loading a document. | (error) => alert('Error while loading document! ' + error.message) |
| onLoadSuccess | Function called when the document is successfully loaded. | (pdf) => alert('Loaded a file with ' + pdf.numPages + ' pages!') |
| onPassword | Function called when a password-protected PDF is loaded. Defaults to a function that prompts the user for password. | (callback) => callback('s3cr3t_p4ssw0rd') |
| onSourceError | Function called in case of an error while retrieving document source from file prop. |
(error) => alert('Error while retrieving document source! ' + error.message) |
| onSourceSuccess | Function called when document source is successfully retrieved from file prop. |
() => alert('Document source retrieved!') |
| options | An object in which additional parameters to be passed to PDF.js can be defined. For a full list of possible parameters, check PDF.js documentation on DocumentInitParameters. | { cMapUrl: 'cmaps/', cMapPacked: true } |
| renderMode | Defines the rendering mode of the document. Can be canvas, svg or none. Defaults to canvas. |
"svg" |
| rotate | Defines the rotation of the document in degrees. If provided, will change rotation globally, even for the pages which were given rotate prop of their own. 90 = rotated to the right, 180 = upside down, 270 = rotated to the left. |
90 |
Displays a page. Should be placed inside <Document />. Alternatively, it can have pdf prop passed, which can be obtained from <Document />'s onLoadSuccess callback function, however some advanced functions like linking between pages inside a document may not be working correctly.
| Prop name | Description | Example values |
|---|---|---|
| className | Defines custom class name(s), that will be added to rendered element along with the default react-pdf__Page. |
|
| customTextRenderer | A function that customizes how a text layer is rendered. Passes itext item and index for item. | ({ str, itemIndex }) => { return (<mark>{str}</mark>) } |
| error | Defines what the component should display in case of an error. Defaults to "Failed to load the page.". |
|
| height | Defines the height of the page. If neither height nor width are defined, page will be rendered at the size defined in PDF. If you define width and height at the same time, height will be ignored. If you define height and scale at the same time, the height will be multiplied by a given factor. |
