This package is used to _display_ existing PDFs. If you wish to _create_ PDFs using React, you may be looking for [@react-pdf/renderer](https://www.npmjs.com/package/@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](https://projects.wojtekmaj.pl/react-pdf/) is also available! ## Before you continue React-PDF is under constant development. This documentation is written for React-PDF 9.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: - [v8.x](https://github.com/wojtekmaj/react-pdf/blob/v8.x/packages/react-pdf/README.md) - [v7.x](https://github.com/wojtekmaj/react-pdf/blob/v7.x/packages/react-pdf/README.md) - [v6.x](https://github.com/wojtekmaj/react-pdf/blob/v6.x/README.md) - [v5.x](https://github.com/wojtekmaj/react-pdf/blob/v5.x/README.md) - [v4.x](https://github.com/wojtekmaj/react-pdf/blob/v4.x/README.md) - [v3.x](https://github.com/wojtekmaj/react-pdf/blob/v3.x/README.md) - [v2.x](https://github.com/wojtekmaj/react-pdf/blob/v2.x/README.md) - [v1.x](https://github.com/wojtekmaj/react-pdf/blob/v1.x/README.md) ## Getting started ### Compatibility #### Browser support React-PDF supports all modern browsers. It is tested with the latest versions of Chrome, Edge, Safari, Firefox, and Opera. The following browsers are supported out of the box in React-PDF v9: - Chrome ≥119 - Edge ≥119 - Safari ≥17.4 - Firefox ≥121 You may extend the list of supported browsers by providing additional polyfills (e.g. for `Array.prototype.at`, `Promise.allSettled` or `Promise.withResolvers`) and either configuring your bundler to transpile `pdfjs-dist` or using [legacy PDF.js worker](#legacy-pdfjs-worker). If you need to support older browsers, you will need to use React-PDF v6 or earlier. #### React To use the latest version of React-PDF, your project needs to use React 16.8 or later. If you use an older version of React, please refer to the table below to a find suitable React-PDF version. | React version | Newest compatible React-PDF version | | ------------- | ----------------------------------- | | ≥16.8 | latest | | ≥16.3 | 5.x | | ≥15.5 | 4.x | #### Preact React-PDF may be used with Preact. ### Installation Add React-PDF to your project by executing `npm install react-pdf` or `yarn add react-pdf`. #### Next.js If you use Next.js without Turbopack enabled, add the following to your `next.config.js`: ```diff module.exports = { + webpack: (config) => { + config.resolve.alias.canvas = false; + return config; + }, } ``` If you use Next.js with Turbopack enabled, add `empty-module.ts` file: ```ts export default {}; ``` and add the following to your `next.config.js`: ```diff module.exports = { + experimental: { + turbo: { + resolveAlias: { + canvas: './empty-module.ts', + }, + }, + }, }; ``` If you use Next.js prior to v15 (v15.0.0-canary.53, specifically), you may need to add the following to your `next.config.js`: ```diff module.exports = { + swcMinify: false, } ``` ### Configure PDF.js worker For React-PDF to work, PDF.js worker needs to be provided. You have several options. #### Import worker (recommended) For most cases, the following example will work: ```ts import { pdfjs } from 'react-pdf'; pdfjs.GlobalWorkerOptions.workerSrc = new URL( 'pdfjs-dist/build/pdf.worker.min.mjs', import.meta.url, ).toString(); ``` > [!NOTE] > In Next.js: > > - Using App Router, make sure to add `'use client';` to the top of the file. > - Using Pages Router, make sure to [disable SSR](https://nextjs.org/docs/pages/building-your-application/optimizing/lazy-loading#with-no-ssr) when importing the component you're using this code in. > [!NOTE] > pnpm requires an `.npmrc` file with `public-hoist-pattern[]=pdfjs-dist` for this to work.

See more examples

##### Parcel 2 For Parcel 2, you need to use a slightly different code: ```diff pdfjs.GlobalWorkerOptions.workerSrc = new URL( - 'pdfjs-dist/build/pdf.worker.min.mjs', + 'npm:pdfjs-dist/build/pdf.worker.min.mjs', import.meta.url, ).toString(); ```

#### Copy worker to public directory You will have to make sure on your own that `pdf.worker.mjs` file from `pdfjs-dist/build` is copied to your project's output folder. For example, you could use a custom script like: ```ts import path from 'node:path'; import fs from 'node:fs'; const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json')); const pdfWorkerPath = path.join(pdfjsDistPath, 'build', 'pdf.worker.mjs'); fs.cpSync(pdfWorkerPath, './dist/pdf.worker.mjs', { recursive: true }); ``` #### Use external CDN ```ts import { pdfjs } from 'react-pdf'; pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.mjs`; ``` #### Legacy PDF.js worker If you need to support older browsers, you may use legacy PDF.js worker. To do so, follow the instructions above, but replace `/build/` with `legacy/build/` in PDF.js worker import path, for example: ```diff pdfjs.GlobalWorkerOptions.workerSrc = new URL( - 'pdfjs-dist/build/pdf.worker.min.mjs', + 'pdfjs-dist/legacy/build/pdf.worker.min.mjs', import.meta.url, ).toString(); ``` or: ```diff -pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.mjs`; +pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/legacy/build/pdf.worker.min.mjs`; ``` ### Usage Here's an example of basic usage: ```tsx import { useState } from 'react'; import { Document, Page } from 'react-pdf'; function MyApp() { const [numPages, setNumPages] = useState(); const [pageNumber, setPageNumber] = useState(1); function onDocumentLoadSuccess({ numPages }: { numPages: number }): void { setNumPages(numPages); } return (

Page {pageNumber} of {numPages}

); } ``` Check the [sample directory](https://github.com/wojtekmaj/react-pdf/tree/main/sample) in this repository for a full working example. For more examples and more advanced use cases, check [Recipes](https://github.com/wojtekmaj/react-pdf/wiki/Recipes) in [React-PDF Wiki](https://github.com/wojtekmaj/react-pdf/wiki/). ### 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: ```ts import 'react-pdf/dist/Page/AnnotationLayer.css'; ``` ### Support for text layer If you want to use text layer in PDFs rendered by React-PDF, then you would need to include stylesheet necessary for text layer to be correctly displayed like so: ```ts import 'react-pdf/dist/Page/TextLayer.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`. ##### Vite Add [`vite-plugin-static-copy`](https://www.npmjs.com/package/vite-plugin-static-copy) by executing `npm install vite-plugin-static-copy --save-dev` or `yarn add vite-plugin-static-copy --dev` and add the following to your Vite config: ```diff +import path from 'node:path'; +import { createRequire } from 'node:module'; -import { defineConfig } from 'vite'; +import { defineConfig, normalizePath } from 'vite'; +import { viteStaticCopy } from 'vite-plugin-static-copy'; +const require = createRequire(import.meta.url); + +const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json')); +const cMapsDir = normalizePath(path.join(pdfjsDistPath, 'cmaps')); export default defineConfig({ plugins: [ + viteStaticCopy({ + targets: [ + { + src: cMapsDir, + dest: '', + }, + ], + }), ] }); ``` ##### Webpack Add [`copy-webpack-plugin`](https://www.npmjs.com/package/copy-webpack-plugin) by executing `npm install copy-webpack-plugin --save-dev` or `yarn add copy-webpack-plugin --dev` and add the following to your Webpack config: ```diff +import path from 'node:path'; +import CopyWebpackPlugin from 'copy-webpack-plugin'; +const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json')); +const cMapsDir = path.join(pdfjsDistPath, 'cmaps'); module.exports = { plugins: [ + new CopyWebpackPlugin({ + patterns: [ + { + from: cMapsDir, + to: 'cmaps/' + }, + ], + }), ], }; ``` ##### Other tools If you use other bundlers, you will have to make sure on your own that cMaps are copied to your project's output folder. For example, you could use a custom script like: ```ts import path from 'node:path'; import fs from 'node:fs'; const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json')); const cMapsDir = path.join(pdfjsDistPath, 'cmaps'); fs.cpSync(cMapsDir, 'dist/cmaps/', { recursive: true }); ``` #### Setting up React-PDF Now that you have cMaps in your build, pass required options to Document component by using `options` prop, like so: ```ts // Outside of React component const options = { cMapUrl: '/cmaps/', }; // Inside of React component ; ``` > [!NOTE] > Make sure to define `options` object outside of your React component, and use `useMemo` if you can't. Alternatively, you could use cMaps from external CDN: ```tsx // Outside of React component import { pdfjs } from 'react-pdf'; const options = { cMapUrl: `https://unpkg.com/pdfjs-dist@${pdfjs.version}/cmaps/`, }; // Inside of React component ; ``` ### Support for standard fonts If you want to support PDFs using standard fonts (deprecated in PDF 1.5, but still around), ot you have encountered the following warning: ``` The standard font "baseUrl" parameter must be specified, ensure that the "standardFontDataUrl" API parameter is provided. ``` then you would also need to include standard fonts in your build and tell React-PDF where they are. #### Copying fonts First, you need to copy standard fonts from `pdfjs-dist` (React-PDF's dependency - it should be in your `node_modules` if you have React-PDF installed). Standard fonts are located in `pdfjs-dist/standard_fonts`. ##### Vite Add [`vite-plugin-static-copy`](https://www.npmjs.com/package/vite-plugin-static-copy) by executing `npm install vite-plugin-static-copy --save-dev` or `yarn add vite-plugin-static-copy --dev` and add the following to your Vite config: ```diff +import path from 'node:path'; +import { createRequire } from 'node:module'; -import { defineConfig } from 'vite'; +import { defineConfig, normalizePath } from 'vite'; +import { viteStaticCopy } from 'vite-plugin-static-copy'; +const require = createRequire(import.meta.url); +const standardFontsDir = normalizePath( + path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'standard_fonts') +); export default defineConfig({ plugins: [ + viteStaticCopy({ + targets: [ + { + src: standardFontsDir, + dest: '', + }, + ], + }), ] }); ``` ##### Webpack Add [`copy-webpack-plugin`](https://www.npmjs.com/package/copy-webpack-plugin) by executing `npm install copy-webpack-plugin --save-dev` or `yarn add copy-webpack-plugin --dev` and add the following to your Webpack config: ```diff +import path from 'node:path'; +import CopyWebpackPlugin from 'copy-webpack-plugin'; +const standardFontsDir = path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'standard_fonts'); module.exports = { plugins: [ + new CopyWebpackPlugin({ + patterns: [ + { + from: standardFontsDir, + to: 'standard_fonts/' + }, + ], + }), ], }; ``` ##### Other tools If you use other bundlers, you will have to make sure on your own that standard fonts are copied to your project's output folder. For example, you could use a custom script like: ```ts import path from 'node:path'; import fs from 'node:fs'; const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json')); const standardFontsDir = path.join(pdfjsDistPath, 'standard_fonts'); fs.cpSync(standardFontsDir, 'dist/standard_fonts/', { recursive: true }); ``` #### Setting up React-PDF Now that you have standard fonts in your build, pass required options to Document component by using `options` prop, like so: ```tsx // Outside of React component const options = { standardFontDataUrl: '/standard_fonts/', }; // Inside of React component ; ``` > [!NOTE] > Make sure to define `options` object outside of your React component, and use `useMemo` if you can't.
