PDF reader for Expo

Android support 🚀

npm version

💥 DEMO 💥

Read a PDF just with JS (no native libs needed)


  • Display file only on full screen.
  • Embeded images binary are not display (yet) in Android

PRs are welcome...


import React from 'react';
import { StyleSheet, View } from 'react-native';
import PDFReader from 'rn-pdf-reader-js';
import { Constants } from 'expo';

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
          source={{ uri: "" }}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    paddingTop: Constants.statusBarHeight,
    backgroundColor: '#ecf0f1',


  • source: Object
    • uri?: string - can be local or served on the web (ie. start withs https:// or file://)
    • base64?: string - should start with data:application/pdf;base64,. A base64 encoded pdf file tends to start with JVBERi0xL so your complete string should look soemthing like this: data:application/pdf;base64,JVBERi0xL...
  • style: object - style props to override default container style
  • webviewStyle: object - style props to override default WebView style
  • onLoad: func - callback that runs after WebView is loaded
  • noLoader: boolean - show/hide the ActivityIndicator. Default is false


  • Use it into Expo app (from expo client, Standalone app or ExpoKit app).
  • Because we need to have access to Expo.FileSystem
  • Only React-Native 0.54+ support, Expo SDK 27


  • For Android, use react-pdf / pdfjs in the webview
  • For iOS devices, display file directly to the WebView

What rn-pdf-reader-js use?

  • react-pdf (pdf.js)
  • WebView
  • Expo FileSystem API
  • Base64
