A react native PDF view component (cross-platform support)


  • read a PDF from url/local file/asset and can cache it.
  • display horizontally or vertically
  • drag and zoom
  • first tap for reset zoom and continuous tap for zoom in
  • support password protected pdf


We use react-native-fetch-blob to handle file system access in this package, So you should install react-native-pdf and react-native-fetch-blob

npm install react-native-pdf --save
npm install react-native-fetch-blob --save
react-native link react-native-pdf
react-native link react-native-fetch-blob


Q1. After installation and running, I can not see the pdf file. A1: maybe you forgot to excute react-native link or it does not run correctly. You can add it manually. For detail you can see the issue #24 and #2

Q2. When running, it shows 'Pdf' has no propType for native prop RCTPdf.acessibilityLabel of native type 'String' A2. Your react-native version is too old, please upgrade it to 0.47.0+ see also #39
