react-native-images-to-pdf

badge

Easily generate PDF files from images in React Native.

iOS Android

Installation

npm install react-native-images-to-pdf

or

yarn add react-native-images-to-pdf

iOS

Run pod install in the ios directory.

Usage

Example using react-native-blob-util

import { createPdf } from 'react-native-images-to-pdf';
import RNBlobUtil from 'react-native-blob-util';

const options = {
  pages: [
    { imagePath: '/path/to/image1.jpg' },
    { imagePath: '/path/to/image2.jpg' }
  ],
  outputPath: `file://${RNBlobUtil.fs.dirs.DocumentDir}/file.pdf`,
};

createPdf(options)
  .then((path) => console.log(`PDF created successfully: ${path}`))
  .catch((error) => console.log(`Failed to create PDF: ${error}`));

This example is using react-native-blob-util to get a valid outputPath, but you can choose any other library to achieve the same functionality.

Example using react-native-document-scanner-plugin

import { createPdf } from 'react-native-images-to-pdf';
import DocumentScanner from 'react-native-document-scanner-plugin';

DocumentScanner.scanDocument()
  .then(({scannedImages}) => {
    if (!scannedImages?.length) {
      throw new Error('No images scanned');
    }

    return createPdf({
      pages: scannedImages.map(imagePath => ({ imagePath })),
      outputPath: `file:///path/to/output/file.pdf`,
    });
  })
  .then(path => console.log(`PDF created successfully: ${path}`))
  .catch(error => console.log(`Failed to create PDF: ${error}`));
