image-to-pdf

Welcome to image-to-pdf 👋

A simple 🖼️ to 📄 converter for NodeJS

---

Instalation

npm install image-to-pdf

Example (CommonJS)

const { convert, sizes } = require('image-to-pdf');
const fs = require('fs')

const pages = [
    "./pages/image1.jpeg", // path to the image
    "data:image/png;base64,iVBORw...", // base64
    fs.readFileSync('./pages/image3.png') // Buffer
]
 
convert(pages, sizes.A4).pipe(fs.createWriteStream('output.pdf'))

Example (ECMAScript)

import imageToPDF, { sizes } from 'image-to-pdf';
import fs from 'fs';

let pages = fs.readdirSync('./img').map(file => `./img/${file}`);

imageToPDF(pages, sizes.A4).pipe(fs.createWriteStream('output-esm.pdf'));

Example (TypeScript)

const imageToPDF = require('image-to-pdf').default;
const fs = require('fs');

let pages: string[] = fs.readdirSync('./img').map((file: string) => `./img/${file}`);
// Alternatively you can also pass the size as a string like this:
imageToPDF(pages, 'A4').pipe(fs.createWriteStream('output-ts.pdf'));

Documentation

Accepted formats

The only accepted image formats are png and jpeg. They can be passed to the function as base64, Buffer or simply as a path to the file (see Example).

Page size

A list of all size presets in sizes can be found here. A custom size can be passed to the function simply as [x, y].

Output

The function returns a Stream (see official documentation). The easiest way to get a file is to pipe it into a WriteStream (see Example).
