convert(pages, sizes.A4).pipe(fs.createWriteStream('output.pdf'))
`

Example (ECMAScript)


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

Documentation

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).

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].

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