@file-type/pdf

Detector plugin for file-type that identifies
PDF (Portable Document Format) files and selected PDF-based subtypes.

This plugin goes beyond simple magic-number detection and can inspect the internal PDF
structure to distinguish between generic PDF files and specific producer formats such as
Adobe Illustrator (.ai).

Scope

This detector is designed for well-formed PDF files and established PDF-based subtypes.
Support for corrupted or non-conforming PDFs is intentionally limited and only considered when a deviation is both common and widely accepted.

Installation

``bash
npm install @file-type/pdf
`

Usage

The following example shows how to add the PDF detector to file-type:

`js
import { FileTypeParser } from 'file-type';
import { detectPdf } from '@file-type/pdf';

const parser = new FileTypeParser({
customDetectors: [detectPdf],
});

const fileType = await parser.fromFile('example.pdf');
console.log(fileType);
`

Supported file formats

- .ai / application/illustrator: Adobe Illustrator
- .pdf / application/pdf`: Generic Portable Document Format files
