Multi-Format PDF Thumbnail Generator

Build a tool that converts the first page of a PDF document into multiple image formats for different use cases.

Requirements

Create a command-line tool that:

1. Takes a PDF file path as input
2. Converts the first page to three different image formats:
   • PNG format for web display
   • JPEG format for email attachments
   • WebP format for modern web applications
3. Saves all three image files to an output directory with descriptive names

The tool should accept the PDF path as a command-line argument and create the output directory if it doesn't exist.

Implementation

@generates

API

/**
 * Converts the first page of a PDF to multiple image formats
 * @param {string} pdfPath - Path to the PDF file
 * @param {string} outputDir - Directory to save the images
 * @returns {Promise<Object>} Object containing paths to generated images
 */
async function convertToMultipleFormats(pdfPath, outputDir);

• Given a valid PDF file, it creates PNG, JPEG, and WebP versions of the first page @test
• The output directory is created if it doesn't exist @test
• All three image files are saved with correct file extensions @test
