Node.js utility to convert PDF file/buffer pages to PNG files/buffers without binary and OS dependencies (except macOS on arm64). | ||
A Node.js utility to convert PDF file/buffer pages to PNG files/buffers without binary and OS dependencies. This utility is ideal for applications that need to process and convert PDF documents into image formats for easier viewing, sharing, or further image processing. It supports various options for rendering fonts, handling encrypted PDFs, and specifying output details, making it a versatile tool for developers working with PDF files in different environments. | ||
