Why You Don't Need Desktop Software for PDFs
Five years ago, merging PDFs required desktop software because browsers lacked the ability to process binary files. Today, modern browsers include:
JavaScript ArrayBuffer API: Reads binary files directly in memory PDF.js: Mozilla's JavaScript PDF library renders and manipulates PDFs pdf-lib: A pure JavaScript PDF library that creates, modifies, and merges PDFs File System Access API: Read/write files to your device from the browser
PDFBro uses these browser APIs to perform PDF operations in your browser tab — the same environment you use to watch videos and run web apps.
