mPDF is a PHP library that enables the creation of PDF documents from UTF-8 encoded HTML. It builds on the legacy of FPDF and HTML2FPDF while adding several enhancements. Although it is generally slower than earlier versions like HTML2FPDF and tends to produce larger files when working with Unicode fonts, it provides features such as CSS styling and various other improvements. Despite these strengths, mPDF is often seen as somewhat outdated, especially with the emergence of more sophisticated alternatives that are not reliant on PHP. If your project restricts you to using PHP for PDF creation or if you want to take advantage of mPDF's distinct features, including color management, barcode support, and the ability to customize headers and footers, it can still be a practical choice. However, it is crucial to design an HTML/CSS template tailored specifically for mPDF to achieve the best possible outcomes. For enhanced CSS support and the capability to accurately reproduce existing HTML pages in a PDF format, employing headless Chrome is highly recommended. Furthermore, mPDF is likely to keep receiving updates aimed at enhancing its internal mechanisms and ensuring compatibility with newer versions of PHP, which will help it remain a pertinent option for developers moving forward. As the landscape of PDF generation technologies evolves, mPDF may adapt to incorporate modern features that align with current development practices.
