No longer will you need to engage in the cumbersome chore of manual coordinate adjustments; instead, you can sketch out your document's layout and allow pdfmake to manage the detailed aspects. The library accommodates a variety of components such as paragraphs, columns, lists, tables, and canvas, providing extensive design freedom. You have the ability to establish your own styles, use custom fonts, develop a domain-specific language (DSL), and tailor the framework to fit your specific requirements. Notable features include line wrapping, multiple text alignments (left, right, center, justified), and support for both numbered and bulleted lists, along with customizable margins, images, and vector graphics. Furthermore, the library provides user-friendly styling options, style inheritance, and the capability to create custom style dictionaries. You can also define column widths as auto, fixed, star-sized, or percentage-based, manage colspans and rowspans effectively, and ensure that headers are automatically repeated during page breaks. It preserves the integrity of your layout by utilizing non-breaking rows and sections, which maintain alignment between headers and content, accommodating both static and dynamic data. Additionally, the framework includes features for page numbers and total page counts, enhancing the polished look of the final document. Overall, pdfmake not only simplifies the PDF creation process but also equips users with the tools necessary to produce high-quality documents with ease, making it an invaluable resource for developers.

Dompdf operates as a powerful tool that converts HTML documents into PDF files. At its foundation, it acts as a PHP-based layout and rendering engine that primarily adheres to the CSS 2.1 specification. This renderer, driven by styling, can download and process external stylesheets while also managing inline style tags and specific HTML element attributes. Furthermore, it recognizes a wide array of presentational HTML attributes, enhancing its usability. For PDF generation, dompdf relies on either PDFLib or a tailored version of the R&OS CPDF class, initially developed by Wayne Munro, with various improvements incorporated to bolster performance. To effectively use PDFLib with dompdf, the installation of the PDFLib PECL extension is necessary. While PDFLib integration can optimize performance and reduce memory usage, the R&OS CPDF class, although slightly slower, eliminates the requirement for any external PDF libraries. Dompdf is proficient in supporting both local and remote stylesheets that can be accessed through HTTP or FTP protocols. Additionally, it can manage complex table structures, allowing for features like row and column spans, multiple border models, and individual cell styling options. This extensive functionality positions dompdf as a highly adaptable and effective solution for generating PDFs from HTML content, making it an excellent option for developers looking to create well-styled documents.

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.
