A pure Ruby library for generating PDF documents with extensive text, vector drawing, and internationalization support.
Prawn is a pure Ruby library for generating PDF documents programmatically. It provides a wide range of features including vector drawing, text rendering with internationalization support, image embedding, and security options like encryption. It solves the need for a flexible, dependency-free PDF creation tool within the Ruby ecosystem.
Ruby developers who need to generate PDF documents directly from their applications, such as those building reporting tools, invoices, certificates, or custom document pipelines.
Developers choose Prawn for its pure Ruby implementation, extensive feature set, and low-level control over PDF generation without the overhead of external dependencies. It’s particularly valued for its internationalization support and flexibility in creating complex layouts.
Fast, Nimble PDF Writer for Ruby
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Has no external dependencies, making installation and deployment straightforward across all supported Ruby versions and JRuby, as emphasized in the README.
Supports vector drawing, multilingual text with UTF-8 and right-to-left rendering, image embedding, and security features like encryption, covering most PDF generation needs out of the box.
Provides access to the PDF object tree for custom extensions, allowing developers with PDF specification knowledge to fine-tune or extend functionality beyond the standard API.
Includes full UTF-8 support, fallback fonts, and customizable text wrapping, making it reliable for global applications with diverse language requirements.
Explicitly not an HTML-to-PDF converter; inline styling is very basic and unsuitable for rendering rich HTML documents, as admitted in the README.
Requires understanding of PDF concepts and Ruby coding for even basic layouts, making it less accessible for quick prototypes or developers unfamiliar with low-level document generation.
Release policies warn that experimental features may change, and bug fixes can alter behavior, necessitating careful testing and version locking, as noted in the CHANGELOG.
