PoDoFo is a free and open-source C++ library for working with the PDF file format. It provides functionality for creating, modifying, and parsing PDF documents programmatically. The library is designed to be cross-platform and is commonly used in applications that require low-level access to PDF structure and content.
History
PoDoFo was first released in June 2006 by Dominik Seichter, who also maintained the library with contributions from volunteers. The library has since been widely packaged in various Linux distributions and software repositories, often accompanied by a set of command-line tools for PDF processing.[1]
In 2023, maintainership transitioned to Francesco Pretto. Subsequent development introduced extensive changes to the library, including significant API revisions, adoption of modern C++ standards, improvements to PDF standards support and expanded signing capabilities, and numerous fixes and improvements across the codebase.
In 2025, the PoDoFo community became a member of the PDF Association, an international organization promoting open standards for PDF technology.[2] The library is also listed as a PDF-related product by the PDF Association.[3]
Features
PoDoFo provides a range of features for PDF manipulation, including:
- Parsing PDF files with access to structured elements such as annotations and form fields
- Writing and updating PDF documents, including incremental modifications without rewriting entire files
- Extraction of text content from PDF documents with Unicode support
- Text drawing with automatic encoding generation and font embedding/subsetting
- Support for digital signatures, including standards such as PAdES
- Support for East Asian (CJK) languages in both text extraction and text filling
- Preservation of compliance with standards such as PDF/A and PDF/UA when modifying documents
The library exposes relatively low-level access to PDF internals compared to higher-level PDF frameworks, allowing fine-grained control over document structure.
Architecture
PoDoFo is implemented in C++ and follows a modular design centered around core PDF concepts such as objects, dictionaries, streams, and cross-reference tables. It provides both high-level convenience APIs and lower-level primitives for direct manipulation of PDF elements.
The project uses modern C++ standards in recent versions and supports common build systems such as CMake.
Development
The source code is hosted on GitHub, where development is conducted openly. The project includes a test suite and documentation aimed at developers integrating the library into their applications.
Recent development efforts have focused on improving code quality, expanding compatibility with newer PDF specifications, and modernizing the API.
Licensing
PoDoFo is distributed under a dual license: the GNU Lesser General Public License (LGPL) version 2.0 or later, and the Mozilla Public License (MPL) version 2.0. This allows its use in both open-source and proprietary software under certain conditions.
