iText is a popular Java library for creating and manipulating PDF documents. It's known for its wide range of features and its ability to handle complex PDF structures. However, there are times when you might need an alternative to iText, whether it's due to specific requirements, licensing concerns, or a preference for a different programming language.
Here are some compelling reasons why you might seek iText alternatives:
- Licensing: iText offers both free and commercial licenses. The free license comes with limitations, while the commercial license can be expensive for some projects.
- Language Support: iText is primarily a Java library, which may not be suitable for projects using other programming languages.
- Specific Features: iText might not have the specific features you require, such as advanced image processing, form manipulation, or support for certain PDF standards.
- Performance: While iText is generally efficient, performance can become a concern when working with very large or complex PDF documents.
Let's dive into some of the most prominent iText alternatives and explore their strengths:
