iText Core/Community is a high-performance, battle-tested library that allows you to create, adapt,
inspect and maintain PDF documents, allowing you to add PDF
functionality to your software projects with ease. It is also available for .[NET][itext7net] (C#).

### The key features of iText Core/Community are:

* Core library:
 * PDF creation with the use of our layout engine
 * PDF manipulation, e.g. merging multiple PDFs into one, adding new content, ...
 * PDF digital signing 
 * PDF form creation and manipulation
 * Working with PDF/A documents
 * Working with PDF/UA documents
 * FIPS-compliant cryptography
 * Barcode generation
 * SVG support
* [Addons:][all products]
 * Converting XML/HTML & CSS to PDF [repo][pdfhtml], [info][pdfhtmlproduct]
 * Redacting sensitive information in PDF documents [repo][pdfsweep], [info][pdfsweepproduct]
 * Support for international character sets (e.g. Arabic, Chinese, Hebrew, Thai, ...) [info][calligraph]
 * Optimize PDF documents for reduced file size, and increased performance [info][optimizer]
 * Flattening XFA documents [info][xfa]
 * PDF debugging [repo][rups], [info][rupsproduct]

Want to discover what's possible? Head over to our [Demo Lab](https://itextpdf.com/demos)! It contains a collection of
demo applications ready to use online!

### Getting started

The easiest way to get started is to use Maven, just add the following entries to your pom.xml file:

```html

<properties>
 <itext.version>8.0.2</itext.version>
</properties>
<dependencies>
 <dependency>
 <groupId>com.itextpdf</groupId>
 <artifactId>itext-core</artifactId>
 <version>${itext.version}</version>
 <type>pom</type>
 </dependency>
 <dependency>
 <groupId>com.itextpdf</groupId>
 <artifactId>bouncy-castle-adapter</artifactId>
 <version>${itext.version}</version>
 </dependency>
</dependencies>
```

For more advanced use cases, please refer to
the [Installation guidelines](https://kb.itextpdf.com/home/it7kb/installation-guidelines).
You can also [build iText Community from source][building].

### Hello PDF!

The following example shows how easy it is to create a simple PDF document:

```java
package com.itextpdf.hellopdf;

import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.layout.Document;
import com.itextpdf.layout.element.Paragraph;

import java.io.FileNotFoundException;

public class HelloPdfApp {

public static void main(String[] args) throws FileNotFoundException {
 try (Document document = new Document(new PdfDocument(new PdfWriter("./hello-pdf.pdf")))) {
 document.add(new Paragraph("Hello PDF!"));
 }
 }
}
```

### Examples

This is a small subset of examples to get you started. For more advanced examples, refer to our [Knowledge Base](https://kb.itextpdf.com/home/it7kb/examples) or the following links:
[Examples repo](https://github.com/itext/i7js-examples), [Signing examples](https://github.com/itext/i7js-signing-examples).

Some of the output PDF files will be incorrectly displayed by the GitHub previewer, so be sure to download them to see the correct
results.
