## Extract Text Using IronPDF 

With IronPDF, you can easily extract text from any PDF document using a variety of methods tailored to different needs. This section will guide you through the process of installing IronPDF, loading a PDF document, and extracting text using various techniques.

IronPDF offers robust functionality that simplifies the extraction process, whether you need to retrieve all text, text from specific pages, or text line by line. This flexibility ensures that you can handle various PDF text extraction scenarios efficiently. Let’s explore how to set up IronPDF and use its features to extract text from your PDF documents.

### Step 1:  Install IronPDF Library

To start using IronPDF in your C# project, you need to install the library via NuGet Package Manager. Open your project in Visual Studio, then follow these steps:

1. Right-click on your project in the Solution Explorer.
2. Select “Manage NuGet Packages...”
3. Search for “IronPDF” in the Browse tab.
4. Click “Install” to add the IronPDF library to your project.

You can also use NuGet Package manager console for installing IronPDF library using command line:

```
Install-Package IronPdf
```

Once installed, you will have access to the various features IronPDF offers, including PDF creation, editing, and text extraction. Ensure that you have the appropriate directives in your code to utilize IronPDF functionalities:

```
using IronPdf;
```

This setup will enable you to efficiently work with PDF documents in your C# applications.

### Step 2: Load the PDF Document

Before extracting text, you need to load the PDF file into your application. IronPDF makes this process straightforward. Here’s a sample code snippet to load a PDF format:

```
// Load the PDF document
var pdf = PdfDocument.FromFile("path/to/your/document.pdf");
```
The above code loads the PDF file. Loading the document is the first step towards interacting with its content.

### Step 3: Extract Text from PDF

IronPDF provides several methods to extract PDF text, allowing you to choose the one that best fits your needs.

#### Extract All Text

To extract all the text from a PDF document, you can use the ExtractAllText method. This method returns the entire text content of the PDF as a single string.

```
// Extract all text from the PDF
var text = pdf.ExtractAllText();

//Show Extracted text on console
Console.WriteLine(allText);
```

Extracting all text at once is useful for situations where you need a complete snapshot of the document’s textual content. This method is straightforward and can be used to pull all the text for further processing or analysis quickly.

#### Extract Text from Specific Pages

If you need to extract text from specific pages, you can specify the page numbers. The following example demonstrates how to extract text from the first page of the PDF:

```
// Extract text from specific pages
string text = pdf.ExtractTextFromPage(1);
Console.WriteLine(text);

int[] pages = new[] { 0, 1 };
// Extract text from pages 1 & 2
string pages2 = pdf.ExtractTextFromPages(pages);
Console.WriteLine(pages2);
```

This approach is beneficial when you are only interested in certain sections of a document, such as specific chapters in a book or particular sections in a report.

#### Extract Text Line by Line

Extracting text line by line can be useful for more granular text processing. IronPDF provides a method to extract text line by line, ensuring you can process each line individually.

```
// Extract text by lines
var lines = pdf.Pages[1].Lines;
```

Line-by-line extraction is particularly useful for scenarios where you need to process or analyze text in smaller chunks, such as parsing through each sentence or dealing with formatted data. This method allows for detailed text manipulation, making it easier to handle tasks like data extraction and content analysis.

By using these methods, you can efficiently extract and manipulate text from your PDF documents in various ways, depending on your requirements. IronPDF’s flexibility and ease of use make it an excellent choice for handling PDF text extraction in your C# applications.
