Let's start with how to use the IronPDF library to convert a PDF document to a Text file.

Steps to Convert PDF Document to Text File

The first step is to create a C# project in Visual Studio. You can choose any C# Application template according to your needs. For simplicity purposes, this tutorial will use the Console Application template. You can use an already existing C# project for converting PDF to TXT files.

Step 1: Create a C# Project

Create a C# project in Visual Studio or open an existing project. The latest version of Visual Studio is recommended for smooth working. Follow the given steps to create a C# Project in Visual Studio.

1. Open Visual Studio.
2. Select C# Console Application template or open an existing project.
3. Give a proper name to the project.
4. Select the .NET Framework version 6.0. This is the latest and most stable framework of .NET, but you can choose any other .NET Framework according to your needs.

Step 2: Install the IronPDF Library

IronPDF also features an easy installation process which speeds up development time as well as reduces confusion. The IronPDF library offers multiple ways to install:

Installation for the IronPDF library is now complete. The following steps will guide you to convert a PDF file into a text file.

Step 3: Add the IronPDF Namespace

To use IronPDF, it is necessary to add the IronPDF namespace to every code file. Write the following line of code at the top of every related code file. It will enable you to use the features of IronPDF in your program.

using IronPdf;

using IronPdf;

Imports IronPdf

Step 4: Convert the PDF Document to a Text file

Now we have to convert the PDF file to a TXT file or extract only text. So, write the following sample code into your code file:

using IronPdf;
using System;

class Program
{
    static void Main()
    {
        // Extracting image and text content from PDF Document

        // Open a 128-bit encrypted PDF
        using PdfDocument pdf = PdfDocument.FromFile("encrypted.pdf", "password");

        // Get all text to put in a search index
        string allText = pdf.ExtractAllText();

        // Display the extracted text in the console
        Console.WriteLine(allText);
    }
}

using IronPdf;
using System;

class Program
{
    static void Main()
    {
        // Extracting image and text content from PDF Document

        // Open a 128-bit encrypted PDF
        using PdfDocument pdf = PdfDocument.FromFile("encrypted.pdf", "password");

        // Get all text to put in a search index
        string allText = pdf.ExtractAllText();

        // Display the extracted text in the console
        Console.WriteLine(allText);
    }
}

Imports IronPdf

Imports System



Friend Class Program

	Shared Sub Main()

		' Extracting image and text content from PDF Document



		' Open a 128-bit encrypted PDF

		Using pdf As PdfDocument = PdfDocument.FromFile("encrypted.pdf", "password")

	

			' Get all text to put in a search index

			Dim allText As String = pdf.ExtractAllText()

	

			' Display the extracted text in the console

			Console.WriteLine(allText)

		End Using

	End Sub

End Class

First, open the PDF document using the FromFile function from the PdfDocument class. In the parameters, pass the file name and password (if any). After that, use the ExtractAllText function to extract all text from the PDF file and store it in a variable named allText. Following that, display the output text in the console.

Output

The extracted text from the PDF document

This is the output text extracted by the IronPDF. It is the same text as seen on the PDF file, showcasing that the accuracy of IronPDF is very precise.
