IronPDF is a .NET library for PDF generation. It is a native .NET library and does not rely on external DLL or other tools. IronPDF is a cross-platform library written in C# and .NET that offers all the functionality required to work with PDF documents. It contains document rendering, form editing, text extraction, file encryption as well as other features. All of these operations can be performed through an intuitive API that has been extensively tested on various platforms such as Windows Forms, WPF, ASP.NET MVC, etc.

The current release of IronPDF provides simple access to these features:

IronPDF also contains some additional helper classes that help with converting HTML documents into fully formatted PDF files with text extraction. IronPDF provides very simple APIs to convert PDF to a text file.

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:

  • Using NuGet Package Manager

Method 3: Using a DLL file

You can download the DLL file from the Iron Software website. Once the download is complete, use it in your project as a reference.

Visit the installation page for a more detailed installation guide.

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
VB   C#

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.Drawing;

// 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();
Console.WriteLine(allText);
using IronPdf;
using System.Drawing;

// 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();
Console.WriteLine(allText);
Imports IronPdf
Imports System.Drawing

' Extracting image and text content from PDF Document

' Open a 128-bit encrypted PDF
Private PdfDocument As using
' Get all text to put in a search index
Private allText As String = pdf.ExtractAllText()
Console.WriteLine(allText)
VB   C#

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
