In this article, we are going to compare two of the most common libraries and applications for OCR raster formats and PDF document images. These are:

Aspose.OCR
IronOCR

1.0 Introduction

1.1 Aspose.OCR Introduction and Features

Aspose.OCR for .NET is a powerful and robust package for Optical Character Recognition. This is an excellent addition to any application and can automate the process. The standalone OCR API is extensible, user-friendly, and compact. It comes with a simple set of classes that provide all the functionality you need to get started recognizing text without any additional hassle and maintain correct text order. Aspose.OCR can read over 100 different formats and provides a myriad of useful functions, ranging from the ability to read fonts, apply style effects (bold/italic), and even remove noise from your image. The API can use the GPU to perform Optical Character Recognition and save power on your CPU.

Features of Aspose.OCR

Programmatically detect, identify, and read characters from images.
Scan the whole image or only a specific portion of the image.
Skew correction for OCR operation; scan rotated images.
Supports JPEG, PNG, GIF, etc. For the complete list of supported file formats, please visit the Supported File Formats page and subscribe to the Aspose product.
Support for many characters, including numbers and alphabets. For the complete list of supported characters, please visit the Supported Characters page.
Supports 130+ languages based on Latin, Cyrillic, Chinese, Arabic, Korean, Japanese, Devanagari, and Indic scripts (as of 2025).
Detect and read popular font faces such as Arial, Times New Roman, Courier New, Tahoma, Calibri, and Verdana.
Supports regular, bold, and italic font styles.
Application of various noise removal filters to assist image recognition.

4.0 OCR Image

Both IronOCR and Aspose.OCR have an OCR technology that will convert images into text.

4.1 Using Aspose.OCR

The following code snippet demonstrates the use of the RecognizeImage method to perform an OCR operation on the image of a page.

// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_OCR();
// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();
// Recognize image
string result = api.RecognizeImage(dataDir + "Sampleocr.bmp");
// Display the recognized text
Console.WriteLine(result);

// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_OCR();
// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();
// Recognize image
string result = api.RecognizeImage(dataDir + "Sampleocr.bmp");
// Display the recognized text
Console.WriteLine(result);

' For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
' The path to the documents directory.
Dim dataDir As String = RunExamples.GetDataDir_OCR()
' Initialize an instance of AsposeOcr
Dim api As New AsposeOcr()
' Recognize image
Dim result As String = api.RecognizeImage(dataDir & "Sampleocr.bmp")
' Display the recognized text
Console.WriteLine(result)

$vbLabelText $csharpLabel

The following code snippet demonstrates the use of the RecognizeLine method to perform an OCR operation on an image containing a single line.

// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_OCR();

// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();

// Recognize image
string result = api.RecognizeLine(dataDir + "sample_line.png");

// Display the recognized text
Console.WriteLine(result);

// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_OCR();

// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();

// Recognize image
string result = api.RecognizeLine(dataDir + "sample_line.png");

// Display the recognized text
Console.WriteLine(result);

' For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-.NET
' The path to the documents directory.
Dim dataDir As String = RunExamples.GetDataDir_OCR()

' Initialize an instance of AsposeOcr
Dim api As New AsposeOcr()

' Recognize image
Dim result As String = api.RecognizeLine(dataDir & "sample_line.png")

' Display the recognized text
Console.WriteLine(result)

$vbLabelText $csharpLabel

4.2 Using IronOCR

var Ocr = new IronTesseract(); // nothing to configure
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;
using (var Input = new OcrInput())
{
    Input.AddImage(@"3.png");
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    Console.ReadKey();
}

var Ocr = new IronTesseract(); // nothing to configure
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;
using (var Input = new OcrInput())
{
    Input.AddImage(@"3.png");
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    Console.ReadKey();
}

Dim Ocr = New IronTesseract() ' nothing to configure
Ocr.Language = OcrLanguage.EnglishBest
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5
Using Input = New OcrInput()
	Input.AddImage("3.png")
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
	Console.ReadKey()
End Using

$vbLabelText $csharpLabel

The Tesseract 5 API, which allows us to convert image files into text, is demonstrated above. We're making an object for IronTesseract in the above line of code. We're also making an OcrInput object that will allow us to add one or more picture files. We may need to give the available picture path inside the code when utilizing the OcrInput object method add. Any number of images can be added. The function Read in the IronTesseract object that we constructed before may be utilized to get the images by parsing the image file and extracting the result into the OCR result. It is capable of extracting text from photos and converting it to a string.

We can also use Tesseract to add multi-frame images. AddMultiFrameTiff is a different method for this operation. The Tesseract library reads each frame in the image, and each frame is treated as a distinct page. The process will read the first frame of the image and then proceed on to the next frame, and so on until all of the image's frames have been scanned. Only the TIFF image format is supported by this method.

IronOCR Installation

The above image is the output of the IronOCR result which has accurately converted the data into editable text.

5.0 OCR PDF Files

IronOCR and Aspose.OCR convert PDF files into editable text. Aspose.OCR provides a list of options to the user such as save the page, edit the image, recognizing the page, etc. It also provides save options such as text, document, HTML format, etc. IronOCR also allows us to save a converted OCR file into HTML, text, PDF, etc.

5.1 Using Aspose.OCR

Aspose.OCR provides the RecognizePdf method that can recognize text in the images extracted from scanned PDF files. The RecognizePdf method takes the PDF path as a parameter and the DocumentRecognitionSettings object. The following code snippet demonstrates the use of the RecognizePdf method to recognize images from a scanned multipage PDF file.

// The path to the PDF file
string dataDir = RunExamples.GetDataDir_OCR();
// Archive Path
string fullPath = dataDir + "OCR.pdf";
// Recognize images from PDF           
DocumentRecognitionSettings set = new DocumentRecognitionSettings();
set.DetectAreas = false;
List<RecognitionResult> result = api.RecognizePdf(fullPath, set);
// Print result
int pageNumber = 0;
foreach (var page in result)
{                
    System.Console.WriteLine($"Page: {pageNumber++} text: {page.RecognitionText}");
}

// The path to the PDF file
string dataDir = RunExamples.GetDataDir_OCR();
// Archive Path
string fullPath = dataDir + "OCR.pdf";
// Recognize images from PDF           
DocumentRecognitionSettings set = new DocumentRecognitionSettings();
set.DetectAreas = false;
List<RecognitionResult> result = api.RecognizePdf(fullPath, set);
// Print result
int pageNumber = 0;
foreach (var page in result)
{                
    System.Console.WriteLine($"Page: {pageNumber++} text: {page.RecognitionText}");
}

' The path to the PDF file
Dim dataDir As String = RunExamples.GetDataDir_OCR()
' Archive Path
Dim fullPath As String = dataDir & "OCR.pdf"
' Recognize images from PDF           
Dim [set] As New DocumentRecognitionSettings()
[set].DetectAreas = False
Dim result As List(Of RecognitionResult) = api.RecognizePdf(fullPath, [set])
' Print result
Dim pageNumber As Integer = 0
For Each page In result
'INSTANT VB WARNING: An assignment within expression was extracted from the following statement:
'ORIGINAL LINE: System.Console.WriteLine(string.Format("Page: {0} text: {1}", pageNumber++, page.RecognitionText));
	System.Console.WriteLine($"Page: {pageNumber} text: {page.RecognitionText}")
	pageNumber += 1
Next page

$vbLabelText $csharpLabel

5.2 Using IronOCR

We can also use OCRInput to manage PDF files. Every page of a document will be read by the IronTesseract class. The text will then be extracted from the pages. We may also open protected documents using a second function called AddPDF, which allows us to add PDFs to our list of documents (password if it is protected). The following code demonstrates how to open a password-protected PDF document:

var Ocr = new IronTesseract(); // nothing to configure
using (var Input = new OcrInput())
{
    Input.AddPdf("example.pdf", "password");
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

var Ocr = new IronTesseract(); // nothing to configure
using (var Input = new OcrInput())
{
    Input.AddPdf("example.pdf", "password");
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

Dim Ocr = New IronTesseract() ' nothing to configure
Using Input = New OcrInput()
	Input.AddPdf("example.pdf", "password")
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
End Using

$vbLabelText $csharpLabel

We can read and extract content from a single page in a PDF document using AddPdfPage. Only the page number from which we want to extract text needs to be specified. AddPdfPage allows us to extract text from numerous pages that we specify. In IEnumerable<int>, we can easily specify multiple pages. We must also include the file location as well as the extension of the file. This is demonstrated in the following code example:

IEnumerable<int> numbers = new List<int> {2, 8, 10};
var Ocr = new IronTesseract();
using (var Input = new OcrInput())
{
    // Single page
    Input.AddPdfPage("example.pdf", 10);
    // Multiple pages
    Input.AddPdfPages("example.pdf", numbers);
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    Result.SaveAsTextFile("ocrtext.txt");
}

IEnumerable<int> numbers = new List<int> {2, 8, 10};
var Ocr = new IronTesseract();
using (var Input = new OcrInput())
{
    // Single page
    Input.AddPdfPage("example.pdf", 10);
    // Multiple pages
    Input.AddPdfPages("example.pdf", numbers);
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    Result.SaveAsTextFile("ocrtext.txt");
}

Dim numbers As IEnumerable(Of Integer) = New List(Of Integer) From {2, 8, 10}
Dim Ocr = New IronTesseract()
Using Input = New OcrInput()
	' Single page
	Input.AddPdfPage("example.pdf", 10)
	' Multiple pages
	Input.AddPdfPages("example.pdf", numbers)
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
	Result.SaveAsTextFile("ocrtext.txt")
End Using

$vbLabelText $csharpLabel

Using the SaveAsTextFile function, we can store the result as a text file, which allows us to download the file to the output directory path. Also, we can save the file into an HTML file using SaveAsHocrFile.

6.0 Other Features

6.1 Using Aspose.OCR

Aspose.OCR has some additional options such as Draw Text Area, Draw Picture Area, Draw Table Area, Draw Recognize Area, etc. These all help the user to improve the performance of the OCR. Not only does the application perform OCR, but we are also able to perform operations such as combine PDFs, split PDFs, edit PDFs, etc.

6.2 Using IronOCR

IronOCR has unique features which allow us to read barcodes and QR codes from scanned documents. The below code shows how we can read a barcode from a given image or document.

var Ocr = new IronTesseract(); // nothing to configure
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.ReadBarCodes = true;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;
using (var Input = new OcrInput())
{
    Input.AddImage("barcode.gif");
    var Result = Ocr.Read(Input);

    foreach (var Barcode in Result.Barcodes)
    {
        Console.WriteLine(Barcode.Value);
    }
}

var Ocr = new IronTesseract(); // nothing to configure
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.ReadBarCodes = true;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;
using (var Input = new OcrInput())
{
    Input.AddImage("barcode.gif");
    var Result = Ocr.Read(Input);

    foreach (var Barcode in Result.Barcodes)
    {
        Console.WriteLine(Barcode.Value);
    }
}

Dim Ocr = New IronTesseract() ' nothing to configure
Ocr.Language = OcrLanguage.EnglishBest
Ocr.Configuration.ReadBarCodes = True
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5
Using Input = New OcrInput()
	Input.AddImage("barcode.gif")
	Dim Result = Ocr.Read(Input)

	For Each Barcode In Result.Barcodes
		Console.WriteLine(Barcode.Value)
	Next Barcode
End Using

$vbLabelText $csharpLabel

The above is the code that helps to read a barcode from a given image or PDF document. It can read more than one barcode from the page/image. To read the barcode, IronOCR has a unique setting, Ocr.Configuration.ReadBarCodes. The default value is set to false.

After reading the input, the data will be saved into the object called OCRResult. This has a property called Barcodes, and it will have all the available barcode data in a list. By using the foreach loop, we can get all the barcode details one by one. Also, it will scan the barcode and read the value of the barcode — two operations completed in one process.

It supports threading options. We can perform multiple OCR processes at one time. IronOCR is also able to recognize a specific area from a specified region.

var Ocr = new IronTesseract();
using (var Input = new OcrInput())
{
    var ContentArea = new System.Drawing.Rectangle() { X = 215, Y = 1250, Height = 280, Width = 1335 };
    Input.Add("document.png", ContentArea);
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

var Ocr = new IronTesseract();
using (var Input = new OcrInput())
{
    var ContentArea = new System.Drawing.Rectangle() { X = 215, Y = 1250, Height = 280, Width = 1335 };
    Input.Add("document.png", ContentArea);
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

Dim Ocr = New IronTesseract()
Using Input = New OcrInput()
	Dim ContentArea = New System.Drawing.Rectangle() With {
		.X = 215,
		.Y = 1250,
		.Height = 280,
		.Width = 1335
	}
	Input.Add("document.png", ContentArea)
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
End Using

$vbLabelText $csharpLabel

The above is the sample code to perform OCR on a specific region. We only need to specify the rectangular region in the image or PDF. The Tesseract engine in IronOCR helps us to recognize the text.
