Additional OCR Language Packs

Updated: August 2, 2026

IronOCR supports 125 international languages, but only English is installed within IronOCR as standard.

Additional Language packs may be easily added to your C#, VB or ASP .NET project via NuGet or as DLLs which can be downloaded and added as project references.

Code Examples

International Language Example

PM > Install-Package IronOcr.Languages.ChineseSimplified

Install-Package IronOcr.Languages.ChineseSimplified

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use Chinese Simplified
ocr.Language = OcrLanguage.ChineseSimplified;

using (var input = new OcrInput())
{
    // Add an image to be processed
    input.AddImage("img/chinese.gif");

    // Optional: Enhance the input by deskewing or denoising the image
    // input.Deskew();
    // input.DeNoise();

    // Process the image and retrieve the result
    var result = ocr.Read(input);

    // Store the recognized text in a string
    string testResult = result.Text;

    // Save the recognized text to a file since the console might not display Unicode characters properly
    result.SaveAsTextFile("chinese.txt");
}

Vertically Written Language Example

Dictionaries tuned for vertically written languages. Use 'Vertical' Variant of Korean and Japanese OcrLanguage.

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use Japanese Vertical language
ocr.Language = OcrLanguage.JapaneseVertical;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use Japanese Vertical language
ocr.Language = OcrLanguage.JapaneseVertical;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use Japanese Vertical language
ocr.Language = OcrLanguage.JapaneseVertical

Using input = New OcrInput("images\image.png")
	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use Japanese Vertical language

	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Custom Language Example

For using any Tesseract .traineddata language file you have downloaded or trained yourself.

using IronOcr;

var ocr = new IronTesseract();

// Use a custom Tesseract language file
ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

using IronOcr;

var ocr = new IronTesseract();

// Use a custom Tesseract language file
ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr = New IronTesseract()

' Use a custom Tesseract language file
ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata")

Using input = New OcrInput("images\image.png")
	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Imports IronOcr

Private ocr = New IronTesseract()

' Use a custom Tesseract language file
ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata")

Using input = New OcrInput("images\image.png")
	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Multiple Language Example

More than one language at a time.

PM > Install-Package IronOcr.Languages.Arabic

Install-Package IronOcr.Languages.Arabic

using IronOcr;

var ocr = new IronTesseract();

// Set the primary language to English
ocr.Language = OcrLanguage.English;
// Add Arabic as a secondary language
ocr.AddSecondaryLanguage(OcrLanguage.Arabic);
// Add any number of languages

using (var input = new OcrInput(@"images\multi-lang.pdf"))
{
    // Process the PDF and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

using IronOcr;

var ocr = new IronTesseract();

// Set the primary language to English
ocr.Language = OcrLanguage.English;
// Add Arabic as a secondary language
ocr.AddSecondaryLanguage(OcrLanguage.Arabic);
// Add any number of languages

using (var input = new OcrInput(@"images\multi-lang.pdf"))
{
    // Process the PDF and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console

	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Faster Language Example

Dictionaries tuned for speed. Use the 'Fast' variant of any OcrLanguage.

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use the fast variant of English
ocr.Language = OcrLanguage.EnglishFast;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use the fast variant of English
ocr.Language = OcrLanguage.EnglishFast;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use the fast variant of English
ocr.Language = OcrLanguage.EnglishFast

Using input = New OcrInput("images\image.png")
	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use the fast variant of English
ocr.Language = OcrLanguage.EnglishFast

	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Higher Accuracy Detail Language Example

Dictionaries tuned for accuracy, but much slower results. Use the 'Best' variant of any OcrLanguage.

PM > Install-Package IronOcr.Languages.French

Install-Package IronOcr.Languages.French

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use the best variant of French
ocr.Language = OcrLanguage.FrenchBest;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use the best variant of French
ocr.Language = OcrLanguage.FrenchBest;

using (var input = new OcrInput(@"images\image.png"))
{
    // Process the image and get the OCR result
    var result = ocr.Read(input);
    // Output the recognized text to the console
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use the best variant of French
ocr.Language = OcrLanguage.FrenchBest

Using input = New OcrInput("images\image.png")
	' Process the image and get the OCR result
	Dim result = ocr.Read(input)
	' Output the recognized text to the console
	Console.WriteLine(result.Text)
End Using

Imports IronOcr

Private ocr = New IronTesseract()
' Set the OCR to use the best variant of French
ocr.Language = OcrLanguage.FrenchBest

Using input = New OcrInput("images\image.png")
