  • Export OCR to searchable PDF documents
  • Multithreading support
  • 125 international languages all managed via Nuget or OcrData files
  • Extract Images, Coordinates, Statistics and Fonts. Not just text.
  • Can be used to redistribute Tesseract OCR inside commercial & proprietary applications.
  • Supports: windows Linux Mac Azure AWS Docker

IronOCR shines when working with real world images and imperfect documents such as photographs, or scans of low resolution which may have digital noise or imperfections. Other free OCR libraries for the .NET platform such other .Net Tesseract APIs and web services do not perform so well on these real world use cases.  

OCR with Tesseract 5 - Start Coding in C#

These code examples below shows how easy it is to read text from an image using C# or VB .NET.

Configurable Hello World

using IronOcr;

var Ocr = new IronTesseract();
using (var Input = new OcrInput()){
    Input.AddImage("images/sample.jpeg")
    //... you can add any number of images
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

 

C# PDF OCR

The same approach can similarly be used to extract text from any PDF document.

var Ocr = new IronTesseract();
using (var input = new OcrInput())
{

    input.AddPdf("example.pdf","password");
    // We can also select specific PDF page numnbers to OCR
        
    var Result = Ocr.Read(input);

    Console.WriteLine(Result.Text);
    Console.WriteLine($"{Result.Pages.Count()} Pages");
    // 1 page for every page of the PDF
}
