With LEADTOOLS OCR features you can recognize text from almost all common image formats along with PDF files. You can achieve that using LEADTOOLS with .NET code similar to this: IOcrEngine _ocrEngine; _ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage false ); _ocrEngine.Startup( null  null  null  null ); IOcrDocument ocrDoc = _ocrEngine.DocumentManager.CreateDocument(); ocrDoc.Pages.AddPage(inputFileName null ); ocrDoc.Pages[0].Recognize( null ); // Save the result to a disk as plain text string outputFileName = output.txt ; ocrDoc.Save(outputFileName Leadtools.Forms.DocumentWriters.DocumentFormat.Text null ); _ocrEngine.Shutdown(); To see how it works check this link: http://demo.leadtools.com/JavaScript/OCR/index.html
