Mohamed Abedallah · Answer

You may try LEADTOOLS OCR SDK. With LEADTOOLS you can recognize PDF files and also you can save the result as searchable PDF. The code is as simple as this: using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false )) { ocrEngine.Startup( null , null , null , null ); string InputFileName = @ "C:	emp\Input.pdf" ; string OutputFileName = @ "C:	emp\Output.pdf" ; using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument()) { IOcrPage ocrPage = ocrDocument.Pages.AddPage(InputFileName, null ); ocrPage.AutoZone( null ); ocrPage.Recognize( null ); ocrDocument.Save(OutputFileName, DocumentFormat.Pdf, null ); } ocrEngine.Shutdown(); } For more information, see the following link: https://www.leadtools.com/help/leadtools/v20/dh/to/ocr.html You can also test the online demo here: http://demo.leadtools.com/JavaScript/OCR/index.html
