    Unless you're processing images that have original text embedded (say, PS/AI/CDX/etc.), you'll need to employ some OCR technologies to deduce what are the text on the image.

    If you're developing for UWP, you may also consider classes from the Windows.Media.Ocr namespace.

    In general (Like cheong00 mentioned), the source files could either contain text or contain images of text. There is a solution that can handle both types of source files, which is the LEADTOOLS Document Converter SDK Libraries. (Disclaimer: I am a LEADTOOLS employee).

    The following code converts many types of input files and images to text, and automatically invoked OCR if needed:

    private void ConvertToText(string inputFileName)
    {
       var options = new LoadDocumentOptions();
       using (var document = DocumentFactory.LoadFromFile(inputFileName, options))
       {
          using (DocumentConverter documentConverter = new DocumentConverter())
          {
             Leadtools.Ocr.IOcrEngine ocrEngine = Leadtools.Ocr.OcrEngineManager.CreateEngine(Leadtools.Ocr.OcrEngineType.LEAD);
             ocrEngine.Startup(null, null, null, ocrEnginePath);
             documentConverter.SetOcrEngineInstance(ocrEngine, false);
             var outFile = inputFileName + "_converted.txt";
             var format = Leadtools.Document.Writer.DocumentFormat.Text;
             var jobData = DocumentConverterJobs.CreateJobData(document, outFile, format);
             jobData.JobName = "conversion job";
             var job = documentConverter.Jobs.CreateJob(jobData);
             documentConverter.Jobs.RunJob(job);
             MessageBox.Show(job.Errors.Count.ToString() + " " + outFile);
          }
       }
    }
