  • the answer from softwarerecs.stackexchange.com/questions/74571/… or other questions with the tag of ocr may potentially be helpful Jan 17 at 20:57
  • This image isn't particularly ideal for OCR--looks cropped from a larger source and possibly reformatted. The background noise would also interfere with an OCR process. A commercial toolkit (such as LEADTOOLS -- note I work for this company) likely has image preprocessing sufficient to clean up the image to improve the OCR results. End-user solutions would likely automate this process. Apr 30 at 13:20

IronOcr specializes in reading even low quality images like this, even without the need for pre-processing, due to the in-built image optimization filters.

You can then export the result as a searchable PDF.

This is easily achievable in just a few lines of code:

var Ocr = new IronTesseract();
using (var Input = new OcrInput(@"images\image.png"))
{
Input.Deskew();
// Input.DeNoise(); // only use if accuracy <97%
var Result = Ocr.Read(Input);
Console.WriteLine(Result.Text);
}

Supports Tesseract OCR on Mac, Windows, Linux, Azure and Docker.
