It's called optical character recognition, or OCR. Google and find a library that fits your needs and programming skills. You will not be able to write something like this by yourself.

Hi jsshivalik,
As ryanbesko mentioned, some text recognition APIs or OCR services can help recognize and extract text, such as Azure's Computer Vision service.
https://docs.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-recognizing-text#ocr-optical-character-recognition-api
Note: Azure's Computer Vision service OCR API currently works on images only, not support PDF file.
