1. What is Tesseract OCR and Is It Free?

Tesseract OCR is an open-source OCR engine developed initially by HP and later maintained by Google. It supports over 100 languages and is widely used for text extraction from images, PDFs, and scanned documents.

Key Features:

Limitations:

Installation:

We have a detailed Post which allows you to install any version of Tesseract OCR, because some documentation was missing on official Page of Tesseract OCR.

2. Tesseract OCR vs Pytesseract

Pytesseract is a Python wrapper for Tesseract OCR, making it easier to use in Python applications. Tesseract is originally comes into c and c++ bindings which is easier to use using command line, however, in order to integrate it into your Python code we have python based wrapper (Pytesseract  or TesserOCR)
