What is OCR and what is it used for?

Optical Character Recognition extracts machine-readable text from images. Typical uses are scanning invoices to pull out payment details, parsing printed receipts for inventory applications, and reading license plates — anywhere text exists only as pixels and needs to become data.

Should you use Tesseract or EasyOCR in Python?

pytesseract wraps Google's Tesseract engine and suits straightforward printed text. EasyOCR is built on deep learning with strong multilingual support. Both install together with pip install pytesseract easyocr pillow, so trying each against your actual documents is usually faster than choosing in advance.

How do you extract text from an image in Python?

With Tesseract it is two lines: open the image with PIL and call pytesseract.imagetostring on it. EasyOCR uses a Reader initialised with the languages you expect, then readtext returns each detected region, so you iterate over results rather than receiving one block of text.

Can OCR handle more than one language at a time?

Yes, and both libraries support it directly. Tesseract takes a combined language string such as lang='eng+hin', while EasyOCR takes a list when the reader is created, for example Reader(['en', 'hi', 'fr']). Declaring the expected languages up front improves accuracy on mixed documents.

Looking for a way to turn photos or scanned documents into real, editable text? Welcome to the world of OCR — Optical Character Recognition.

What is OCR?

OCR helps you extract machine-readable text from images. From scanning invoices to digitizing receipts or reading license plates — it automates it all.

Best Python Libraries for OCR

pytesseract – A Python wrapper for Google’s Tesseract engine.
EasyOCR – Built for deep learning-based OCR with multilingual capabilities.

How to Set Up OCR in Python

Install dependencies:

pip install pytesseract easyocr pillow

Code Example – Extracting Text from an Invoice

Using Tesseract:

`from PIL import Image import pytesseract

text = pytesseract.imagetostring(Image.open('invoice.png')) print(text) `

Using EasyOCR:

`import easyocr

reader = easyocr.Reader(['en']) results = reader.readtext('receipt.jpg') for result in results: print(result[1]) `

Detect Multilingual Text

Both tools support multiple languages.

pytesseract : Use lang='eng+hin'

easyocr : Use Reader(['en', 'hi', 'fr'])

Use Cases

Scan invoices and extract payment details
Parse printed receipts for inventory apps
Read license plates from traffic cams
Translate text from foreign signage
