How do I extract text from JPG and PNG files with OCR?

You can extract text from JPG and PNG images using OCR (Optical Character Recognition).

Common ways to do it

1) Python with Tesseract

Install:

pip install pytesseract pillow

You also need the Tesseract OCR engine installed on your system:

• Windows: install from the Tesseract installer
• macOS: brew install tesseract
• Ubuntu/Debian: sudo apt install tesseract-ocr

Example:

from PIL import Image
import pytesseract

img = Image.open("image.jpg")
text = pytesseract.image_to_string(img)
print(text)

For PNG, use the same code:

img = Image.open("image.png")
text = pytesseract.image_to_string(img)
print(text)

2) Python with OpenCV + Tesseract

Useful if you want to preprocess the image first for better accuracy.

pip install opencv-python pytesseract

Example:

import cv2
import pytesseract

img = cv2.imread("image.jpg")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
text = pytesseract.image_to_string(gray)
print(text)

3) Online OCR tools

If you don’t want to code, you can use web tools like:

• Google Drive OCR
• Adobe Acrobat online OCR
• OnlineOCR.net

---

4) Cloud OCR APIs

For higher accuracy and production use:

• Google Cloud Vision
• AWS Textract
• Azure Computer Vision

---

Tips for better OCR accuracy

• Use clear, high-resolution images
• Crop to the text region
• Convert to grayscale
• Improve contrast
• Remove noise
• Rotate/deskew if needed

Example preprocessing:

import cv2
import pytesseract

img = cv2.imread("image.png")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
thresh = cv2.threshold(gray, 150, 255, cv2.THRESH_BINARY)[1]
text = pytesseract.image_to_string(thresh)
print(text)
