Converting Image to Text by Converting to PDF

Converting images to PDF is a straightforward way to extract text without needing complex software. Follow these five easy steps:

  1. Choose an Image-to-PDF Conversion Tool
    Use an online tool like Adobe Acrobat JPG to PDF Converter or Smallpdf. These tools support common image formats like JPG, PNG, and BMP.
  2. Upload the Image
    Click on “Select a file” to upload your image or drag and drop the file into the conversion area.
  3. Create the PDF
    The tool will automatically convert your image into a PDF file. Once complete, click “Download” to save the PDF to your device.
  4. Open the PDF File
    Open the downloaded PDF using a PDF reader (e.g., Adobe Reader). Try copying the text directly if it’s selectable.
  5. Further Processing (If Needed)
    If the text is not immediately selectable because the PDF is flat (image-based), use OCR tools like:
    • Google Drive OCR: Upload the PDF to Google Drive and open it with Google Docs.
    • Tesseract OCR or Smallpdf’s PDF-to-Text Converter: These tools extract text from image-based PDFs.

This method is quick, widely compatible, and works on almost any device. For better results, especially with scanned images or handwritten text, combining it with OCR ensures accurate extraction.

How To Convert Image to Text Using Microsoft Word

Microsoft Word is more than just a document editor — it also offers a simple and convenient way to extract text from images by leveraging its PDF conversion capabilities. This method is ideal for basic needs and doesn’t require third-party software.

  1. Convert the Image to a PDF File
    • Save the image you want to extract text from on your computer.
    • Use tools like the “Print to PDF” feature (built into Windows and macOS) or free online image-to-PDF converters like Smallpdf or Adobe Acrobat Online.
    • Save the image as a PDF file.
  2. Open the PDF in Microsoft Word
    • Launch Microsoft Word.
    • Click File > Open > Browse and locate the PDF file you just created.
    • Select the PDF and open it.
  3. Convert the PDF to Editable Text
    • Microsoft Word will automatically convert the PDF into an editable Word document.
    • This process may take a few seconds to minutes, depending on the size and complexity of the file.
  4. Edit and Save the Extracted Text
    • Once the conversion is complete, the text from the image will appear in a new Word document.
    • You can now:

Converting Image to Text Using Open-Source OCR Libraries

Using open-source OCR libraries like Tesseract (with its Python interface Pytesseract) is a powerful and flexible way to extract text from images. This method is not only free but also highly customizable, making it ideal for handling diverse types of data, such as printed documents, scanned files, or even handwritten text.

Steps to Extract Text Using Open-Source OCR Libraries

1. Install the Required Libraries

Before starting, ensure you have the necessary libraries installed in your Python environment. These include:

  • pytesseract: The interface to access Tesseract OCR.
  • Pillow (PIL): For image loading and manipulation.
  • openai: If you plan to integrate with GPT-4 for further processing.

Use the following command to install:

pip install pytesseract pillow openai

You’ll also need Tesseract OCR installed on your system. Download it from Tesseract’s official GitHub.

2. Extract Text from Images Using Pytesseract

Here is a simple Python script to extract text from an image:

from PIL import Image
import pytesseract

# Function to extract text
def extract_text_from_image(image_path):    
# Load the image using Pillow    
image = Image.open(image_path)    
# Extract text using pytesseract    
extracted_text = pytesseract.image_to_string(image)    
return extracted_text

# Call the function with your image path
text = extract_text_from_image(‘path/to/your-image.jpg’)
print(“Extracted Text:”)
print(text)

3. Enhance and Analyze the Extracted Text Using Large Language Models (LLMs)

After extracting the text, you can use LLMs like GPT-4 to process, summarize, or extract specific details such as invoice numbers, dates, or amounts. This can add significant value for tasks like data entry, content analysis, or automating document workflows.

Here’s an example script integrating GPT-4:

import openai

# Function to process extracted text with GPT-4
def extract_info_with_gpt(extracted_text, api_key):    
prompt = f”””    
Extract the following information:    
1. Invoice Number    
2. Amount    
3. Due Date    
Text:    
{extracted_text}    
“””    

# Set the OpenAI API key    
openai.api_key = api_key    
# Call GPT-4 API    
response = openai.ChatCompletion.create(        
model=”gpt-4″,        
messages=[{“role”: “user”, “content”: prompt}],        
max_tokens=100   
 )    
return response.choices[0].message[‘content’]

# Call the function with extracted text
info = extract_info_with_gpt(text, ‘your-openai-api-key’)
print(“Extracted Information:”)
print(info)
