Web App for word to pdf using Flask framework can easily be implemented in python. Many a times in or daily work we require this Web App for word to pdf conversion app. We will explain you the implementation of Web App for word to pdf using Flask framework in Python.
Basic Steps in Web App for word to pdf:
Flask is a lightweight and flexible web framework that allows you to build web applications in Python. It provides a simple and easy-to-use interface for handling HTTP requests and building web pages. To create a web app for Word to PDF using Flask, you’ll need to follow these general steps:
- Install Flask: Start by installing Flask on your machine. You can do this by running the following command in your terminal or command prompt:
- Set up the Flask app: Create a new directory for your project and navigate to it. Inside the project directory, create a new Python file (e.g.,
app.py) to define your Flask application. Import the necessary modules, create an instance of the Flask class, and define a route for the home page. - Create a form: In your Flask app, define a route for the page where users can upload their Word documents. In the corresponding view function, render an HTML template that includes a file input field within a form. This form will allow users to select and upload their Word files.
- Handle file upload: Add another route to handle the file upload request. In the associated view function, retrieve the uploaded file from the request and save it to a temporary location on the server.
- Convert Word to PDF: Use a Python library, such as
python-docxorpywin32, to convert the uploaded Word document to PDF. You can access the uploaded file’s location, read the contents, and convert it to PDF using the library of your choice. - Serve the PDF: Once the conversion is complete, you can either provide a download link to the generated PDF file or directly display it in the user’s browser. For downloading, you can create a new route that returns the PDF file as a response with appropriate headers. Alternatively, you can render a template that includes an embedded PDF viewer to display the converted file.
- Error handling and validation: Implement error handling to deal with cases where the user uploads an invalid file format or encounters any other issues during the conversion process. Perform proper validation to ensure the uploaded file is a Word document before proceeding with the conversion.
- Styling and additional features: Customize the appearance of your web app by adding CSS styles to your HTML templates. You can also consider enhancing the functionality by adding features like file size limitations, progress bars, or support for batch conversions.
Complete implementation of Web App for word to pdf:
- Install Flask:
pip install Flask
- Create a new file named
app.pyand add the following code:
from flask import Flask, render_template, request, send_file
from docx2pdf import convert
app = Flask(__name__)
@app.route('/')
def home():
return render_template('index.html')
@app.route('/convert', methods=['POST'])
def convert_word_to_pdf():
# Get the uploaded file
file = request.files['word_file']
# Check if a file is selected
if not file:
return "No file selected"
# Check if the file has a valid extension
if file.filename.split('.')[-1].lower() != 'docx':
return "Invalid file format. Only Word documents are supported."
# Convert Word to PDF
pdf_file = file.filename.split('.')[0] + '.pdf'
convert(file.filename, pdf_file)
# Return the converted PDF
return send_file(pdf_file, as_attachment=True)
if __name__ == '__main__':
app.run(debug=True)
- Create a new directory named
templatesand create a new file namedindex.htmlinside it. Add the following code to theindex.htmlfile:
<!DOCTYPE html>
<html>
<head>
<title>Word to PDF Converter</title>
</head>
<body>
<h1>Word to PDF Converter</h1>
<form action="/convert" method="post" enctype="multipart/form-data">
<input type="file" name="word_file">
<input type="submit" value="Convert">
</form>
</body>
</html>
- Install the required
docx2pdflibrary:
pip install docx2pdf
- Run the Flask application:
python app.py
Now, if you open your web browser and navigate to http://localhost:5000, you should see a page with a file upload form. Select a Word document and click the “Convert” button. The application will convert the Word document to PDF and prompt you to download the converted file.
Please note that this is a basic implementation, and you may need to add additional error handling, styling, and security measures based on your specific requirements.
