  3. Define the conversion parameters: Specify the input PDF file, desired image format (JPEG, PNG, etc.), and other conversion parameters like image resolution and compression level.
  4. Initiate the conversion: Send the request to the Document Server API, which will handle the conversion process.
  5. Retrieve the converted images: The API response will provide you with the location of the converted images, allowing you to download or access them for further processing.

3. Implementing Custom Python Scripts:

For greater customization and control over the conversion process, you can write custom Python scripts using Odoo's framework and libraries.

Steps for implementing custom Python scripts:

  1. Create a new Python module: Create a Python module within your Odoo addons folder.
  2. Import necessary libraries: Import the required Odoo libraries, including the Document Server API and image manipulation libraries like Pillow (PIL).
  3. Write the conversion logic: Implement the conversion logic within your Python script. This involves reading the PDF file, converting it into an image using appropriate libraries, and saving the converted image.
  4. Integrate with Odoo interfaces: Integrate your custom script with Odoo interfaces to trigger the conversion process through buttons, menus, or other user interactions.

4. Leveraging Third-Party Tools:

While Odoo offers robust conversion capabilities, you can also leverage third-party tools for specific needs or preferences.

Steps for using third-party tools:

  1. Choose a suitable tool: Research and select a third-party tool that meets your specific requirements, such as conversion speed, image quality, or integration with other platforms.
  2. Install and configure the tool: Download and install the chosen tool on your system, following the provided instructions. Configure the tool's settings based on your preferences.
  3. Import the PDF files: Import the PDF files into the third-party tool, either directly or through an integrated file manager.
  4. Initiate the conversion process: Start the conversion process using the tool's interface, specifying the output image format, resolution, and other parameters.
  5. Download the converted images: Download the converted images in the desired format, either individually or as a batch.

Choosing the Best Method for Your Needs

The optimal method for converting PDFs to images using Odoo depends on several factors:

There is a different method for converting the PDF files into images and the images into a pdf file. 

1. Install the required Python libraries:

Ensure that the required Python libraries are installed in your Odoo environment. You will need the Pillow library, which provides image processing capabilities. You can install it using the following command:

pip install Pillow

2. Create a new Odoo module or use an existing one:

You can create a custom Odoo module or use an existing one to add the functionality of converting image files to PDF files. If you are using an existing module, proceed to the next step.

3. Define a new model:

In your Odoo module, define a new model that will hold the image file and the converted PDF file. For example, you can create a model called ImageToPdf with fields like name, image, and pdf_file.

4. Create a method to convert images to PDF:

In the model you defined, create a method that will handle the conversion of image files to PDF files. Within the method, use the Pillow library to open the image file, create a new PDF file, and save the image as a PDF document. You can use the following code snippet as an example:

from PIL import Image

def convert_image_to_pdf(self):
for record in self:    image_path = record.image
    image =
    pdf_path = image_path.replace('.jpg', '.pdf')  # Replace with appropriate file extension, 'PDF', resolution=100.0)
    record.pdf_file = pdf_path

5. Add a button or trigger to initiate the conversion:In your Odoo module's view, add a button or trigger (e.g., a form button or a menu item) that will call the convert_image_to_pdf method when clicked. This will initiate the conversion process.6. Test the functionality:Start your Odoo server and navigate to the corresponding view where you added the button or trigger. Upload an image file, and when you click the button or trigger, the image file should be converted to a PDF file and saved in the pdf_file field.7. Adjust the code snippets according to your specific requirements, such as file paths and extensions. Additionally, handle error cases, validations, and any additional functionality you may require for your specific use case.

Converting PDF files into images using Odoo provides a valuable tool for enhancing document presentation, streamlining sharing, and optimizing visual content for various applications.
