Transform Your Images: Converting PNG to JPG and JPG to PNG with Python

Converting PNG to JPG using Python

In today’s digital age, images play a crucial role in all forms of communication, be it on social media or websites. The quality and format of an image play a vital role in making it stand out.

If you have a PNG file and need to convert it into a JPG file format, you have come to the right place. In this article, we will walk you through the process of converting a PNG file to a JPG file using Python.

Installing the PIL package

Before we dive into the conversion process, we first need to install an essential package in Python called PIL. The Python Imaging Library (PIL) provides support for the opening, manipulating, and saving of many different image file formats.

To install this package, open your terminal and type the following command:

pip install pillow

Now that we have installed the PIL package let’s move on to the next step.

Capturing the path where the PNG file is stored

To convert a PNG file to a JPG file, we must first find the file path location. The file path location is the address where the PNG file is saved.

We can capture this path by using the os module available in Python. The following code helps you to capture the path where the PNG file is stored.

import os
path = 'C:/Users/user_name/Images/pic.png'

Note: Change the path in the above code to your file path location.

Using Python code to convert PNG to JPG

Now that we have the PIL package installed, and we have captured the file path location let us start writing code to convert a PNG file to a JPG file. We will use the Image module from the PIL package to open the PNG file and then save it as a JPG file.

The following code shows how to use PIL to convert a PNG file to a JPG file.

from PIL import Image

# Open the image and convert it to RGB
with Image.open(path) as im:
    # Change the file format to JPG
    im = im.convert('RGB')
    # Give a new file name and save it in JPG format
    new_file = 'C:/Users/user_name/Images/pic.jpg'
    im.save(new_file, 'JPEG')

Congratulations! You have successfully converted a PNG file to a JPG file using Python.

Example of PNG to JPG Conversion

Let’s implement the code we just learned on a sample image to see how it works. In this example, we have a PNG image in the file path location “C:/Users/user_name/Images/cat.png,” which we will convert to a JPG format.

1. Specifying the PNG file path

import os
path = 'C:/Users/user_name/Images/cat.png'

2. Implementing the Python code to convert PNG to JPG

from PIL import Image
# Open the image and convert it to RGB
with Image.open(path) as im:
    # Change the file format to JPG
    im = im.convert('RGB')
    # Give a new file name and save it in JPG format
    new_file = 'C:/Users/user_name/Images/cat.jpg'
    im.save(new_file, 'JPEG')

3. Generating the new JPG file

After executing the code, a new file with the name cat.jpg will be generated in the specified location C:/Users/user_name/Images/.

Conclusion

Converting a PNG file to a JPG file format using Python can seem daunting at first, but with the steps outlined in this article, you can easily accomplish it. The PIL package is a powerful tool that will enable you to work with images in different formats, manipulate them, and convert them to various formats, including JPG.

We hope that this article has been helpful in guiding you through the process of converting images from one format to another.

Converting JPG to PNG using Python

In the world of digital media, having high-quality images is essential. Images play a significant role in advertising, website design, and social media, among other things.

Often, we need to convert images between different file formats to meet our requirements. This is where Python comes in handy; it provides us with the convenience and flexibility to accomplish this task with ease.

In this article, we will discuss the process of converting JPG to PNG using Python.

Installing the Required Packages

Before we start with the conversion process, we will first need to install the Python Imaging Library (PIL) and the numpy package. To install the required packages, we can execute the following commands in the command prompt:

pip install pillow
pip install numpy

Now that we have installed the required packages, we can move forward with the conversion process.

Converting JPG to PNG

Let us now write a Python script to convert a JPG image to a PNG image. In this example, we will assume that the file path for the JPG file is `”C:/Users/myusername/Images/myphoto.jpg”`.

The steps involved in converting JPG to PNG using Python are as follows:

1. Importing the necessary modules

We first need to import the required modules to perform the conversion.

We will need the Image module from the PIL package and the numpy module.

from PIL import Image
import numpy as np

2. Loading the JPG image

To load the JPG image, we will use the open() function of the Image module and pass in the file path as an argument.

Then, we will use the convert() function to convert the image into a numpy array.

# Load the JPG image
jpg_image = Image.open("C:/Users/myusername/Images/myphoto.jpg")
# Convert the image to a numpy array
jpg_array = np.array(jpg_image)

3. Converting the image to PNG

Lastly, we will convert the JPG image into a PNG format. To accomplish this, we will use the imsave() function from the matplotlib.pyplot module.

This function allows us to save the image in PNG format.

# Convert the JPG image into PNG format
matplotlib.pyplot.imsave("C:/Users/myusername/Images/myphoto.png", jpg_array)

Congratulations! You have successfully converted a JPG image to a PNG image using Python.

Conclusion

Converting JPG to PNG using Python is a simple process that can be accomplished with just a few lines of code. Python’s imaging library, PIL, provides the necessary tools to manipulate images, and the numpy package enables you to work with image data efficiently.

We hope this article has helped you understand the process of converting JPG images into PNG format with Python. In this article, we discussed how to convert PNG to JPG and JPG to PNG using Python.

We started by installing the required packages and capturing the path where the file was stored. Next, we used Python code to convert PNG to JPG.

We then implemented the code to convert a sample image from PNG to JPG. In the next section, we discussed how to convert JPG to PNG and provided an example Python script.

Converting images between file formats is important in various industries, and Python provides a convenient way to accomplish this task efficiently. The main takeaways from this article are that using Python to convert image file formats is a simple process and that Python’s imaging library and the numpy package provide useful tools for image manipulation.
