In this article, we will explore the process of converting WebP images to the widely supported JPEG format using Python.

Why Convert WebP to JPG?

While WebP offers numerous advantages such as smaller file sizes and better image quality, it may not be supported by all platforms and software. Some older web browsers and image editing tools may not be compatible with this format. By converting WebP images to JPEG, you can ensure maximum compatibility across various platforms, making your images accessible to a wider audience.

Python: A Powerful Language for Image Conversion

Python, a versatile and widely-used programming language, provides a plethora of libraries and modules for image processing tasks. Two popular libraries that we will use for the WebP to JPG conversion are Pillow and PyWebP.

Pillow is a powerful Python imaging library that allows us to open, manipulate, and save various image formats, including WebP and JPEG. PyWebP, on the other hand, provides an interface to the WebP library, enabling us to convert WebP images to other formats.

Installing Required Libraries

To get started, you need to install both Pillow and PyWebP libraries. Open your terminal or command prompt and run the following commands:

“`
pip install Pillow
pip install PyWebP
“`

Once the libraries are installed, we can proceed with the image conversion.

Converting WebP to JPG using Python

To convert a WebP image to JPEG, we first need to open the WebP image using the Pillow library. Here’s a basic example:

“`python
from PIL import Image

image = Image.open(‘image.webp’)

# Further image processing can be applied here

image.save(‘image.jpg’, ‘JPEG’)
“`

In the example above, we import the Image module from the Pillow library and open the WebP image using the `Image.open()` function. You need to specify the path to your WebP image, for example, `’image.webp’`. After opening the image, you can apply further processing or manipulations, such as resizing, cropping, or applying filters. Finally, we save the image in JPEG format using the `image.save()` function.

Handling Multiple WebP Images

If you have multiple WebP images that need to be converted, you can use a loop to automate the conversion process. Here’s an example:

“`python
from PIL import Image
import os

input_folder = ‘webp_images/’
output_folder = ‘jpg_images/’

webp_images = os.listdir(input_folder)

for image_file in webp_images:
if image_file.endswith(‘.webp’):
image_path = os.path.join(input_folder, image_file)
image = Image.open(image_path)

# Further image processing can be applied here

jpg_path = os.path.join(output_folder, os.path.splitext(image_file)[0] + ‘.jpg’)
image.save(jpg_path, ‘JPEG’)
“`

In this example, we assume that your WebP images are stored in the `webp_images/` folder. We create an output folder `jpg_images/` to store the converted JPG images. The `os.listdir()` function is used to get a list of all files in the input folder, and then we loop through each file. The `os.path.join()` function helps in creating the paths for input and output files. After opening each image, you can apply any required processing and save it as a JPEG file with the same name in the output folder.
