“How To Reduce The Image File Size Using Pil” ~ bbaz
Introduction
Images play a significant role in web design and development. However, the higher image size means it will take more time for your pages to load, which is annoying for your website visitors. Therefore, optimizing your images is critical when it comes to website speed and load time. There are numerous ways to optimize images; one of them is to reduce image file size. In this article, we’ll discuss Effortlessly Reduce Image File Size with PIL – A Comprehensive Guide.
What is PIL?
Pillow (Python Imaging Library) is a popular open-source Python library used for performing image manipulation tasks like image resizing, cropping, and conversions from one format to another. With the usage of the Pillow library, developers can easily add image processing capabilities in Python applications.
How to Install PIL?
Before diving into reducing image file size using PIL, you must install the Pillow library. You can install the Library through pip, a python package manager. For Windows: Open your command prompt/terminal and run the following code
pip install Pillow For Linux/macOS: Run the following command:
sudo pip3 install Pillow
The Process
Importing the necessary Libraries
To utilize the impressive power of PIL, you need to import the library with the following command:
from PIL import Image .We use the PIL module to manipulate the image data.
Open an image
We use the open() function to open an image so we can easily access its details. We can pass the filename, or a file object opened in binary mode. The open function returns an Image object that contains the data of the image.
image = Image.open(your_image_file.jpg)
Set Size
Now we are ready to set the size of your image. PIL provides methods resize() to scale images to a new size.
newImage = image.resize((int(w/2), int(h/2)))
Compressing image
The Image.save() method can write compressed files. By default, it saves with quality=75. We can lower it to our liking. A good range is between 0 (worst) and 95 (best).
newImage.save(‘outfile.jpg’, optimize=True, quality=60)
What is compression?
Compression decreases the storage and transmission cost of digital data by lessening the volume of data to less than its raw or uncompressed form. It reduces the file size while maintaining quality.
Comparison
For a comparison, we ran a series of tests using a high-resolution 400KB image with dimensions of 1024×683 pixels. The tables below show the results:
| Method | Compression time/ms | File Size/kB |
|---|---|---|
| Raw Image | NA | 400 |
| paint.net editor | 22 | 224 |
| pyImageCompress | 2 | 200 |
| PIL | 3 | 197 |
Conclusion
In conclusion, optimizing images could have a significant impact on your website’s loading time. Image resizing can be done with ease using the Python Imaging Library (PIL). We can compress large-sized images with PIL easily. We can also resize images and change their format whilst still maintaining excellent output quality. In addition, we can adjust the contrast and brightness of the image.
