Image Compression and Resizing With Python and Pillow

resizer.py

A script for resizing images in a specified directory and saving them to an output directory. The script takes target dimensions as input and processes all images within a given folder, preserving the directory structure.

Requirements

• Python 3.x
• Pillow library (Python Imaging Library)

You can install the required library using pip:

pip install Pillow

Resizing Images

To resize images, follow these steps:

Place Images in the input/ Folder: Put all the images you want to resize in the input directory.

Run the Resizing Script:

You can use one of the provided batch files to run the script.

Using the batch files:

run-resizer.bat: This batch file runs the script with default settings (1920 x 1080).

Example Usage from Command Line:

bash
python resizer.py 1920x1080

This command resizes all images in the input folder to 1920x1080 pixels and saves them in the output folder. Specify whichever resolution you want to use in the script.

Notes:

-Ensure that the input and output directories are correctly set in the resize_images.py script if you need to adjust their paths. -The script currently processes .jpg, .jpeg, .png, and .gif file formats.

Troubleshooting:

-If you encounter issues, make sure the Pillow library is installed and correctly configured. -Verify that the image dimensions provided are valid integers and formatted correctly (e.g., 1920x1080).

compression.py

A script for compressing images in a specified directory and saving them to an output directory. The script compresses all images within a given folder, preserving the directory structure and converting non-JPEG images to JPEG format with a specified quality level.

Requirements

• Python 3.x
• Pillow library (Python Imaging Library)

You can install the required library using pip:

pip install Pillow

Compressing Images

To compress images, follow these steps:

1. Place Images in the input/ Folder: Put all the images you want to compress in the input directory.

2. Run the Compression Script:

You can use one of the provided batch files to run the script.

Using the batch files:

run-compression.bat: This batch file runs the script with default settings.

python compression.py

This command compresses all images in the input folder using a default quality level of 99 and saves them in the output folder. You can adjust the desired_quality variable in the script to set a different quality level.

Notes

• Ensure that the input and output directories are correctly set in the compress_images.py script if you need to adjust their paths.
• The script currently processes .jpg, .jpeg, .png, and .gif file formats.
• JPEG files are copied without additional compression, while other formats are converted to JPEG and compressed.

Troubleshooting

• If you encounter issues, make sure the Pillow library is installed and correctly configured.
• Verify that the desired quality level is an integer between 0 and 100.
