Welcome to the PDF Compression Shell Scripts repository! Here, you'll find shell scripts designed to compress PDF files efficiently. These scripts are tailored to help you reduce the size of your PDF documents while preserving quality and readability.

Usage

Prerequisites

Before using these scripts, ensure you have the following prerequisites installed on your system:

• Ghostscript

Installation

1. Clone this repository to your local machine:

   git clone https://github.com/interdevel/pdf-compress.git

2. Navigate to the cloned directory:

   cd pdf-compress

Running the Scripts

Basic Compression

To compress a single PDF file, run:

./compress-pdf-single.sh input_file.pdf output_file.pdf

Replace input_file.pdf with the path to your input PDF file and output_file.pdf with the desired name for the compressed PDF. If no output_file.pdf is given, the script will create the output file appending the suffix "-compressed-TIMESTAMP" to the original file name.

Batch Compression

To compress multiple PDF files in a directory, run:

./compress-pdf-multiple.sh input_directory/ output_directory/

Replace input_directory/ with the path to the directory containing the input PDF files and output_directory/ with the desired directory for the compressed PDF files.

Options

These scripts will offer customizable options in future versions:

• -q <quality>: Specify the compression quality (default is 80). Higher quality results in better readability but larger file sizes.
• -d <dpi>: Set the DPI (dots per inch) for the output PDF (default is 300).
• -f: Overwrite the output file if it already exists.

Example

./compress-pdf-single.sh -q 70 -d 150 input.pdf output.pdf

This command compresses the input.pdf file with quality set to 70 and DPI set to 150, saving the compressed PDF as output.pdf.

Contributions are welcome! If you have any suggestions or improvements for these scripts, feel free to open an issue or submit a pull request.
