Reduce PDF Size - bg3075 - Apr-16-2024
This code prompts the user for an input & output path/filename, and compresses the original PDF. This is a huge asset when working with PDF images that are a large size by default. Must have Ghostscript(GS) installed, and hardcode the path to the GS installation in line eight (ghostscript_path =). For use with Python 3.
import subprocess
import os
from pathlib import Path
def compress_pdf_file(input_path, output_path):
try:
# Specify the path to Ghostscript executable (gswin32c or gswin64c)
ghostscript_path = "C:\\Program Files\\gs\\gs10.03.0\\bin\\gswin64c" # Adjust this path as needed
subprocess.call([
ghostscript_path,
"-q",
"-sDEVICE=pdfwrite",
"-dCompatibilityLevel=1.3", # Set PDF version to 1.3
"-dPDFSETTINGS=/prepress", # Optimize for prepress quality
"-dNOPAUSE",
"-dBATCH",
"-sOutputFile=" + output_path,
input_path,
])
