Brunno Klosowski - PDF Metadata Editor

PDF Metadata Editor

2025 / Python

Coding project for daily task automation utilizing Python and the pypdf library.

When exporting PDFs from Google Docs, the files often retain the default title metadata ending in " - Google Docs". This can appear unpolished, especially when sharing via Google Drive, where the title metadata is visible to recipients.

To simplify this, I developed a Python script using the pypdf library to overwrite the PDF title metadata with a clean, custom name. The script reads the original file, updates the metadata and safely replaces the file, making it ideal for refining portfolios or official documents.

Code

# Importing libraries

import os

from pypdf import PdfReader, PdfWriter

# Variables

file_name = "Portfolio"

# Base path

base_path = f"G:\\Meu Drive\\04_Professional\\02_CV\\06_2025\\{file_name}"

# File paths

input_path = f"{base_path}\\{file_name}.pdf"

temp_path = f"{base_path}\\{file_name}_temp.pdf"

# Overwrite PDF metadata

reader = PdfReader(input_path)

writer = PdfWriter()

for page in reader.pages:

writer.add_page(page)

writer.add_metadata({

"/Title": f"{file_name}"

})

with open(temp_path, "wb") as f:

writer.write(f)

os.replace(temp_path, input_path)

print("PDF metadata overwritten successfully.")
