Edit Metadata View and modify PDF metadata fields including title, author, keywords, dates, and custom properties.

Edit Metadata

Edit the metadata embedded in a PDF file. The tool pre-populates a form with the document's existing metadata, lets you modify any field, and saves the changes into a new PDF.

How It Works

  1. Upload a PDF file. The tool reads its current metadata and populates the form.
  2. Edit any of the standard fields: Title, Author, Subject, Keywords, Creator, Producer.
  3. Adjust the Creation Date and Modification Date using date-time pickers.
  4. Add custom metadata fields by clicking the add button and entering a key-value pair.
  5. Click the process button to save the modified PDF.

Features

  • Pre-fills all existing metadata from the uploaded PDF
  • Standard fields: Title, Author, Subject, Keywords, Creator, Producer
  • Date-time pickers for Creation Date and Modification Date
  • Custom key-value metadata fields for arbitrary properties
  • Saves changes directly into the PDF's document info dictionary

Editable Fields

Field Description
Title The document title displayed in PDF readers
Author The person or organization that created the document
Subject A brief description of the document's topic
Keywords Comma-separated terms for search and categorization
Creator The application that originally created the content
Producer The application that generated the PDF
Creation Date When the document was originally created
Modification Date When the document was last modified
Custom fields Any additional key-value pairs you define

Use Cases

  • Setting a proper title and author before publishing a document
  • Adding keywords to improve searchability in document management systems
  • Updating the modification date to reflect the current revision
  • Adding custom metadata fields like Department, Project ID, or Classification
  • Cleaning up metadata left by the original authoring software

Tips

  • Custom fields are written directly into the PDF's info dictionary. Some PDF readers may not display custom fields, but they are preserved in the file.
  • Leave a field blank to clear it from the metadata. The process button saves whatever is in the form.
  • To view metadata without editing, use View Metadata. To remove all metadata entirely, use Remove Metadata.
