Frequently Asked Questions
1. Is my PDF file uploaded to a server?
No. All metadata modification happens 100% in your browser using the pdf-lib library. Your document never leaves your device, ensuring total privacy for sensitive business or personal files.
2. Does this work with password-protected PDFs?
Currently, encrypted or password-protected PDF files cannot be modified directly due to security restrictions. You must remove the password protection before updating the metadata dictionary.
3. Will updating metadata change the visual content of my PDF?
No. This tool only modifies the internal Information Dictionary of the PDF. The visual layout, text, images, and formatting of your document remain completely untouched.
4. Which metadata fields are most important for SEO?
The Document Title is the most critical field, as search engines often use it as the clickable link in search results. Author and Keywords also help indexers categorize your content more accurately.
5. What is the 'Clean for Sharing' feature?
This feature strips away identifying information such as the original software used (Producer), the creator's username, and timestamps. It replaces them with neutral values to prevent leaking internal process details when sharing documents publicly.
