PDF Document Metadata Online Editor
Frequently Asked Questions
Where is PDF file metadata stored?
PDF metadata is stored in the document information dictionary (Info Dictionary) in the PDF header, including standard fields such as title, author, subject, keywords, creation date, and modification date.
Will metadata be preserved after converting Word to PDF?
Possibly. When converting DOCX to PDF, some metadata (such as original creator and company name) may be transferred to the PDF property fields. It is recommended to clear sensitive information before conversion or use the PDF metadata editor.
How to completely clear all hidden information in a PDF?
Upload your PDF file, clear all property fields in the editor, save and download. The tool uses the pdf-lib library to directly manipulate the PDF structure, ensuring information is completely removed.
Do I need to upload files to edit PDF properties online?
No upload to any server is required. This tool runs locally in your browser, using web technologies to process PDF files directly on the client — your files remain on your device at all times.
