Why Edit PDF Metadata?
Metadata tells the story of your document - who created it, when, and what it's about. Proper metadata improves organization, searchability, and can protect your privacy.
Metadata Fields Explained
- Title: Document name displayed in search results and file properties.
- Author: Creator's name - important for attribution or privacy.
- Subject: Brief description of document content.
- Keywords: Tags that help with searching and categorization.
Privacy Consideration
PDFs can reveal personal information through metadata - your name, company, computer name. Clear metadata before sharing sensitive documents to protect your privacy.
常见问题
What is PDF metadata?
PDF metadata includes properties like title, author, subject, keywords, creation date, and modification date that describe your document.
Why should I edit PDF metadata?
Edit metadata to organize documents, improve searchability, remove personal information for privacy, or provide proper attribution.
Will editing metadata change my document content?
No, editing metadata only changes document properties. The actual content, text, and images remain completely unchanged.
Is editing PDF metadata free?
Yes, our metadata editor is completely free with no registration, watermarks, or hidden costs.
Can I remove all metadata for privacy?
Yes, clear all metadata fields to remove author information, creation dates, and identifying details before sharing documents.
What metadata fields can I edit?

How do I view current metadata?
Upload your PDF and the tool displays all existing metadata. In most PDF readers, go to File > Properties to view metadata.
Why would I add keywords to a PDF?
Keywords help with document organization and searchability. Search tools and document management systems use keywords to find relevant files.
Can I batch edit metadata for multiple PDFs?
Currently, edit one PDF at a time. For multiple files, process each individually or use our Merge tool first to combine them.
Does metadata affect file size?
Metadata has negligible impact on file size - typically just a few kilobytes regardless of how much information you add.
