What is PDF metadata?
PDF metadata is document property information stored inside the file. It can include title, author, subject, keywords, creator, producer and dates. It is separate from the visible page content.

Edit the Information Stored Inside a PDF
Upload a PDF and update the document title, author, subject and keywords. These fields are not usually visible on the page, but PDF readers, document systems and search tools may show them when you open file properties.
When Metadata Matters
Metadata is helpful when files are archived, shared with a client, uploaded to a document portal or kept in a large folder. A PDF named correctly can still carry an old internal title from Word, InDesign or another app. Editing the metadata keeps the file details consistent with the document you are actually sending.
What Changes
The visible PDF pages are not rewritten or redesigned. PDFem updates standard metadata fields and saves a new copy. To clear existing metadata instead of replacing it, use Remove PDF Metadata.

Frequently Asked Questions
What metadata fields can I edit?
Common editable fields include title, author, subject and keywords. Some technical fields may be created by the software that generated the PDF and may not be useful to edit manually.
Does editing metadata change visible PDF pages?
No. Editing metadata changes document properties, not the text or images shown on the PDF pages. If you need to change visible content, metadata editing is not the right tool.
Why does my PDF show an old title or author?
PDFs often keep metadata from the original document, template, scanner or editor. A file may show an old draft title or a previous author even after the visible pages were changed. Edit the metadata if you want cleaner document properties.
Can editing metadata remove private information?
It can replace common metadata fields, but it does not remove visible private information from the pages. Use Redact PDF for visible sensitive content and Remove PDF Metadata when you want to strip common document properties.
When should I use Remove PDF Metadata instead?
Use Remove PDF Metadata when you do not want the file to carry title, author, subject or keyword values at all. Use Edit PDF Metadata when you want to set those fields to specific new values.
