How to Edit PDF Metadata: Title, Author, Subject and Keywords

When you open a PDF, the tab or title bar often shows a strange name: an old draft title, a file name, or nothing at all. That text comes from the document's metadata.

Setting it properly makes your file look professional and easier to find, and it lets you control which details you share.

This guide explains what you can change with TAMPDF's Edit PDF Metadata tool and why it matters.

What Is PDF Metadata?

Metadata is information stored inside a PDF about the document itself. The fields you can edit are the title, author, subject, keywords, creator and producer. PDF readers, search engines and file managers display them.

Why Edit Metadata?

• A clear title shows up in the reader's title bar and in search results.
• A correct author makes ownership clear.
• Subject and keywords help organise and find documents.
• Removing outdated or private values avoids sharing details by accident.
• Consistent metadata makes a set of documents look professional.

How to Edit PDF Metadata With TAMPDF

1. Open the Edit PDF Metadata tool.
2. Drag your PDF into the upload area, or choose it from your device. The current properties are shown.
3. Change the fields you want: title, author, subject, keywords (separated by commas), creator and producer.
4. To remove a property, clear its field. Empty fields are removed from the file.
5. Press Edit metadata and download the result.

What Stays the Same?

Only document properties change. Pages, text and images stay exactly the same, and the edit is made in your browser, so the file is not uploaded.

Edit or Remove?

If you want your own clean title and author, edit the fields. If you want no properties at all, remove the metadata instead. To see what a file currently contains, open it in PDF Info.

Tips for Best Results

• Write a descriptive title, not a file name.
• Separate keywords with commas and keep them relevant.
• Do this as the last step, after merging or compressing the file.
• Save the result under a new name so you can keep the original.

Common Mistakes to Avoid

Leaving the old title

A copied template may still carry a previous project's title. Always check it before sharing.

Stuffing keywords

A handful of accurate keywords is better than a long list of unrelated ones.

Editing before other changes

If you merge or edit the file afterwards in another program, it may overwrite your metadata.

Frequently Asked Questions

Why edit PDF metadata?

Conclusion
