Which PDF metadata fields can I edit?

The title, author and subject. Many viewers show the title in the window bar and search engines may show it for a published PDF, so it is worth setting before you publish or file a document.

Will the original author and software stay in the file?

No. noll rebuilds the document, so the previous author, creating application, producer, dates and XMP metadata are not copied into the export. Only the fields you fill in are written.

Which metadata fields can I edit?

You can edit all standard PDF metadata fields: title, author, subject, keywords, creation date, modification date, creator, and producer. You can also add custom key-value pairs for organization-specific metadata.

Why would I need to edit metadata?

Common reasons include correcting an incorrect author name, adding a proper title for document management systems, setting keywords for search optimization, standardizing metadata across a document set, and updating timestamps after revisions.

Does this change the document content?

No. Metadata editing only modifies the document information dictionary and XMP streams. The visible content, text, images, and layout are not affected in any way.

Can I clear fields to make them empty?

Yes. You can clear any metadata field to an empty value. This is useful when you want to remove specific identifying information while keeping other metadata intact.
