You can set standard fields: Title, Author, Subject, and Keywords. Additionally, you may add custom fields such as Creator, Producer, Creation Date, or any other property that suits your organizational needs.
Absolutely. Keywords are a critical metadata field for SEO. When you upload a PDF to your website or a document repository, search engines use these keywords to index your content. Adding relevant keywords increases the chances of your document being found.
The increase is minimal—typically just a few kilobytes. Metadata is stored as a small text block within the PDF structure, so it does not significantly affect file size.
Yes. Metadata is independent of the document's content. Whether your PDF was created from text, images, or scanned pages, you can add or update its metadata without any issues.
Currently, the tool processes one PDF at a time to ensure precise control. If you need to apply the same metadata to many files, you can upload them individually. For bulk operations, consider using our Merge PDF tool first if appropriate.

Yes. In addition to the standard fields, you can add custom metadata entries. This is useful for including internal document numbers, version info, or any other data you want to store with the PDF.
