Frequently asked questions

What is PDF metadata?

PDF metadata is descriptive information stored inside a PDF, such as title, author, subject, keywords, creator application and creation and modification dates. It appears in the Document Properties of PDF viewers and can be used by search tools and screen readers.

Does this page actually edit or compress my PDF?

Not yet. The page currently offers a preview of the workflow with title, author, subject, keyword and optimisation settings, but it does not rewrite your file, so nothing you enter is saved into a PDF. For real page-level changes use the merge, split and rotate tools.

How can I see or change a PDF title and author?

Most desktop PDF viewers show them under File then Properties or Document Properties. Editing usually needs an editor such as Adobe Acrobat, or a command-line tool like exiftool, and changes are saved by writing a new copy of the file.

How do I remove author name and other hidden data from a PDF?

Open the PDF in an editor that supports Sanitize or Remove Hidden Information, or clear the properties fields and save a new copy. Also check the original document, since the author name may live in the Word or design file too.

Does PDF metadata affect SEO?

A little. Search engines can use the PDF title property as the title in results when it is set, so a descriptive title is better than something like Document1.pdf. Metadata is a minor factor compared with the actual content and links to the file.

How do I reduce the size of a PDF file?

Large images are the usual cause, so downsample or compress them in a PDF editor or before you create the PDF. Removing unused pages also helps. The split tool on this site can extract only the pages you need into a smaller new PDF.

Is my data shared when using the PDF Metadata & Compression?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the PDF Metadata & Compression?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.
