TL;DR<\/h2>\n

PDF metadata is information stored with a PDF that describes the document, such as its title, author, subject and keywords. For accessibility, two document properties deserve particular attention: the document title and default language.<\/p>\n

    \n
  • A descriptive document title helps users identify the PDF without relying on an unclear filename.<\/li>\n
  • The default language setting helps screen readers apply the correct pronunciation rules.<\/li>\n
  • You can usually review and edit these properties in your PDF editor or set them in your authoring tool before export.<\/li>\n
  • Accessibility checkers can flag missing or incorrect title and language settings before the PDF is published.<\/li>\n <\/ul>\n<\/div>\n\n\n\n

    A PDF contains more information than the text and visuals you see on the page. It also stores details about the document itself, including its title, author, subject and language. This information is known as PDF metadata.<\/p>\n\n\n\n

    Most of these details are easy to overlook, but some play an important role in accessibility. The document title helps screen reader users identify what they\u2019ve opened, while the language setting helps the screen reader pronounce the content correctly.<\/p>\n\n\n\n

    For example, without a descriptive title, someone may hear a filename like “report_final_v2.pdf” instead of \u201c2026 Annual Report.\u201d A missing or incorrect language setting can also affect how the document is read aloud.<\/p>\n\n\n\n

    In this article, I’ll explain what PDF metadata is, why it’s important for accessibility and how you can edit it.<\/p>\n\n\n\n

    What is PDF metadata?<\/strong><\/h2>\n\n\n\n

    PDF metadata is information stored with a PDF that describes the document. It can tell you what the document is called, who created it, what it is about and when it was last modified.<\/p>\n\n\n\n

    Common PDF metadata includes the document title, author, subject, keywords, creator and creation or modification dates. You may also see the document language alongside these properties when checking a PDF for accessibility.<\/p>\n\n\n\n

    PDF metadata is separate from the content you see on the page. For example, a file named annual_report_final_v3.pdf might have a document title of 2026 Annual Report, list Acme Inc. as the author and use Annual financial performance as its subject. None of those details need to appear on the page itself to be stored with the PDF.<\/p>\n\n\n\n

    Why does PDF metadata matter for accessibility?<\/strong><\/h2>\n\n\n\n

    Metadata is used to provide context about a PDF that may not be obvious from the page itself, so that PDF viewers, screen readers and other assistive technologies can identify the document and interpret certain parts of it correctly.<\/p>\n\n\n\n

    Some document properties therefore have a direct accessibility impact. The document title helps users identify the PDF they have opened, while the default language helps screen readers pronounce the content correctly.<\/p>\n\n\n\n

    These two properties also map to specific WCAG requirements. WCAG 2.4.2: Page Titled requires documents to have titles that describe their topic or purpose, while WCAG 3.1.1: Language of Page requires the default language to be programmatically identified.<\/p>\n\n\n\n

    Other metadata fields have a more indirect role<\/strong>. Details such as the author, subject and keywords can make a document easier to identify, organize or find, but they do not affect how a screen reader interprets the document in the same way.<\/p>\n\n\n\n
