Why does PDF metadata matter? What does your PDF\u2019s metadata say about your PDF?&nbsp;<\/p>\n\n\n\n<p>PDF metadata, and all metadata in general, is the data that describes other data. Remember that PDFs and other file formats (DOC, XLS, etc.) are simply ways that computers store and organize information. Metadata provides additional details about this information. Some examples of metadata about a PDF include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When a PDF was created<\/li>\n\n\n\n<li>The title of the PDF<\/li>\n\n\n\n<li>Who created the PDF<\/li>\n\n\n\n<li>When the PDF was last modified<\/li>\n\n\n\n<li>Keywords about the PDF<\/li>\n<\/ul>\n\n\n\n<p>Most PDFs contain this metadata, but how is this metadata used?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is PDF Metadata Used For?<\/strong><\/h2>\n\n\n\n<p>Here are a few common usages for PDF metadata.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PDF searching<\/h3>\n\n\n\n<p>Search engines like Google and Bing let you search not only for information, but for specific types of documents. This is especially useful if you need particular types of sources (such as academic or governmental) or want to search for specific formats, like eBooks. Search engines use metadata to display documents in your search results based on the keywords that you searched for. Websites also contain metadata that search engines use to give you more accurate results. Below shows a search for \u201chow to make a paper airplane,\u201d showing the type of metadata that Google used to find it, indicated by the green arrows.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1016\" height=\"421\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image6.png\" alt=\"A google search shows results for how to make a paper airplane with green arrows pointing to metadata and schema markup for the title tag, headline and meta description. \" class=\"wp-image-7950\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image6.png 1016w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image6-300x124.png 300w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image6-768x318.png 768w\" sizes=\"auto, (max-width: 1016px) 100vw, 1016px\" \/><\/figure>\n\n\n\n<p>If you want to search specifically for PDF formats, enter the phrase \u201cformat:pdf\u201d:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"475\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image10-1024x475.png\" alt=\"A google search for how to make a paper airplane format PDF shows green boxes around the PDF identifiers.\" class=\"wp-image-7951\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image10-1024x475.png 1024w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image10-300x139.png 300w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image10-768x356.png 768w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image10.png 1029w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Storing and identifying PDFs<\/h3>\n\n\n\n<p>When you store or archive documents, whether in the <a href=\"https:\/\/pdf.live\/resources\/other\/cloud-storage-pdfs\/\">cloud<\/a> or on a hard drive, each document\u2019s metadata will make it easier to search for them based on metadata such as key terms, authors, and title. The PDF file format is strong because it\u2019s versatile, but the words and information that it contains may not be readable to a computer (especially if it was <a href=\"https:\/\/pdf.live\/resources\/other\/what-optical-character-recognition-ocr-means\/\">scanned<\/a>, for example). Metadata helps a computer find PDFs based on the terms that you search for by crawling through your files\u2019 metadata.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PDF accessibility<\/h3>\n\n\n\n<p>Screen readers and other accessibility tools rely on a PDF\u2019s internal structure and tagging \u2014 not just metadata \u2014 to interpret and navigate the document. While basic file metadata (such as file type or extension) helps systems recognize a file as a PDF, <a href=\"https:\/\/pdf.live\/resources\/working-with-pdfs\/accessibility\/\">accessible PDFs<\/a> go further by including structured elements like tags, headings, and alternative text for images. These features allow assistive technologies to provide a meaningful reading experience for people who have visual impairments. While some metadata (like document title or language) can support accessibility, it\u2019s tags and structure within the PDF that matter most.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Version control<\/h3>\n\n\n\n<p>If you&#8217;re collaborating on a PDF with another writer or publisher, having a record of edits is important to track when changes were made and by whom. PDF metadata can store information such as the document&#8217;s creation and modification dates, and the author&#8217;s name. While metadata alone doesn\u2019t track every edit like version control software, it can help multiple writers monitor basic details about changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Do I View PDF Metadata?<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">View PDF metadata on Windows PCs<\/h3>\n\n\n\n<p>PDF metadata can be viewed using a PDF reader such as Adobe Acrobat. While you can view a document\u2019s information using your computer\u2019s file explorer, this will only contain the info about the local version of your PDF, not the PDF itself.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open the PDF using <strong>Adobe Acrobat<\/strong> or another PDF reader.&nbsp;&nbsp;<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"688\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image7-1-1024x688.png\" alt=\"Document properties for DPF BOOkmark Sample are visible showing the author is Accelio Corporation\" class=\"wp-image-7952\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image7-1-1024x688.png 1024w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image7-1-300x202.png 300w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image7-1-768x516.png 768w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image7-1.png 1525w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li>Click the <strong>Menu<\/strong> on the top left and click <strong>Document properties<\/strong>.&nbsp;<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"376\" height=\"746\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image9-1.png\" alt=\"A menu shows options for document properties in Acrobat\" class=\"wp-image-7953\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image9-1.png 376w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image9-1-151x300.png 151w\" sizes=\"auto, (max-width: 376px) 100vw, 376px\" \/><\/figure>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>View the metadata of your PDF!<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"605\" height=\"692\" src=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image5-2.png\" alt=\"Document properties for DPF BOOkmark Sample are visible showing the author is Accelio Corporation\" class=\"wp-image-7954\" srcset=\"https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image5-2.png 605w, https:\/\/pdf.live\/resources\/wp-content\/uploads\/2025\/05\/image5-2-262x300.png 262w\" sizes=\"auto, (max-width: 605px) 100vw, 605px\" \/><\/figure>\n\n\n\n<p>Here, we see the PDF\u2019s title, the authors, when it was created, and last modified.
