About this tool

PDF Metadata Viewer reads the metadata baked into any PDF and shows it in a clean, copy-friendly layout, without uploading the file. The tool reads the PDF with file.arrayBuffer(), locates the trailer's /Info indirect reference, follows it to the Document Information dictionary, and decodes the standard string entries the PDF specification defines: Title, Author, Subject, Keywords, Creator (the application that wrote the document, for example Microsoft Word), Producer (the library that emitted the PDF, for example Adobe PDF Library), CreationDate, ModDate, and the Trapped flag. PDF strings come in three flavors and they are all handled: literal strings in parentheses with backslash escapes and octal codes, hexadecimal strings in angle brackets, and any of those wrapped in a UTF-16 BE BOM (FE FF) or PDFDocEncoding so accented characters and non-ASCII titles render correctly. PDF dates use the (D:YYYYMMDDHHmmSSO'HH'mm') form and are reformatted into a readable timestamp while the literal value is preserved underneath. Newer PDFs ship XMP metadata, a packet of plain XML containing dc:title, dc:creator, dc:description, xmp:CreatorTool, xmp:CreateDate, xmp:ModifyDate, pdf:Producer, and PDF/A claims (pdfaid:part and pdfaid:conformance). The tool detects the packet, surfaces a copyable excerpt, and backfills any Info fields the Document Information dictionary did not include. Beyond metadata, the viewer reports the PDF version declared in the file header, the total page count derived from the /Pages tree (with a leaf-page fallback for files whose catalog lives in a compressed object stream), whether the document is encrypted (password-protected), and whether it is linearized for fast web view. All of this is useful when auditing a stack of PDFs for archival quality, double-checking that a tool you used did not leave personal information in the Author field, identifying which program generated a vendor document, spotting whether an upload claims PDF/A compliance, confirming a PDF was last touched at the expected time, or simply reading the title a PDF claims so it can be renamed correctly on disk. Nothing leaves the tab; the file is read into memory, scanned, and released.
