Metadata Architecture
XMP & Info Dictionary
PDFs store data in two places: the legacy Info Dictionary and the modern XML-based XMP stream. Our viewer parses both to ensure you see every hidden tag, from copyright notices to GPS data.
Local Byte-Scanning
By scanning the file bytes locally via WASM, we identify metadata even if the file is partially corrupted or lacks a proper cross-reference table.
