PDF/A

PDF/A is a specialized version of the standard PDF format designed for long-term digital preservation of documents. Unlike regular PDFs, which may include elements like external fonts or links that can change over time, PDF/A files are self-contained. This means all elements, including fonts and images, are embedded within the file, ensuring that it looks the same regardless of the software or platform used to view it. This makes PDF/A ideal for archiving important documents like legal papers, academic research, or historical records, ensuring they remain accessible and unchanged for many years to come.
