PDF/A is a unique flavor of PDF designed for the long‑term preservation of documents. PDF/A is an ISO‑standardized version of the Portable Document Format (PDF) which is an archival format that embeds all fonts used in the document within the PDF file. PDF/A differs from PDF by prohibiting features such as font linking (as opposed to font embedding) and encryption. Aspose.Cells enables you to save Excel files to PDF/A‑compliant PDF files (PDF/A‑1a, PDF/A‑1b, PDF/A‑2a, PDF/A‑2b, PDF/A‑2u, PDF/A‑3a, PDF/A‑2ab, and PDF/A‑3u are supported).
