When converting a document to PDF/A, the following changes are made to a document:

  1. Graphics will be converted to a device-independent format. If any device dependent color spaces are used, the corresponding color profile will be embedded.
  2. Non-embedded fonts will be embedded.
  3. Transparency will be removed.
  4. Unsupported annotations (e.g., video, audio, 3D) will be removed.
  5. JavaScript – mostly used in Forms – will be removed.
  6. Embedded files and external hyperlinks will be removed.
