PDF/A files are designed to be accessible no matter what platform, technology or vendor a user employs, ensuring that documents can be viewed long into the future without the need for proprietary technology.
Since PDF/A is based on the ubiquitous PDF standard and a published ISO standard itself, long-term and easy access to content stored in this format is guaranteed.
PDF/A enables storage of metadata and automatic classification of files based on this information, as well as the ability to perform full text searches of not only a single document, but an entire archive.
PDF/A supports compression of files to a fraction of the size of originals, without impairing the quality of the electronic document. The smaller size reduces storage space requirements and facilitates electronic transfers via FTP, e-mail attachment or other means.
