PRONOM Technical Registry PRONOM

PRONOM is the online registry of technical information maintained by The National Archives (UK) for digital preservation professionals. It provides impartial, authoritative data on file formats, software products, and technical components necessary for long-term access to electronic records and digital objects of cultural, historical, or business significance.

The registry supports preservation workflows by enabling identification and management of digital formats. The National Archives offers DROID (Digital Record Object Identification), a complementary automated tool that identifies file formats in digital collections. Together, PRONOM's reference data and DROID's identification capabilities form an integrated resource for institutions managing digital heritage and records.
