Files with the .ODG extension contain an image defined by sets of points, lines, and curves – a vector graphic. It is an open document format created by the Draw software from the Apache OpenOffice suite. It is used for creating illustrations, logos, and drawings.

The .ODG format is saved in accordance with the OASIS OpenDocument specifications – the data is contained in a universal format based on XML, which ensures full transferability and independence from any platform. All other apps from the Apache OpenOffice suite also save files according to this specification, using ODT, ODF, ODP, and ODS formats – interestingly, this office suite was one of the first to use the OASIS specification.
