ODG (.odg)
.odg file signature | application/vnd.oasis.opendocument.graphics
OpenDocument Graphics (ODG) is a vector graphics file format defined by the OASIS consortium as part of the OpenDocument standard. It is used for diagrams, illustrations, flowcharts, and page-layout graphics in applications such as LibreOffice Draw, Apache OpenOffice, and Calligra. The format is generally safe to open, though files from untrusted sources should still be handled carefully because they may contain embedded objects or external references.

Frequently Asked Questions
What is a .odg file?
A .odg file is identified by the magic bytes 50 4B at byte offset 0. OpenDocument Graphics (ODG) is a vector graphics file format defined by the OASIS consortium as part of the OpenDocument standard. It is used for diagrams, illustrations, flowcharts, and page-layout graphics in applications such as LibreOffice Draw, Apache OpenOffice, and Calligra. The format is generally safe to open, though files from untrusted sources should still be handled carefully because they may contain embedded objects or external references.
What are the magic bytes for .odg files?
The magic bytes for ODG files are 50 4B at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .odg file?
To validate a .odg file, read the first bytes of the file and compare them against the known magic bytes (50 4B) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .odg files?
The primary MIME type for .odg files is application/vnd.oasis.opendocument.graphics.
Is it safe to open .odg files?
ODG (.odg) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
