OpenDocument text document (.odp)
.odp file signature | application/vnd.oasis.opendocument.presentation
OpenDocument Presentation (ODP) is an open presentation file format defined by the OASIS consortium and standardized by ISO/IEC as part of the OpenDocument family. It is used for slide decks in office suites such as LibreOffice, Apache OpenOffice, and other compatible presentation editors. The format is generally safe, though files from untrusted sources may contain embedded objects or macros in some implementations, so opening them with updated software is recommended.

Frequently Asked Questions
What is a .odp file?
A .odp file is a OpenDocument text document file. OpenDocument Presentation (ODP) is an open presentation file format defined by the OASIS consortium and standardized by ISO/IEC as part of the OpenDocument family. It is used for slide decks in office suites such as LibreOffice, Apache OpenOffice, and other compatible presentation editors. The format is generally safe, though files from untrusted sources may contain embedded objects or macros in some implementations, so opening them with updated software is recommended.
What are the magic bytes for .odp files?
The magic bytes for OpenDocument text document files are 50 4B 03 04 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .odp file?
To validate a .odp file, read the first bytes of the file and compare them against the known magic bytes (50 4B 03 04) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .odp files?
The primary MIME type for .odp files is application/vnd.oasis.opendocument.presentation.
Is it safe to open .odp files?
OpenDocument text document (.odp) 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.
