What is an OTP file?

An OTP file is a presentation template created by Impress, a presentation program included with Apache OpenOffice (formerly known as OpenOffice.org). It contains a presentation, which includes a master slide as well as a content slide with text, images, shapes, multimedia content, transition effects, and other slide elements. Impress users create OTP files to duplicate .ODP presentations with similar appearance and content.

OpenOffice Impress is a free alternative to Microsoft PowerPoint. Impress's OTP files are similar to PowerPoint's .POT and .POTX templates.

The OTP format is based on the OASIS OpenDocument standard, which uses an XML format to save presentations. Various presentation programs can create OTP files, but most are created by Impress.

You will likely encounter an OTP file only if you use Impress or another OpenOffice user shares a presentation template with you. For example, a co-worker who uses Impress might share an OTP file that contains a branded presentation template with you.

NOTE: The Organization for the Advancement of Structured Information Standards (OASIS) maintains the OpenDocument standard.

How to open an OTP file

You can open an OTP file with various presentation programs, including OpenOffice Impress (cross-platform), LibreOffice Impress (cross-platform), Planamesa NeOffice (macOS), and Collabora Office (multiplatform).
