ODP Document Format

ODP Converter

ODP is the format used for OpenDocument Presentation files, and this software is a free alternative to Microsoft PowerPoint and Apple Keynote. As the ‘open’ part of its name suggests, it’s an open-source file type that is not owned by a single software company. ODP was developed by OASIS in 2005 and it has ISO accreditation.

While it might not have quite as much functionality, you can use ODP for anything you would normally create with PowerPoint or another presentation program, and it can save you paying for software or needing to use an Apple device or a Google account. Features include the ability to create and deliver presentations with slides that have formatting, animations and transitions. You can also create reports from ODP files. Like other OpenDocument formats, ODP is particularly used with Apache OpenOffice and LibreOffice. ODP files will also open in some other presentation programs, including PowerPoint.

PDF Document Format

PDF Converter

PDF stands for ‘Portable Document Format’ file. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. It is maintained by the International Organisation for Standardization (ISO).

PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. They can be viewed on almost all devices. Creating a PDF can involve compressing a file, making it take up less storage space. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.
