Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

What is an SDA file?

SDA is the legacy presentation file format used by StarOffice Impress and early versions of OpenOffice.org, the predecessor suites to today's LibreOffice Impress. It stores slides, layouts, and embedded media using StarOffice's original binary document model, which was later replaced by the OpenDocument Presentation (ODP) standard. SDA files are now mostly encountered when migrating very old StarOffice archives to modern presentation software.

How to open an SDA file

LibreOffice Impress can open SDA files directly thanks to built-in legacy StarOffice format support, automatically converting the content into its modern editing environment. Apache OpenOffice Impress also retains compatibility with this older format.

What is a PPT file?

The PPT format is the legacy binary file standard used by Microsoft PowerPoint from versions 97 through 2003. It utilizes the Compound File Binary Format (CFBF), a structured storage container that organizes data into streams and storages, functioning primarily as a file system within a file. PPT files store presentation data-including text, embedded images, audio, and formatting-in binary records rather than XML, which results in larger file sizes and higher corruption risks compared to the modern OOXML standard.

How to open a PPT file

Modern versions of Microsoft PowerPoint retain backward compatibility for opening and saving PPT files. Native support is also available in macOS via Keynote and in Linux distributions via LibreOffice Impress or OpenOffice Impress. Google Slides provides cloud-based rendering of PPT files, though complex formatting or legacy OLE objects may require conversion to the newer Google Slides format for full editing capabilities.
