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.

PPT Technical Info

What is a PDF/A file?

PDF/A is an ISO-standardized (ISO 19005) variant of the PDF format designed specifically for long-term digital archiving. It embeds all fonts, color profiles, and metadata directly inside the file and prohibits external dependencies, encryption, and JavaScript, ensuring the document will render identically decades from now regardless of which software or fonts are available on the viewing system. It's widely required for legal, government, and institutional record-keeping.

How to open a PDF/A file

PDF/A files open in any standard PDF viewer, including Adobe Acrobat Reader, Apple Preview, and built-in browser PDF viewers, since the format is fully backward-compatible with regular PDF readers. Dedicated archival software such as Adobe Acrobat Pro can also validate that a file meets PDF/A compliance.
