HOE PPTX
IS ONTSTAAN.

1987
2007

PPTX shipped with Office 2007, the same release that introduced the ribbon interface and the Office Open XML family (DOCX, XLSX, PPTX). Under the hood it is a ZIP archive containing XML files: one for each slide, one for the master, one for themes, and a /media folder for embedded images, videos, and sounds. The old binary .ppt format, dating from 1987, was retired as the default.

PowerPoint itself was born not at Microsoft but at Forethought, Inc. in Silicon Valley in 1987. Microsoft bought the company three months after version 1.0 shipped. Four decades later PPTX is the de-facto currency of corporate decks, academic talks, and investor pitches — despite a cottage industry of would-be replacements (Keynote, Google Slides, Pitch, Beautiful.ai).

WEETJES &
TRIVIA.

01

A .pptx is literally a ZIP — rename it to .zip and you can browse each slide as its own XML file.

02

Every embedded image, font, video and sound lives in /ppt/media/ inside the archive.

03

PowerPoint was invented at Forethought in 1987; Microsoft acquired the company for $14 million three months after launch.

04

The spec is over 5 000 pages (ECMA-376) — longer than most novels; few editors implement 100% of it.

05

Animations and transitions are encoded as XML sequences — in theory portable, in practice often broken when opened outside PowerPoint.

STERKE PUNTEN &
BEPERKINGEN.

Sterke punten

  • ~75% smaller than the legacy binary .ppt thanks to ZIP compression.
  • Human-readable XML inside — easy to script, patch, or diff.
  • Cross-compatible with Keynote, Google Slides, LibreOffice Impress (with minor drift).
  • Preserves master slides, themes, animations, notes, and embedded media.
  • ISO/IEC 29500 standardized — vendor-independent on paper.

Beperkingen

  • Animations and transitions often render differently outside Microsoft PowerPoint.
  • Embedded fonts and media balloon file sizes rapidly.
  • Complex layouts drift subtly when round-tripped through non-Microsoft editors.
  • Older .pptm macro-enabled variants are a malware vector via VBA.
