About formats

PPTX is the default file format for Microsoft PowerPoint presentations since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and later adopted as ISO/IEC 29500. A PPTX file is a ZIP archive containing XML documents that describe slide content, layouts, themes, relationships, and metadata in a structured, human-inspectable hierarchy. Each slide, slide layout, and slide master is stored as a separate XML part, with media assets (images, audio, video) and embedded objects kept in dedicated directories within the package. The XML foundation enables programmatic creation and manipulation of presentations using standard XML tools and libraries — developers can generate, modify, or extract content from PPTX files without requiring PowerPoint itself. One significant advantage is openness and interoperability: the fully documented OOXML specification allows any software to read and write PPTX files, and the format is supported by LibreOffice Impress, Google Slides, Apple Keynote, and numerous other tools. Built-in ZIP compression is another practical strength — PPTX files are typically 50-75% smaller than equivalent PPT files, reducing storage and transfer costs. The format supports all modern PowerPoint features including SmartArt, 3D models, morph transitions, embedded fonts, accessibility metadata, and co-authoring capabilities. PPTX has become the standard interchange format for presentation content worldwide.

JPG is the most common file extension for images compressed with the JPEG standard, published by the Joint Photographic Experts Group as ISO/IEC 10918-1 in September 1992. The three-letter .jpg extension became dominant due to the 8.3 filename limitation of MS-DOS and early Windows, while .jpeg is the full-length variant — both extensions represent identical file contents and compression. JPEG applies lossy compression using the discrete cosine transform (DCT), dividing images into 8x8 pixel blocks, transforming them into frequency coefficients, quantizing to discard visually insignificant data, and entropy-coding the result. Users control the compression level: higher quality retains more detail at larger file sizes, while lower quality achieves dramatic size reduction with increasing visible artifacts in complex textures. The format supports 24-bit true color (16.7 million colors) and 8-bit grayscale, with Exif metadata embedding camera model, exposure settings, orientation, GPS location, and creation timestamp. One advantage is unmatched device compatibility — JPG is the native output format of virtually every digital camera and smartphone, and is displayed by every image viewer, browser, and operating system in existence. Efficient photographic compression is another strength: real-world photographs with smooth gradients and complex textures compress extremely well under DCT, typically achieving 10:1 reduction at high visual quality. JPG images power the vast majority of photographic content across the web, email, social media, and digital archives worldwide.
