About formats

PPT is the binary file format of Microsoft PowerPoint, the presentation software first released on April 20, 1987 for the Apple Macintosh and later ported to Windows. The PPT format stores presentations as OLE2 compound documents — a structured binary container developed by Microsoft that organizes slides, text content, images, charts, animations, transitions, speaker notes, and embedded objects across multiple internal streams. Each slide is composed of shape records describing text boxes, auto-shapes, images, tables, and other elements with associated formatting properties including fonts, colors, positioning, and animation sequences. The format evolved substantially through multiple PowerPoint versions, with the PowerPoint 97 release establishing the compound document structure that remained standard through PowerPoint 2003. One advantage is universal recognition — PPT files are understood by virtually every presentation application across all platforms, from Microsoft Office to LibreOffice Impress, Google Slides, and Apple Keynote, making it one of the most portable document formats ever created. The format's mature feature set is another strength: PPT files support complex slide masters, custom animations with timing sequences, embedded multimedia, OLE-linked objects, and VBA macros for automation. Although Microsoft introduced the XML-based PPTX format with Office 2007, the binary PPT format remains widely encountered in archived presentations, corporate document repositories, and organizations that maintain compatibility with older PowerPoint versions.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.
