About formats

PPSX (PowerPoint Slideshow XML) is the Open XML counterpart to the legacy PPS format, introduced by Microsoft with Office 2007. Like PPTX, a PPSX file is a ZIP archive containing XML parts that describe slides, layouts, themes, and media assets according to the Office Open XML specification. The distinguishing characteristic is behavioral: opening a PPSX file launches the presentation directly in full-screen slideshow mode, bypassing the editing environment. This makes PPSX the preferred format for distributing finalized presentations where the audience should experience the content as a seamless visual narrative without exposure to the editing interface, slide sorter, or speaker notes panel. PPSX files support every visual feature available in PPTX including transitions, animations, embedded video and audio, hyperlinks, SmartArt, charts, and custom slide timings. One advantage is streamlined delivery — a PPSX file attached to an email or shared via a link opens as a polished presentation with a single click, requiring no instruction to the recipient. The XML-based foundation provides another benefit: PPSX files are typically much smaller than equivalent PPS files due to built-in ZIP compression, and their contents can be inspected or modified programmatically using standard XML tools. The format is supported for playback in PowerPoint, LibreOffice Impress, Google Slides (after upload), and various mobile presentation apps, ensuring broad cross-platform reach for distributed slide decks.

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.
