About formats

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.

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.
