About formats

RTF (Rich Text Format) is a document interchange format developed by Microsoft and first published in 1987 with Word 3.0. The format encodes document content and formatting as plain ASCII text using control words (backslash-prefixed commands) and groups (curly-brace-delimited sections) that describe fonts, character formatting, paragraph layout, tables, images, and page setup. Because RTF is fundamentally a text format with no binary components, documents pass cleanly through any text channel — email systems, clipboard operations, and cross-platform transfers — without corruption. Microsoft designed RTF explicitly as a cross-application and cross-platform exchange format, and it achieved broad adoption: virtually every word processor, text editor, and document tool on every operating system has supported RTF reading and writing for decades. One advantage is exceptional cross-platform compatibility — an RTF document created on any application renders with consistent formatting on any other, making it the most reliable format for text exchange between incompatible systems. The text-based structure provides another benefit: RTF files resist corruption, are trivially generated by programs (requiring only string concatenation), and can be debugged by reading the raw markup in a text editor. While RTF lacks modern features like tracked changes and advanced layout controls, and Microsoft declared the specification frozen at version 1.9.1 in 2008, the format persists as a dependable interchange option where DOCX compatibility cannot be assumed.

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.
