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.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
