About the RTF format
RTF is Microsoft's 1987 rich-text format, and it refuses to die for a good reason: the file is plain ASCII with readable backslash commands, so any program ever written can open it. WordPad, Word, TextEdit, LibreOffice, ancient mainframe editors — RTF is the lowest common denominator of formatted text.
It carries bold, italics, fonts, colors, tables and images, but its layout fidelity is modest by design — think "formatted text", not "typeset page". That makes RTF the right target when the recipient's toolchain is unknown, ancient or locked down: it opens everywhere and keeps the formatting that matters.
+ Strengths
- ✓Opens in literally every word processor
- ✓Plain-text based — never corrupted by email or old systems
- ✓Keeps bold/italic/tables/images without a full office suite
! Limitations
- −No templates, macros or document automation
- −Layout fidelity far below DOCX/PDF
- −Verbose encoding makes files larger than DOCX
About the EPUB 3 format
EPUB is the open standard of e-books (IDPF, now W3C): a ZIP package of XHTML chapters, CSS styling and metadata, rendered reflowably on any screen size. Text re-wraps to your phone, your e-reader and your monitor; font size, margins and typography belong to the reader, not the publisher. EPUB3 adds fixed-layout support, media overlays (read-aloud) and rich semantics.
It is the universal format of every ebook platform except Kindle (Amazon accepts EPUB uploads since 2022 but converts internally). DRM is optional — many EPUBs are open, library books use Adobe ADE encryption. For text-centric books it is the right long-term choice; heavily designed print layouts survive conversion imperfectly.
+ Strengths
- ✓Reflows to any screen — the point of e-books
- ✓Open standard, future-proof, tool-rich
- ✓Accepted by every store and reader app
! Limitations
- −Kindle devices still need conversion to Kindle formats
- −Complex print layouts translate imperfectly
- −DRM variants need specific readers
