RTF vs TEXTILE
A detailed comparison of Rich Text Format and Textile Markup — file size, quality, compatibility, and which format to choose for your workflow.

About TEXTILE filesStrengths Comparison
RTF Strengths
- Plain ASCII — portable, grep-able, and diff-friendly.
- Supported by every word processor on every OS since 1990.
- Cannot carry macros or embedded code — relatively safe to open.
- Simple enough to parse by hand or generate with a small script.
- Good interchange format when DOCX compatibility is shaky.
TEXTILE Strengths
- More expressive than Markdown in classical usage (tables, footnotes, classes).
- Mature implementation in RedCloth (Ruby), php-textile, js-textile.
- Core format of Redmine — millions of daily users.
- Clean human-readable syntax.
Limitations
RTF Limitations
- Frozen in 2008 — no modern features (no comments, poor styles, no track changes).
- File sizes are bigger than DOCX for the same content (no compression).
- Images are base64-encoded inline, inflating files further.
- Visual fidelity drifts between Word versions despite the spec.
TEXTILE Limitations
- Market share decimated by Markdown since the mid-2000s.
- Not as widely supported outside the Ruby/Rails ecosystem.
- No CommonMark-style spec — implementations differ on edge cases.
- Rarely added to new projects in 2026.

Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to RTF (frames, legacy macros) may flatten to static content in the target format.
