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.
Technical Specifications
| Specification | .RTF | .TEXTILE |
|---|---|---|
| MIME type | application/rtf | text/x-textile |
| Extensions | .rtf | .textile |
| Standard | RTF Specification 1.9.1 (2008) | — |
| Character set | ASCII with Unicode escapes (\u) | — |
| Implementations | — | RedCloth (Ruby), php-textile, js-textile |
| Primary users | — | Redmine, Textpattern, early Rails |
| Encoding | — | UTF-8 |
Strengths 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.
Frequently Asked Questions
RTF (Rich Text Format) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.
TEXTILE (Textile Markup) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.
Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most RTF files with reasonable fidelity. If your installed software does not support RTF, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.

Upload the RTF to KaijuConverter and pick DOCX, PDF, ODT, RTF, HTML, Markdown, or plain text. Our pipeline runs LibreOffice headlessly plus pandoc for text formats — the same engines behind professional document pipelines. Styles, tables, images, and hyperlinks survive the conversion intact.
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.
