Rich Text Format (RTF) is a document file format created by Microsoft in 1987 to let different word processors (on Windows, macOS, etc.) exchange formatted text reliably.

Quick Scoop

  • Core idea: RTF is a text-based format that stores both your words and their formatting (bold, italics, fonts, colors, margins, alignment, etc.).
  • File extension: It usually appears as files ending in .rtf.
  • Goal: Make documents portable between many programs without depending on a single app like Word.

How RTF Works (Simple View)

RTF is essentially a markup language written in plain text, not a binary blob like old .doc files. You can open an RTF file in a basic text editor and see its internal codes.

Inside an RTF file you’ll find:

  • Curly brace groups like { ... } that bundle parts of the document.
  • Backslash control words such as \b (bold) or \i (italic) that turn formatting on or off, often with a number like \b1 (bold on) or \b0 (bold off).
  • A header such as {\\rtf1\\ansi...} that tells software “this is an RTF document and here’s how it’s encoded.”

For example, a snippet like:

{\\rtf1\\ansi ... This is some {\\b bold} text.\\par }

will display as: “This is some bold text.”

What You Can Do With RTF

Most word processors today can open and save RTF files. That makes it handy for:

  • Basic documents: résumés, letters, manuals, simple reports.
  • Sharing text with formatting between different apps and operating systems.
  • Including simple images and objects, depending on the program, along with formatted text.

RTF can store:

  • Bold, italics, underline, superscript, subscript.
  • Fonts, sizes, colors, paragraph alignment, margins.
  • Some graphics and embedded objects in later versions.

Pros and Cons Today

Even though the specification stopped evolving after version 1.9.1 in 2008, RTF is still around but not “trending” like modern formats such as DOCX, HTML, or portable rich text in web CMSs.

Advantages

  • Highly compatible across many word processors.
  • Human-readable text with markup, easier to inspect than binary formats.
  • Good for long-term basic text archiving with simple formatting.

Disadvantages

  • Does not support newer Word features (advanced layouts, modern media, many interactive elements).
  • Specs are frozen, so no new capabilities are being added.
  • File sizes can be larger than some newer, compressed formats.

RTF vs “Rich Text” on the Web

You’ll also see “rich text” used in modern web editors (like CMSes or forum editors) that support bold, lists, images, and embeds in a browser WYSIWYG interface. That rich text concept is broader than the old Microsoft Rich Text Format file type:

  • Web rich text often lives as HTML or a JSON-based rich-text structure, not .rtf files.
  • RTF is specifically the Microsoft-defined file format using backslash codes and curly braces.

Both aim to preserve formatting, but they’re not the same technology. TL;DR: Rich Text Format is an older but still useful Microsoft-defined file format (.rtf) that stores text plus basic formatting in a plain-text, markup-like structure so many different programs can read and write the same formatted document.
