What Is an RTF File? How to Open, Edit, and Convert It

November 7, 2026 · 4 min read

You double-click an attachment and there it is: a .rtf file. Maybe it came from an old business system, a teacher, a relative with an ancient copy of Word. Or from WordPad, which used RTF as its default format for decades. Here is what that file actually is, what you can do with it, and how to turn it into a PDF when you need one.

RTF means Rich Text Format

RTF is a document format that Microsoft introduced in 1987 to solve a then-new problem: people wanted formatted documents (bold headings, tables, fonts) to move between different word processors and operating systems without falling apart. The format is managed by Microsoft and its specification has been essentially frozen at version 1.9.1 since 2008, which is a big part of why any program from the last thirty years can still read it.

The idea behind the name: plain text files store only characters, while rich text stores characters plus their formatting — bold, italics, font sizes, colors, margins, tables, and embedded images.

What an RTF file looks like inside

Here is the part that surprises people: an RTF file is not program code — it is the document itself, written out in plain text. The same tiny document, first as you normally see it and then as a simple editor like Notepad shows it:

{\rtf1\ansi Hello \b world\b0}

Everything in red here is a formatting instruction: \b switches bold on, \b0 switches it off. Every instruction is spelled out in plain text, which is exactly why the format is so portable: any program can parse it, on any platform, without needing the software that created it.

This is also why RTF files are larger than their .doc equivalents: the same document spelled out in longhand simply takes more bytes.

How to open an RTF file

Pick whatever you already have:

• Microsoft Word — opens and edits RTF natively; the safest choice for exact formatting.
• LibreOffice Writer — free and open source, handles RTF well on Windows, macOS, and Linux.
• Google Docs — upload the file to Drive and open it; formatting survives the common cases.
• Apple TextEdit or Pages — TextEdit opens RTF directly on macOS; Pages converts it on open.
• WordPad — was Windows' built-in RTF editor for decades, but Microsoft removed it from Windows 11 in the 24H2 update (2024), so it is only an option on older systems.

One warning: don't judge an RTF file by how it looks in a basic text editor — you are seeing the markup, not the formatted document.

RTF vs PDF: the difference that matters

An RTF file describes formatting as instructions, so its final look depends on the program that interprets them: fonts substitute, tables shift, margins move. A PDF freezes the page: it stores the finished layout, which is why it looks identical everywhere and is the expected format for contracts, applications, and anything official.

That difference is the whole reason conversion exists: you write and edit in RTF, you share as PDF.

How to convert an RTF file to PDF

Two dependable routes:

1. In your browser, locally. Install the free RTF to PDF extension for Chrome, click its toolbar icon, drop in your file, press Convert. The file never leaves your device — the conversion runs in the browser, and it works offline.
2. In a word processor. Open the RTF in Word or LibreOffice and use Save As / Export to PDF. Fine when you already have the app open; slower when you just have a file and want a PDF.

Avoid pasting RTF content into online converters when the document is sensitive: contracts, invoices, personal records. Uploading means trusting someone else's server with it; the two routes above keep the file on your machine.
