What Is an RTF File? A Complete Guide for Business and Security Professionals

Updated on September 10, 2025, by Xcitium

Have you ever come across a document ending with .rtf and wondered, “What is an RTF file?” Many business leaders, IT managers, and cybersecurity professionals encounter RTF files daily without realizing their significance. While they may look like ordinary text files, RTFs (Rich Text Format) offer unique advantages—and some hidden security concerns.

In this article, we’ll break down what an RTF file is, why businesses still use it, its pros and cons, and how to handle it securely in today’s digital landscape.

What Is an RTF File?

An RTF (Rich Text Format) file is a document format developed by Microsoft in 1987. Unlike plain text (.txt), it allows formatting elements such as bold text, italics, fonts, colors, and images. The purpose of RTF was to create a universal file type that could be opened across different word processors and operating systems.

👉 In simple terms, an RTF file is a cross-platform document format that preserves basic text styling without depending on one specific software.

Why Do Businesses Use RTF Files?

Even though newer formats like .docx and .pdf dominate, RTF files are still relevant in business and IT because of their:

• Compatibility: RTF can be opened by almost any text editor, from Microsoft Word to Google Docs.

• Lightweight Design: Smaller file sizes compared to some rich media documents.

• Simplicity: Ideal for quick document transfers without formatting loss.

• Cross-Platform Functionality: Works across Windows, macOS, and Linux systems.

For IT managers and executives, RTF remains a reliable fallback option when sharing files with diverse stakeholders.

Benefits of RTF Files

Understanding what is an RTF file also means recognizing its advantages:

1. Universal Access: No need for special software.

2. Stable Formatting: Maintains fonts, lists, and styles.

3. Low File Size: Efficient for email and storage.

4. Long-Term Usability: Supported for decades, making it useful for archival.

Risks of RTF Files in Cybersecurity

While RTF files are convenient, they also pose security risks that business leaders should not ignore. Hackers have exploited vulnerabilities in RTF files to deliver malware, ransomware, or phishing payloads.

• Embedded Code Exploits: Some RTF files may contain malicious code targeting Microsoft Word or other applications.

• Social Engineering Attacks: Employees may open suspicious RTF attachments, thinking they’re harmless.

• Bypassing Filters: Because RTFs appear simple, they sometimes bypass basic email security filters.

📌 Security Tip: Always scan RTF attachments with advanced endpoint security tools before opening.

How to Open and View an RTF File

Most devices can open RTF files without extra software. Here’s how:

• Windows: Use Microsoft Word, WordPad, or Notepad.

• Mac: Open in TextEdit or Microsoft Word.

• Mobile Devices: Use apps like Google Docs, WPS Office, or Microsoft Word mobile.

• Linux: Access through LibreOffice or OpenOffice.

How to Convert an RTF File

Sometimes businesses prefer converting RTFs into more modern formats. You can:

1. Convert to PDF for secure sharing.

2. Convert to DOCX for editing in Microsoft Word.

3. Use online converters (with caution to avoid data leaks).

4. Save As in Microsoft Word to change formats instantly.

👉 Converting RTF files helps organizations integrate them into modern workflows.

Best Practices for Handling RTF Files in Business

If you’re a CEO, IT leader, or cybersecurity expert, here’s how to safely manage RTF files:

• Educate Employees: Train staff to avoid opening suspicious RTF attachments.

• Use Secure File-Sharing Tools: Instead of email attachments, share via encrypted platforms.

• Deploy Zero-Trust Security: Restrict document execution and verify all access.

By adopting these practices, businesses can balance convenience with security.
