What is an RTF file?
The .RTF file extension stands for Rich Text Format File. It is a cross-platform document format developed by Microsoft. An .RTF file stores text and basic document formatting. Unlike a plain text file, it supports text styling like bolding, italics, different font sizes, and basic image embedding.
How to open RTF files?
You can open .RTF files with almost any modern word processor. Popular options include Microsoft Word, Apple TextEdit, LibreOffice Writer, and Google Docs. Because the underlying file is encoded in plain text using special markup tags, developers can also inspect the raw code using code editors like Notepad++ or Visual Studio Code.
Best practices and troubleshooting
Sometimes a file named .RTF is actually an Office Open XML document (.DOCX) that was incorrectly renamed, or a compressed file containing other data. viewer.online/rtf analyzes .RTF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If you need to share the document with users who expect standard modern formats, you should convert it. You can convert .RTF files to .PDF, .DOCX, or .TXT on convert.guru.
Summary
viewer.online/rtf directly opens and previews .RTF files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
