What is an HTML file?

HyperText Markup Language

Developed By
W3C / WHATWG
Initial Release
1993
MIME Type
text/html

HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser, defined by the World Wide Web Consortium (W3C) and the WHATWG Living Standard. An HTML file consists of plain text tags that structure content into a Document Object Model (DOM), enabling the embedding of scripts (JavaScript), cascading style sheets (CSS), and multimedia. The format has evolved from SGML-based roots to the current HTML5 specification, which includes semantic elements and APIs for complex web applications.

How to open an HTML file

Operating systems universally support HTML rendering via pre-installed web browsers like Microsoft Edge (Windows), Safari (macOS), or Firefox (Linux). For source code modification, developers utilize specialized editors such as Visual Studio Code, IntelliJ IDEA, or Notepad++. No proprietary software is required, as the format is an open, non-proprietary standard text file.

What is a DOC file?

Microsoft Word Binary File

Developed By
Microsoft
Initial Release
1983
MIME Type
application/msword

The DOC extension refers to the proprietary binary file format used by Microsoft Word versions 97 through 2003. It is structured around the Object Linking and Embedding (OLE) Compound File Binary (CFB) format, acting as a file system within a file that manages streams and storages for text, formatting, scripts, and metadata. Unlike modern XML-based alternatives, DOC files store data in binary records, which can make parsing complex and prone to corruption if the binary headers are damaged.

How to open a DOC file

Microsoft Word remains the primary software for full-feature support of the DOC binary format. However, owing to its ubiquity, most third-party word processors including LibreOffice Writer, Apache OpenOffice, and Corel WordPerfect provide reverse-engineered support for opening and editing these files. Google Docs also offers import capabilities, though complex formatting utilizing legacy OLE objects may experience rendering shifts during conversion.
