What is index.html?

Last Updated : 31 Jan, 2025

In web development, index.html is the standard filename for a website's homepage. When users visit a website without specifying a particular page, the server automatically delivers the index.html file, ensuring a consistent and organized entry point for visitors.

Default Homepage: Acts as the entry point for website visitors.
Server Recognition: Web servers prioritize index.html when no specific page is requested.
Organizational Standard: Maintains consistency across web projects.

Here's a basic example of an index file in HTML:

HTML

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>My Website</title>
</head>
<body>
    <h1>Welcome to My Website</h1>
    <p>This is the homepage.</p>
</body>
</html>

Understanding the Role of index.html in Web Development

The index.html file serves as the default landing page for websites, playing a crucial role in site architecture and user experience.

Site Architecture: Placing an index.html file in each directory ensures that users are presented with a default page when accessing a directory, enhancing navigation and usability.
Security Feature: Having an index.html file prevents the web server from displaying a list of files in a directory, thereby protecting sensitive information from unauthorized access.
Alternative File Types: Some websites utilize different default file types, such as index.php or index.asp, depending on the technologies and server configurations in use.

Web servers often look for specific default page names when a user accesses a directory without specifying a file. While index.html is the most common, other default filenames include:
