About Headings Extractor Extract H1 to H6 from URL or HTML File

The Headings Extractor is a simple and effective tool that allows you to extract all HTML heading tags (H1 to H6) from a webpage URL or an uploaded HTML file. It scans the HTML content, identifies heading elements, and presents them in a structured and readable format along with useful summary information.

This tool is helpful for analyzing page structure, reviewing heading usage, and understanding how headings are organized within an HTML document.

What Is This Tool?

This tool is designed to extract and analyze HTML heading tags (H1, H2, H3, H4, H5, H6) from a given source.
The source can be either:

  • A live website URL

  • A local .html file uploaded by the user

After processing, the tool displays all detected headings along with their level, position, and contextual hierarchy.

What Are HTML Headings (H1–H6)?

HTML headings are structural elements used to define headings and subheadings on a webpage.

  • H1 represents the main heading

  • H2–H6 represent sub-sections with decreasing importance

Headings help organize content and define the structure of an HTML document, making it easier to read and understand.

Frequently Asked Questions

Find answers to common questions about this tool

If you enter a URL without a scheme (for example: example.com), the tool automatically adds https:// before processing it. This ensures the request can be made correctly.

The tool only accepts files with a .html extension or files with text/html type. If you upload any other file type, it will be rejected with an error message.

Uploaded HTML files must be UTF-8 encoded. If the file uses a different encoding and cannot be decoded properly, the tool will display a decoding error.

The position value represents the order of that heading within its own level.

For example:

  • The first <h2> on the page will have position 1

  • The second <h2> will have position 2

Positions are counted separately for each heading level.

The tool walks up the DOM tree from the current heading and checks parent elements.
If parent headings exist, they are included in the hierarchy (up to three levels).

This context helps identify where a heading appears within the page structure.

If the HTML content does not contain any H1–H6 tags, the tool returns a message indicating that no headings were found.
