HTML Class Extractor: Find Classes and Usage Counts
HTML Class Extractor parses HTML and lists the class names it finds with a usage count, sorted by frequency. Paste or drop HTML to review which classes appear most often, then copy the values you need. Use the results to audit CSS coverage, inspect page markup, or gather class names for further review.
HTML Class Extractor is a browser-based tool for finding CSS class names in HTML. Paste or drop markup to see the class names it contains, along with a usage count for each. The results are sorted by frequency, making it easier to review common classes first and copy the values you need.
The tool parses the supplied HTML and extracts class names from its markup. It focuses on classes and their usage counts; it does not describe a conversion between HTML and CSS. HTML provides the page markup, while CSS uses selectors, including class selectors, to target elements for styling. Extracting the class names gives you a practical inventory of classes present in the HTML.
Developers can use that inventory when auditing CSS coverage, checking page markup before scraping, or preparing class names for a spreadsheet or team review. Frequency-sorted results help highlight which classes appear most often, while the copied values can support further investigation in your own workflow. The tool is useful when you want a quick view of class usage without writing a script.
HTML Class Extractor runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server; after the page has loaded, the tool also works offline. It is free to use, so developers and DevOps engineers can inspect HTML class usage without relying on a server-based processing step.
Step 1: Paste or drop your HTML into the input. Use page markup that contains class attributes.
Step 2: Run the extraction to parse the HTML and find its class names.
Step 3: Review the results, which show each class name with its usage count and are sorted by frequency.
Step 4: Copy the class names or values you need for an audit, review, or spreadsheet.
