How to Use​

  1. Copy HTML Source: Use your browser's "View Page Source" feature to copy the entire HTML code of the page you want to inspect.
  2. Paste and Extract: Paste the HTML into the text field and click "Analyze".
  3. Check Results: Browse the extracted information organized into "Preview", "Basic Meta", "OGP & SNS", and "JSON Data" tabs. You can easily copy individual values or export the full data as a JSON file.

💡 Key Validation Features​

  • Character Count Indicators: Automatically evaluates whether your Title (recommended: 50–60 characters) and Meta Description (recommended: 80–120 characters) are optimized for search engines with a visual progress bar.
  • Search Engine & Social Media Preview:
    • Google Search Preview: Mimics how your page will look on Google search results pages.
    • Social Share Preview: Replicates the card style (with the OGP image) when shared on Facebook, Slack, Twitter, etc.
🔒 100% Safe Local Processing

All HTML source code parsing is executed strictly inside your browser (client-side). None of your source code or page data is sent to external servers. It is 100% safe to use even for highly confidential internal staging pages, development mockups, or pages containing private data.
