FAQ

Can I viewer HTML directly in browser?

Yes. The HTML route runs in browser so you can inspect the result without sending the document to a server.

Does this HTML route keep the result copy-ready?

Yes. The shared workspace keeps the processed result visible so you can review and copy it immediately after running the tool.

What to expect on this route

Use HTML Viewer when you need a fast read-only rendered inspection pass before copying, debugging, or moving the markup into another workflow.

When to use this viewer

  • Inspect rendered HTML snippets without editing the source markup first.
  • Verify headings, links, lists, and layout structure before reusing or documenting the fragment.
  • Open a preview-ready result quickly before handing the markup to formatter or validator routes.

Accepted HTML input

  • Paste valid HTML documents or fragments directly into the editor.
  • Rendered preview and normalized markup stay visible together for easier inspection.
  • Broken closing tags or malformed structure trigger validation feedback instead of viewer output.

What the result shows

  • The preview shows how the markup renders while the paired output keeps the normalized HTML copy-ready.
  • Viewer output is read-only, which keeps the route focused on inspection rather than mutation.
  • Fullscreen preview makes larger snippets easier to inspect without leaving the route.

Common HTML issues

  • Mismatched closing tags and partially copied fragments are common reasons the preview fails.
  • If the rendered result looks incomplete, recheck whether key wrapper elements or styles were omitted from the sample.
  • If you need to fix the markup directly, switch to HTML Editor instead of continuing in the viewer.
