How to use Static HTML ID Namespace Rewriter

Prepare a self-contained static HTML fragment for reuse by changing its identifiers and known IDREF attributes together. Source locations preserve comments, formatting and unrelated attributes; the result is a plain-text source download.

  1. Enter input, id prefix.
  2. Choose the settings for static html id namespace rewriter, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 100,000 markup characters, 20,000 nodes, 60 levels and unique simple ASCII IDs of 1–100 characters. Prefixes use up to 30 simple ASCII characters.
  • Rejects templates, foreign SVG/MathML, scripts, styles and event/style attributes. Known IDREF attributes and exact # fragments only; arbitrary data attributes, CSS/JS references and legacy named anchors are outside scope.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Is the rewritten source rendered in this page?

No. It remains text in the result and download. Inspect unresolved references and validate the fragment in its intended application before using it.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
