The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

Start tags are parsed and attributes are removed by exact name, prefix, or allowlist while element names and text are serialized. Script, style, and text-node content are not treated as attributes.

  • Named removal is safer than stripping whole elements.
  • Allowlists support privacy cleanup.

Worked example

Sanitize pasted HTML content
Remove inline styles and event handlers from HTML copied from a webpage
Input
											<div style="color:red" onclick="alert(1)"><p style="font-size:14px">Hello</p></div>
Output
												<div><p>Hello</p></div>

When to use this

Scrapers, sanitizers, and migrations remove tracking or obsolete attributes.

Edge cases

  • onclick contains executable text and should be removed by exact name.
  • data-* may hold meaningful app state.
  • Boolean attribute presence is meaningful without a value.
