How to use HTML Viewer
Paste HTML into the editor to inspect the formatted source and preview the rendered markup in the isolated output area.
What the tool does
Paste HTML markup to inspect and preview its rendered structure in a focused browser workspace.
Supported inputs
The code, JSON, expression or encoded text requested by the editor, using a fabricated or redacted sample rather than a live secret.
Actual output
An interactive result or saved workspace with only the actions relevant to its current state.
Privacy and processing
Processing runs locally unless the tool clearly requests a public network resource.
Limitations
Browser rendering can differ from a complete website because external styles, scripts, assets and server-side behaviour may not be available.
Common mistakes
Check that the selected input type, units and output format match the task. Do not discard the source before opening the result, and do not treat a preview, estimate or converted file as verified until you have reviewed it.
