HTML Viewer
Content updated .
Paste an HTML document or fragment and render it in an isolated preview without changing the current page.
How to use it
Paste code or open an HTML file, then select View HTML. Load sample demonstrates headings, lists and inline styles. Enable Live for automatic updates. New clears the document and preview.
Useful example
A copied email template or generated HTML fragment can be checked visually before you place it in a website or content system.
Inspect a fragment without uploading a file
Paste a fragment such as <ul><li>Draft</li><li>Review</li></ul> and choose View HTML. You do not need a complete document wrapper to inspect simple markup. Use the editor when your next task is repeated editing.
Frequently asked questions
Why are some images missing?
Remote content is blocked in the preview. Embedded data images are supported, but relative image paths cannot read adjacent files from your computer. Opening one HTML file does not upload its folder.
Can this test an email template?
It can inspect basic markup and inline styles. It does not reproduce Gmail, Outlook or other email clients, so it is not a cross-client compatibility test.
Does downloading include the preview restrictions?
Download preserves your original HTML source rather than the restricted preview wrapper. Review that source before opening it outside this sandbox.
