How to use the HTML Editor & Viewer

1. Write or paste your HTML

Type directly into the left code panel or paste the markup you already have: a contact form, an email template, a complete HTML page, with CSS and JavaScript or any HTML project. Syntax highlighting helps you see tags, attributes and values clearly as you work.

2. Or upload a file

If you already have an .html file, drag and drop it onto the code panel or click "Upload file" to choose one from your device. It will load directly into the editor.

3. Watch the live preview

The right panel shows a live preview. It renders your HTML as you type in time. Switch to "Source" whenever you want to see the markup being rendered.

4. Edit either side

Use the toolbar above the code panel to insert tags, format text or undo and redo changes.. Click directly into the preview and type. When you select text a formatting toolbar appears (italic underline, links, alignment, color). Clicking an image or another element allows you to delete it once. Both panels stay in sync at all times.

5. Copy or download HTML

When you have finished editing and the HTML viewer shows the result you need click "Copy HTML" to copy the source to your clipboard or click "Download .html" to save it as a file.

Privacy & Secure

Nothing you type or upload is ever sent to a server. Your work stays stored in your own browser so you will not lose it and nothing is tracked.
