How to use the HTML Editor

1. Write or paste your HTML

Type directly into the code panel on the left, or paste in markup you already have: a contact form, an email template, a full HTML page with CSS and JavaScript, or any HTML project. Syntax highlighting makes tags, attributes, and values easy to tell apart as you go.

2. Or upload a file

Already have an .html file? Drag and drop it onto the code panel, or click "Upload file" to pick one from your device. It will load straight into the editor.

3. Watch the live preview

The right panel is a live preview: it renders your HTML as you type, in real time. Toggle to "Source" any time to see the exact markup being rendered.

4. Edit either side

Use the toolbar above the code panel to insert common tags, format text, or undo/redo changes. Or click straight into the preview and type: selecting text brings up a matching formatting toolbar (bold, italic, underline, links, alignment, color), and clicking an image or other element lets you remove it directly. Both panels stay fully synchronized at all times.

5. Copy or download HTML

Once you've finished editing and the HTML viewer shows the result you need, click "Copy HTML" to copy the full source to your clipboard, or "Download .html" to save it as a file.

Your HTML stays private

Nothing you type or upload is ever sent to a server. Your work is only saved locally in your own browser, so you don't lose it, and nothing is tracked.
