Preview
The preview runs in a sandboxed frame with no access to this page, so your code cannot touch anything outside it.
What this tool is for
Code on the left, the rendered page on the right, updating as you type. Useful for trying a layout, checking an email template, or explaining markup to someone without setting up a project first. The preview runs inside a sandboxed frame that has no access to this page, and nothing you write is uploaded anywhere.
How to use it
- Write or paste HTML, including style and script tags.
- Watch the preview update, or switch live mode off and press run when you prefer.
- Download the result as an .html file when it looks right.
Frequently asked questions
Do scripts run in the preview?
Yes, otherwise the editor would be lying to you. The frame is sandboxed without same-origin access, so code in the preview cannot read this page, its storage or anything else outside the frame.
Can I load external CSS or images?
Yes, if the address is reachable over https. Anything served over plain http will be blocked by the browser inside a secure page.
Is my code saved anywhere?
No. It exists in this tab only. Closing the page loses it, so download the file if it matters.
