Does HTML Live Preview cost anything or require an account?

No. HTML Live Preview is completely free with no usage caps, subscriptions, or sign-up forms — supported by unobtrusive ads, and usable for personal and commercial work alike.

Can I use HTML Live Preview on a phone or offline?

Yes. The layout adapts to phones and tablets, and because the logic ships as static client-side code, HTML Live Preview keeps working on intermittent connections once the page has loaded.

How does HTML Live Preview work without uploading my data?

HTML Live Preview runs entirely inside your browser's sandbox: the page loads once, and every operation after that executes on your own device's CPU. No input, file, or result is transmitted to any server — you can even watch the network tab stay silent while you use it.

Preview (sandboxed)

The preview runs in a sandboxed iframe: scripts execute, but the frame cannot touch this page, its cookies or your local storage. Perfect for testing snippets, email templates and small experiments. External resources (images, CDNs) load normally. Note that sandboxed storage APIs may throw — that's intentional isolation.

100% Private & In-Browser

Processed locally using client-side JavaScript. Your files and data never touch any server.

Instant & Unlimited

No registration, no waiting queues, and no limits on file conversions or generations.
