Frequently asked questions
Do scripts run in the preview?
No. Scripts and forms are disabled, and nothing can load from other sites, so pasted code can't do anything harmful.
Why don't my images or web fonts show?
External files are blocked so the preview never contacts other sites. Use data URIs to include images.
Is what I paste sent anywhere?
No. The tool runs entirely in your browser and never sends what you type or paste to a server.
Is it free?
Yes. It's free, with no sign-up and no limits.
