What is the HTML Preview?
Testing HTML usually means creating a file and opening it. This tool encodes your snippet into a self-contained data URI — click the generated link and your HTML renders in a new tab exactly as a browser would show it, scripts free. Perfect for testing email templates, SVGs, and layout experiments.
Frequently Asked Questions (FAQ)
Q: Does the preview run JavaScript?
No — data URIs render static HTML/CSS only, which also makes the preview safe to open. For JS testing use your browser's console.
