HTML Preview Online
An HTML preview takes the code you are writing and shows the rendered page in real time, right next to the editor.
When you are tweaking a hero section or testing a media query, opening a file in a separate browser to check every change wastes the entire feedback loop, so our HTML Preview puts the live render in the same window.
How AIFreeForever's HTML Preview Works
- Paste your HTML into the left editor or drop an
.htmlfile onto the panel. - Watch the iframe on the right render the page in under half a second.
- Switch the device bar to tablet or mobile to test responsive breakpoints.
- Use Screenshot, Print, or Fullscreen to export or view the page at full width.

Made for Frontend Designers, Email Coders, and QA Engineers
When a hero section reflows the wrong way on mobile, frontend designers open the HTML Preview to flip between viewport widths until the breakpoint behaves. Email coders use the same workspace to confirm a marketing template renders correctly before pushing it through a delivery platform, and QA engineers run print preview to verify @media print styles before signing off on a release.
The Most Flexible Way to Render HTML
Although the most flexible way to test a page across devices means spinning up a local server and opening every viewport by hand, our HTML Preview gives you desktop, tablet, mobile, print, and fullscreen views in one window.
Sandboxed Iframe
The preview runs inside a sandbox so risky scripts cannot reach your data.
Multiple Viewports
Desktop, tablet, and mobile widths share the same code without a reload.
Browser-Only Processing
FileReader handles uploads locally, so HTML never leaves the tab.
