Paste HTML.
See it rendered.
A clean, sandboxed HTML viewer. Paste any markup — email templates, landing page snippets, README exports — and watch it render live as you type. No upload, no signup, no nonsense.
The preview iframe is sandboxed — scripts are disabled, the page can't reach back into Linkos. We never send your HTML to our servers from this page.
Under the hood
How it works.
Paste HTML
Editor on the left accepts any HTML — fragment or full document. Drafts persist on your device.
Live preview
Sandboxed iframe renders your HTML safely on the right. Scripts are disabled by default.
Open full
Need to test outside the sandbox? "Open full" pops the HTML into a real new tab — scripts, anchors, and devtools all work.
