Enter any URL, or drag a file in to preview it.
Some sites block being shown in frames (their X-Frame-Options / CSP) —
leave Proxy on (top bar) to view them anyway; it re-serves the page from this origin.
Login-gated pages show their login screen (cookies don't carry through), which is
expected for a visual check — turn Proxy off, or use ↗ Open tab, for the real session.
Local file:// paths only work when you open this tool from your own machine
— the public version can't reach your disk, and a dragged file previews as a blob (its
relative assets may not load).
