About HTML Preview
HTML Preview renders your HTML code as-is inside a sandboxed iframe so you can see its visual result. To see the colored source code instead, use HTML Source Viewer.
The sandbox disables scripts and same-origin access for safety — the preview is safe even for HTML from unknown sources.
FAQ
Is my file/data uploaded to a server?
No. Everything is opened and rendered in your browser with JavaScript (the File API). Nothing is uploaded, logged, or stored on our servers — safe for sensitive files.
How is this viewer different from an extractor or parser?
A viewer shows the content as-is (read-only) — you see the file/text the way it is. An extractor pulls raw data (e.g. text from a PDF) into a string, while a parser breaks input into its component structure. A viewer focuses on "see", not "transform" or "pull".
