HTML Viewer
Paste raw HTML and see it rendered immediately — useful for checking an email template or a fragment without saving a file first.
How to use it
- Paste the HTML you want to inspect.
- The rendered result appears alongside it instantly.
- Character, line and tag counts are shown underneath.
Paste raw HTML and see it rendered immediately, without saving anything to disk first — the case this covers is checking a fragment of markup you have received or copied from somewhere: an email template exported from a mail tool, a widget's embed code, a snippet a colleague sent over chat, or markup pulled from a page's source. It answers the “what does this actually look like” question in a couple of seconds.
Character, line and tag counts appear underneath the preview, which is a quick way to sanity-check pasted markup — an email template that suddenly has three times the expected tag count usually means something got duplicated or mangled in the copy.
What will and will not render
Inline styles and anything inside a <style> block render correctly, since that CSS travels with the markup itself. External stylesheets, and any image referenced by a relative path rather than a full URL, will not resolve — the viewer has no server-side context to fetch them from, so those parts of the layout will be missing from the preview even though the underlying markup is valid.
Questions people ask
Can I view a whole page including its CSS?
Yes, as long as the styles are inline or in a <style> block. External stylesheets and images referenced by relative path will not resolve.
Is anything uploaded?
No. Everything runs in your browser — no file, image or snippet you use here ever leaves your device.
