What HTML comments does

HTML comments is a straightforward utility that takes any plain text input and wraps it in the standard HTML comment syntax (<!-- ... -->). It produces clean, valid comment code that can be inserted directly into source files to add notes, explanations, or temporarily hide sections without affecting how the page renders in a browser. The result is pure markup ready for copy‑and‑paste into any HTML document.

Questions

HTML comments FAQ

Can I use this tool to comment out entire HTML sections?
Yes, selecting 'Multiple line comments' allows you to wrap blocks of code or text in comment tags, effectively hiding them from browser display.
Does the tool support nested comments?
No, HTML does not support nested comments; the generator wraps the input in a single pair of <!-- --> markers.
Will the commented text appear on the rendered webpage?
No, content placed inside <!-- --> tags is ignored by browsers and will not be visible on the final page.
Is there a limit to how much text I can comment out?
The tool does not specify a character limit, but very long inputs may wrap or truncate in the display; for best results, keep comments concise.
