Frequently asked questions
What does HTML Viewer do?
Render any HTML source in a sandboxed preview. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is HTML Viewer free to use?
Yes. HTML Viewer is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open HTML Viewer, do the job, and take the result — nothing is gated behind a signup form.
Is the code I paste in sent to a server?
No. HTML Viewer runs entirely inside your browser tab, so the code you paste stays on your own device. Nothing is uploaded, which means there is no copy of it on a server to worry about.
Does HTML Viewer work on Mac, Windows, and phones?
Yes. HTML Viewer runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
Yes. There is no queue, no per-hour quota, and no counter that runs out — run HTML Viewer as often as the work needs.
