HTMLRadar · Free tool

Turn an HTML file into a link you can share.

Updated August 2026

Drop your HTML file on this page. It previews in your browser, then you sign in and HTMLRadar gives you a link you can send anyone. The link shows who opened it, which sections they read, and for how long. Free for two tracked links, then $15 a month. Open source.

Drop an HTML file, or click to browseSingle-file .html or .htm, up to 30 MB. The file is not uploaded to HTMLRadar until you sign in.

How it works, in three steps

  1. Drop the .html or .htm file above. Your browser renders the preview, so you can check it looks right before anyone else sees it.
  2. Press “Get your tracked link” and sign in. That is the moment the file is uploaded — never before.
  3. Create a share link on the document page and send it. You can add an email gate, a password, or an expiry date to any link.

What you get with the link

A plain URL tells you nothing about the reader. A tracked link tells you who opened it, which sections they read, and how long they spent on each one. You can give each recipient their own link, so you know which of them read the pricing section and which stopped at the first page.

Every link can carry an optional email gate, a password, and an expiry date. Revoke it and the link stops working.

Why not just host the file somewhere?

You can. Dropbox, S3, GitHub Pages, or your own server will all serve an HTML file at a URL, and if all you need is a public page, host it there. HTMLRadar answers a different question: whether the person you sent it to actually read it, which sections they read, and for how long. Each recipient gets their own link, so the answer is per person.

Already hosting the page yourself? You can paste that URL into HTMLRadar instead of uploading a file, and track the page where it lives.

Common questions

How do I share an HTML file as a link?
Drop the file on this page, sign in, and HTMLRadar hosts it behind a tracked link you can send by email or chat. The recipient opens a normal web page, with no account on their side.
Is this HTML to link converter free?
The first 2 tracked links are free, with no credit card. Unlimited links are $15 a month or $150 a year. HTMLRadar is also open source under AGPL-3.0, so you can run the whole thing yourself instead.
Does my file get uploaded before I sign in?
The file itself is never uploaded to HTMLRadar until you sign in: the preview is rendered by your own browser, and the file is held in your browser storage across the sign-in. If the HTML references images, fonts or stylesheets on other websites, your browser fetches those to render the preview, exactly as it would on any web page. Scripts, forms and navigation are blocked in the preview.
