iframe form builder

If you specifically want an iframe — no loader script, no external JavaScript, nothing that touches the rest of the page — this is the shape of embed that does it.

Why the usual setup falls over

  • Script embeds run on every page load even when the form is never seen.
  • Hard-coded iframe heights create nested scrollbars.
  • Sandboxed environments and strict content-security policies block third-party scripts outright.

What you get

  • Script-free markup

    The generated snippet is an iframe plus a wrapper div. Nothing else.

  • Aspect-ratio sizing

    The wrapper keeps the form proportional instead of guessing a pixel height.

  • CSP friendly

    One frame source to allow, no inline scripts to whitelist.

  • Works with any form URL

    The generator accepts LemForms, Typeform, Tally, Jotform, Google Forms and Paperform URLs.

  • Prefill by URL

    Hidden fields can be populated from query parameters on the iframe URL.

How it runs

  1. Paste a form URL into the embed generator.

  2. Choose the responsive iframe variant.

  3. Copy the snippet into your page.

  4. Allow the frame source in your content-security policy if you have one.

Frequently asked questions

Is the snippet really script-free?

Yes. The responsive variant is an iframe inside a CSS aspect-ratio wrapper.

Can I set the height manually?

Yes — the inline iframe variant takes a fixed height if you prefer one.

Can I prefill fields through the iframe?

Yes. Append query parameters to the form URL and map them to hidden fields.

Does it work inside another CMS or intranet?

Anywhere HTML is allowed and the frame source is permitted.
