How to embed a tool

Pick a tool. Choose the calculator or converter you want from the dropdown above.
Set the size. Leave the width at 100% to fill its container, or set an exact pixel width. Adjust the height to fit the tool.
Copy the code. Click “Copy code” to grab the <iframe> snippet.
Paste it in. Drop it into any HTML block on your site — WordPress (Custom HTML block), Wix, Squarespace, Webflow, or a hand-coded page.

Is it free?

Yes — embedding our tools is completely free. Each embed includes a small “Powered by Super Simple Digital Tools” link back to the full tool. The tool runs in your visitor’s browser, loads on demand, and is maintained by us, so it stays current with no work on your side.
