Embed our free tools on your website
Add any of our 34+ tools — and every unit converter — straight into your own pages. Copy a snippet, paste it where you want the tool, and you're done. It's free forever: no sign-up, no API key, no ads inside the widget. The only thing we ask is that you keep the small attribution link.
- 1. Pick a tool and copy its embed code below.
- 2. Paste the snippet into your page, post or template.
- 3. That's it — the tool works, and the visible link stays.

Embedding FAQ
Is embedding really free?
Yes — completely free, forever. No sign-up, no account, no API key and no usage limits. Paste the snippet and the tool works.
Do I have to keep the attribution link?
Yes. Each snippet includes a small visible "by Internet Tool Wizard" link next to the widget. Keeping that link is the only condition for using the embed — please don't remove or hide it.
Will the widget slow down my website?
No. The tool loads in a lazy-loaded iframe, so nothing downloads until a visitor scrolls it into view, and it runs in its own sandbox — it has no effect on your page's own load speed or scripts.
Does the embedded tool show ads or track my visitors?
No. Embedded widgets carry no advertising, no Google Analytics and no tracking cookies. Everything the tool does runs locally in the visitor's browser; nothing is uploaded.
Can I change the size of the widget?
Yes. The snippet uses width: 100% so it fits your column, and you can set any height. The widget also posts its content height to the parent window, so you can auto-size it with a tiny listener if you prefer.
Which tools can I embed?
Every standalone tool listed on this page, plus every unit converter on the site (length, area, land units, time, temperature, data and more) — over 700 converters in total. Open any converter and copy its embed snippet the same way.
