Want to add an image compressor, JSON formatter, or QR code generator to your website without building it from scratch? With WebToolsz's free embed feature, you can add 30+ fully functional web tools to any page using a single line of iframe code. No API keys, no server setup, no monthly fees.
Whether you run a blog, a developer portfolio, an educational site, or a SaaS dashboard — embedding tools adds instant value for your visitors and keeps them on your site longer.
What Is the WebToolsz Embed Feature?
The embed feature lets you place any WebToolsz tool inside an <iframe> on your own website. The embedded tool looks clean and minimal — just the tool interface with a small "Powered by WebToolsz" footer. Your visitors can use the tool directly on your page without navigating away.
Key benefits:
- Zero cost — completely free, no usage limits
- No API key or account — just copy the iframe code
- Privacy-first — all tools run in the visitor's browser, files never leave their device
- Responsive — works on desktop, tablet, and mobile
- Lazy loading — doesn't impact your page speed or Core Web Vitals
- Sandboxed — runs in an isolated iframe, won't interfere with your site's code
How to Embed a Tool — Step by Step
Scroll down past the tool interface and click the green Embed this Tool button (visible on all embeddable tools).
Select from 4 size options: Default (100% × 640px), Compact (100% × 480px), Fixed (800 × 620px), or Mobile (480 × 700px).
Click "Copy Code" — the generated code is ready to paste into your HTML.
Add the iframe code anywhere in your HTML — a blog post, a sidebar, a dedicated tools page, or even inside a CMS like WordPress.
Example Embed Code
Here's what the embed code looks like for the Image Compressor:
<iframe
src="https://webtoolsz.com/embed/image-compressor"
width="100%"
height="640"
frameborder="0"
style="border:none; border-radius:12px; box-shadow:0 4px 24px rgba(0,0,0,0.12);"
title="Image Compressor — WebToolsz Widget"
loading="lazy"
sandbox="allow-scripts allow-same-origin allow-forms allow-popups"
></iframe>loading="lazy" to ensure the iframe only loads when the user scrolls to it. This keeps your page fast and your Lighthouse score high. The sandbox attribute ensures the embedded tool runs in a secure, isolated environment.

Use Cases — Who Should Embed Tools?
Bloggers & Content Creators
Add an image compressor or word counter directly in your blog posts. Readers can use the tool without leaving your page, increasing time-on-site and reducing bounce rate.
Developer Portfolios & Documentation Sites
Embed a JSON formatter, Base64 encoder, or JWT decoder in your documentation. Developers love having tools right where they need them.
Educational Websites
Add a scientific calculator, unit converter, or typing test to your learning platform. Students can practice without switching tabs.
WordPress & CMS Sites
Paste the iframe code into any WordPress post, page, or widget using the HTML block. Works with Elementor, Divi, Gutenberg, and any page builder that supports custom HTML.
Privacy & Security
Embedded WebToolsz tools are designed with privacy and security as a priority:
- No file uploads — all processing happens in the visitor's browser using JavaScript APIs
- Sandboxed iframe — the
sandboxattribute restricts what the embedded page can do - No tracking of your visitors — we don't collect data from embedded tool usage
- No cookies injected — the embed page doesn't set cookies on your visitors' browsers
sandbox="allow-scripts allow-same-origin allow-forms allow-popups" attribute ensures the iframe can run tools but cannot access your page's DOM, cookies, or localStorage. Your site remains fully isolated.
Customization Tips
- Custom width/height: Change the
widthandheightattributes to any value (px or %) - Remove border radius: Set
border-radius: 0in the style for a flush look - Add a container: Wrap the iframe in a
<div>withmax-widthto control layout - Dark backgrounds: The tool auto-adapts if the user's system preference is dark mode

Try Embedding a ToolFrequently Asked Questions
Is embedding WebToolsz tools really free?
Yes, completely free. No API key, no sign-up, no usage limits. The tools run entirely in your visitor's browser, so there's no server cost on our end. The only requirement is keeping the "Powered by WebToolsz" attribution link visible in the widget footer.
Do embedded tools upload user files to a server?
No. All WebToolsz tools run 100% client-side in the browser. When your visitors use an embedded tool (like Image Compressor or Word to PDF), their files are processed locally on their device and never uploaded to any server.
Can I customize the size of the embedded tool?
Yes. The embed code uses a standard iframe that you can resize by changing the width and height attributes. WebToolsz provides 4 preset sizes: Default (100% × 640px), Compact (100% × 480px), Fixed (800 × 620px), and Mobile (480 × 700px). You can also set custom dimensions.
Which tools are available for embedding?
Over 30 tools are available including Image Compressor, Image Resizer, JSON Formatter, Password Generator, QR Code Generator, Base64 Encoder, Word Counter, Unit Converter, Hash Generator, Diff Checker, Scientific Calculator, Video Compressor, Word/Excel to PDF, and many more.
Will embedding slow down my website?
No. The iframe uses loading="lazy" so it only loads when the user scrolls to it. Since the tool runs in a sandboxed iframe, it doesn't affect your page's JavaScript or CSS. Your Core Web Vitals won't be impacted.
Can I remove the "Powered by WebToolsz" link?
No. The attribution link is required under our terms of use. It's a small, non-intrusive footer that says "Powered by WebToolsz". If the link is hidden or removed, the embedded tool will stop working and display an attribution required message.
Does it work with WordPress?
Yes. Simply paste the iframe code into a Custom HTML block in the WordPress editor (Gutenberg). It also works with page builders like Elementor, Divi, and Beaver Builder. No plugin required.
