Add a Free PNG to WebP Converter to Your Website in 60 Seconds

You can add a working PNG to WebP converter to any website with a single line of HTML. No API key, no authentication, no usage limits, no server-side setup. The tool runs entirely in your visitor's browser — it adds zero load to your server and processes images without uploading them anywhere.

Copy-paste the embed code below into any page, and your visitors get a fully functional image converter right on your site.

The Embed Code — Copy and Paste

Add this single line to any HTML page:

<iframe src="https://wildandfreetools.com/converter-tools/png-to-webp/"
  width="100%" height="700" frameborder="0"
  style="border:1px solid #21262d; border-radius:8px;"
  allow="clipboard-write"></iframe>

That is it. The iframe loads the full PNG to WebP converter, including drag-and-drop upload, quality slider, batch support, and download buttons. Everything processes in the visitor's browser.

Responsive version (fills container width):

<div style="width:100%; max-width:800px; margin:0 auto;">
  <iframe src="https://wildandfreetools.com/converter-tools/png-to-webp/"
    width="100%" height="700" frameborder="0"
    style="border:1px solid #21262d; border-radius:8px;"
    allow="clipboard-write"></iframe>
</div>

Where This Embed Makes Sense

Embedding a converter on your site creates a sticky, useful page that earns bookmarks and backlinks. It works best on:

• Developer blogs. Write a post about image optimization, then embed the actual converter so readers can try it without leaving your page
• Photography and design sites. Give your audience a free tool alongside your portfolio or tutorials. "Here is how to optimize your photos — and here is the tool to do it"
• Web optimization guides. If you write about Core Web Vitals, PageSpeed, or site performance, embedding the converter turns your advice into action
• Agency resource pages. Agencies can offer free tools as a value-add for clients. "Use our free converter to optimize your images before uploading to the CMS"
• Documentation sites. If your platform recommends WebP images, embed the converter in your docs so users can convert before uploading

The key SEO benefit: pages with interactive tools have higher engagement metrics (time on page, return visits) than purely text-based content. A converter gives visitors a reason to stay and come back.

How to Embed on WordPress, Shopify, Webflow, and HTML

WordPress (Block Editor):

1. Add a Custom HTML block to your post or page
2. Paste the iframe code
3. Publish or update

WordPress (Classic Editor): Switch to the Text tab and paste the iframe code.

Shopify: Add the iframe to a Custom Liquid section on any page.

Webflow: Add an Embed element and paste the iframe code.

Squarespace: Add a Code Block and paste the iframe.

Static HTML: Paste the iframe anywhere in your HTML file.

The embed works on any platform that allows iframes. No JavaScript integration, no API calls, no backend setup. If your CMS strips iframes for security, check the platform's documentation for allowlisting external iframe sources.

No API Key, No Rate Limits, No Branding Requirements

The embed is genuinely free with no strings:

• No API key or authentication. The iframe loads a static page. There is no auth layer to configure
• No rate limits. Since processing happens in each visitor's browser, there is no server-side load to limit. A thousand visitors converting simultaneously would not cause any issues
• No branding requirements. The tool has its own branding inside the iframe, but you do not need to add attribution or badges on your page
• No tracking of your visitors. The embedded tool uses basic page analytics, but it does not track individual file conversions or collect any data about what your visitors upload
• Zero server load on your site. The iframe loads from our CDN. The image processing runs in the visitor's browser. Your server does zero work

Other embeddable tools: we have converters for PNG to JPG, JPG to WebP, image compression, and image resizing — all embeddable with the same iframe pattern.

Frequently Asked Questions

Can I embed the PNG to WebP converter on my website for free?

Yes. Copy the iframe code and paste it into any HTML page. No API key, no account, no fees, no usage limits. The tool runs in your visitor's browser, so it costs you nothing to serve.

Does the embedded converter upload visitor files?

No. The converter processes everything in the visitor's browser. Files are never sent to any server. This makes it safe for privacy-conscious audiences.

Will embedding slow down my website?

The iframe loads asynchronously and does not block your page from rendering. The tool itself is lightweight. The only impact is the iframe loading its own CSS and JavaScript, similar to embedding a YouTube video.

Can I customize the embedded converter?

The iframe loads the standard converter with its default styling. You can control the iframe dimensions (width, height) and add border styling. The converter inside the iframe cannot be restyled.
