Frequently asked questions

Will transparency be preserved?
PDF doesn't support page-level transparency — we composite onto a white background.
Are my files uploaded?
No. Everything happens in your browser.
Can I pick the page size?
Yes — A4, Letter, or fit-to-image.
Image too big?
We process large files in a Web Worker so the page stays responsive.
Can I combine PNG and JPG?
Yes, drop both in and we'll combine them in the order you set.

Embed this tool

Let your visitors use PNG to PDF without leaving your site. Paste the snippet below into any HTML page. Files stay private — everything runs in the visitor's browser.

<iframe
  src="https://pdfwox.com/embed/png-to-pdf"
  width="100%"
  height="600"
  style="border:none;border-radius:8px"
  title="png-to-pdf tool"
  allow="downloads"
  loading="lazy"
></iframe>
<script>
window.addEventListener('message',function(e){
  if(e.data&&e.data.type==='privpdf-resize'){
    var f=document.querySelector('iframe[src="https://pdfwox.com/embed/png-to-pdf"]');
    if(f)f.style.height=e.data.height+'px';
  }
});
</script>

The embed runs entirely in the visitor's browser — no files are uploaded. The iframe resizes automatically to fit its content via postMessage.
