PDFFileElement: URL property

Works in all major browsers
Since July 2026

WebPDF works in Chrome and Edge 125, Firefox 153 and Safari 18, on desktop and mobile, and in every later version: the oldest versions its PDF.js build supports, which already have every platform feature WebPDF needs. Since July 2026, that is every major browser.

The URL property of the PDFFileElement interface sets or returns the URL of the PDF a <pdf-file> loads, as a URL object.

Value

A URL: src resolved against the document's base URL. The setter only takes a URL object and throws a TypeError for anything else.

Examples

Reading the host of a file

js
const file = document.querySelector("pdf-file");
console.log(file.URL.host); // "pdf.ist"
file.URL = new URL("forms.pdf", location.href);

Specifications

Not part of any specification. <pdf-file> and <pdf-page> are autonomous custom elements defined by WebPDF.pro.
