PDFPageElement: file 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 file read-only property of the PDFPageElement interface returns the <pdf-file> element whose pages the <pdf-page> shows: the one of names, otherwise the closest <pdf-file> ancestor.

Value

A PDFFileElement, or null when the page has no file.

Examples

Reading the file name

A page knows its file, so it can tell you the file's name and page count once the file has loaded.

js
const page = document.querySelector("pdf-page");
page.addEventListener("load", () => {
  const { name, js } = page.file;
  console.log(`${name}: ${js.numPages} pages`); // "web.pdf: 4 pages"
});

Specifications

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