PDFPageElement: anno 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 anno read-only property of the PDFPageElement interface returns the annotation layer of a <pdf-page>: the links and form fields drawn over its image.

Value

A PDFPageAnnoLayer object with sync().

const page = document.querySelector("pdf-page");
page.file.formData = { "12R": { value: "Ada" } };
page.anno.sync(); // the field shows "Ada"
