Document security in our JavaScript PDF viewer

Nutrient Web SDK offers developers control over document security when PDF, Word, Excel, PowerPoint, or image files are displayed in the viewer.

Quick start

Open a password-protected PDF document:

NutrientViewer.load({
  container: "#pspdfkit",
  document: "/path/to/protected.pdf",
  password: "user-password"
})
  .then((instance) => {
    console.log("Protected document opened");
  })
  .catch((error) => {
    if (error.message.includes("password")) {
      console.error("Invalid password");
    } else {
      console.error("Failed to open:", error.message);
    }
  });
