Legacy to Modern Viewer

Adobe’s new modern PDF viewer is a reimagining of the look and feel of PDF viewing on web, desktop, mobile, and PDF integrations. It introduces a new framework and workflows that better map to user mental models and enables a consistent user experience whether you are viewing a PDF in Adobe Acrobat or embedded on your website.

As of April 2023, the legacy viewer is no longer available. All requests to it will load the new modern PDF viewer. The documentation below will be useful for developers needing to migrate to the modern viewing experience.
