PSPDFKit – The leading framework for displaying and annotating PDFs on mobile.

PSPDF Instant

Seamless collaboration for PSPDFKit-powered apps

Deploying Instant on your servers and integrating it with your PSPDFKit-powered apps seamlessly enables real-time syncing of annotations and PDF documents.

With just a few lines of code, Instant gives your users a massive productivity boost.

How it works

The server backend

Instant’s server backend is delivered in a Docker container for easy integration with your existing infrastructure. The server takes care of syncing the annotations and PDF files without you having to worry about it.

The mobile and web frameworks

Enabling Instant is a simple matter of adding the framework to your PSPDFKit-powered app and pointing it at your server backend.

Available now for Web, in Beta for iOS and coming soon for Android.

What you get

Improved user experience

No longer do your users need to wait for every team member to incorporate their changes or worry about whether they are viewing the latest version. With changes being pushed in real-time, they will always have the most current version of a document at their fingertips.

Complete control over data

Hosting the server backend yourself means you always stay in complete control over your data and your users’ workflows.

Use cases


Integrating Instant for a classroom application turns the annotation features of our frameworks into presentation tools. Any annotations or changes made by the teacher appear instantly on every student’s device—a true interactive teaching tool.


Annotating on a large blueprint can be difficult, especially when changes need to be communicated quickly. Before Instant, you would need to annotate, save the PDF, upload the PDF, wait for it to be downloaded, annotated and then re-uploaded. Now with Instant, annotations are stored if you are offline and synced automatically when you come online.

Real-time collaboration

With minimal changes to your PSPDFKit-powered app, you can provide powerful real-time collaboration tools. Now with Instant, people and teams can invite others to work on the same document, in real-time.
