Embed and run the editor

Everything needed to put the PDF editor in your product — hosted with the SDK, or self-hosted in your own infrastructure.

Getting started

Install the SDK, embed the editor and add your first document.

Configuration

Every option the editor accepts - title, icon, hidden controls, injected buttons, provenance and licence.

API reference

The class, the React component and every method, event and type.

Page provenance

Every page carries where it came from - by default its file name and page number, or your own JSON.

Licensing

Test mode, the licence JWT, what is checked and how to get one.

Self-hosting

Run the editor container in your own infrastructure — for air-gapped networks, data residency and strict change control.

Security and data handling

Documents are processed in the browser. Nothing is uploaded, and there is no server-side PDF processing.

Without the SDK

The bare iframe and the postMessage protocol, if you want to wire the editor yourself.

RSJ PDF Merge SDK

Embed PDF merging, sorting and splitting in your own product — or self-host it in your infrastructure.
