WebViewer is a powerful JavaScript-based PDF Library that's part of the PDFTron PDF SDK. It allows you to view and annotate PDF files on your web app with a fully customizable UI.

This is a WebViewer sample to show how you can save and load annotations through files with PHP backend.

Before you begin, make sure your development environment includes Node.js and a PHP development environment such as built-in CLI, XAMPP or AMPPS.

git clone https://github.com/PDFTron/webviewer-annotations-php-sample.git
cd webviewer-annotations-php-sample
npm install

Serve the root directory of this project using the PHP development environment, and navigate to /client/index.html.

• Create annotations with annotations tools in the header
• Save annotations with the save button in the header
• Load annotations by refreshing the app
• You can find annotation data saved into an XFDF file in server/xfdf folder
