Code samples for PDF Optimizer
Product update
The PDF Optimizer has been replaced by the Pdftools SDK.
See the Migrate from the PDF Optimizer to the Pdftools SDK documentation.
PDF Optimizer lets you compress and optimize PDFs for the web, printing, and long-term archiving. Here are some examples of how to integrate the code in your development.
