PDF security API

Protect sensitive PDF documents with a secure PDF API for enterprise workflows. Add password protection, disable printing, restrict copying, and apply access controls for secure document delivery, regulated workflows, and enterprise document handling.

Custom document protection

Add passwords, disable printing, and restrict copying so only authorized users can access or interact with protected PDFs.

Enterprise-ready security workflows

Use PDF permissions and password protection as part of a broader DWS platform with security, privacy, and SOC 2 Type 2 trust context for commercial evaluations.

Simple and transparent pricing

Select a package that suits your needs according to the number of credits you wish to spend. Each API tool and action has a specific credit cost.
