Frequently Asked Questions

How does client-side PDF processing work?

Normally, tools upload files to remote servers, process them, and download them back. Oltag-PDF loads open-source JavaScript packages (like pdf-lib and pdf.js) directly inside your browser. The file is processed using your CPU threads locally, and compiled into a downloadable Blob immediately.

Are my documents safe with Oltag-PDF?

Yes, they are safer than on any other platform. Because files never leave your local computer, third parties can never inspect, copy, or save your confidential data.

Do I need to install any plugins or software?

No, Oltag-PDF runs inside any standard browser (Chrome, Firefox, Safari, Edge) on both desktop computers and mobile devices.
