About PDFLAB.si

PDFLAB.si is a free online platform providing fast, accessible web utilities for viewing, organizing, converting, and editing PDF documents.

Our Architecture

Most tools on PDFLAB.si run entirely inside your web browser using client-side JavaScript and HTML5 Canvas. Your documents remain in local memory and are never transmitted to foreign cloud servers. For heavy tasks requiring backend engines, jobs run in isolated, unprivileged sandboxes with immediate stream cleanup.
