Case Study: Zelená Pošta reduces postage costs 60% and accelerates PDF processing with Foxit Software's Quick PDF Library

How Zelená Pošta Uses Quick Pdf Library

Zelená Pošta is a Slovakian hybrid‑mail service that lets customers send letters as PDFs to be printed, enveloped and mailed on their behalf — and receive paper mail as email when senders join the network — eliminating queues and stationery hassles. Their challenge was to build a maintainable, high‑performance PDF processing pipeline (splitting, merging, printing, signing) that could handle very large source documents without bottlenecks.

They implemented Quick PDF Library 13 in a C++ process invoked from a node‑webkit app, using the LIB distribution for easier maintenance. The result: postage costs fell by more than 60% versus traditional methods, PDF processing of 1,000+ page sources ran about 60% faster (test case finished in ~50 seconds), and the company gained a greener, faster workflow with ongoing SDK improvements.
