As a Master Mariner with 28+ years at sea, I constantly dealt with large PDF files— manuals, certificates, cargo documents—that needed to be emailed over expensive satellite connections.
Online compression tools weren't an option: uploading sensitive documents to random servers was a cybersecurity risk, and internet at sea is unreliable anyway.
So I built PDFCompress—an offline-first tool that works exactly when and where you need it, without compromising your privacy.
