Deep Dive: Switching from iLovePDF Premium to Stirling PDF
Trade-offs, installation & data architecture
What you trade away

What it takes to run
The native desktop app is simple, but a full private cross-platform service and automation setup is most reliably deployed with Docker
Where your data lives

For ILovePDF Premium, merge, split, compress, convert, and annotate PDFs without uploading them to a vendor. The hard boundary is simple hosted delivery, mobile apps, desktop tools, ocr, and batch capacity, plus document fidelity, identity, and compliance.
