PDFKit vs Smallpdf: Privacy-First Alternative to a Cloud PDF Suite
Smallpdf is one of the best-designed PDF toolsets on the web, with a generous free tier and a clean interface. It processes files in the cloud, which means uploads, size limits, and a paid plan for heavier use. PDFKit delivers the same core toolkit — merge, split, compress, convert, protect — with a hard rule: files never leave your device, there are no limits, and it's free.

The Bottom Line
Smallpdf is a polished cloud suite, and its integrations and desktop apps are genuinely useful. But for core PDF tasks, PDFKit matches the essential functionality for free, without uploads, file caps, or accounts — and with the added guarantee that your sensitive documents never leave your computer.
