PDF Smart Kit gives you 28 PDF tools — merge, split, compress, convert, edit, and protect — that all run inside your browser. Unlike Smallpdf or iLovePDF, your files are never uploaded to a server. Everything is processed on your own device, so contracts, IDs, and tax forms stay private by design. ✓ No sign-up, no watermarks, no daily limits ✓ Works offline once loaded ✓ Free for personal and commercial use
