Two differences that matter: limits and uploads
Smallpdf's free tier limits how many tasks you can complete before it asks you to upgrade to Pro, and like most online services it processes your files in the cloud — meaning they're uploaded, worked on, and later deleted. That's fine for many people, but it's two friction points you don't have to accept.
Unfuss runs each tool as JavaScript inside your browser with engines like pdf-lib and pdf.js. There's no task counter, because there's no server doing the work — it's your own device. And nothing is uploaded, so sensitive documents stay private by default.

Where Smallpdf is the better pick
In fairness, Smallpdf has a broad, well-designed suite: OCR, PDF-to-Office conversions, e-signature workflows, and apps for desktop and mobile. Those features are hard to match in a browser, and if your work depends on them, Smallpdf earns its reputation.
Where Unfuss wins
For the everyday jobs — compress, merge, split, rotate, delete pages, extract pages, JPG to PDF, PDF to JPG, sign, and protect — Unfuss has no daily cap and never uploads your file. Do as many as you like, on documents you'd rather keep to yourself.
