Smallpdf is the polished incumbent in online PDF tools. It's also the one that walks you fastest into a signup wall: free users see a daily processing cap, and many features push you to a paid plan.
PDFToolBench is a no-signup, no-upload alternative. The trade-off is fewer features overall — we don't do eSign, OCR-to-Word, or document tracking — in exchange for not having to send your file anywhere.
