Which one should you use?
Smallpdf has a polished UI and strong OCR, but the 2-task-per-day cap quickly becomes frustrating for regular users. Their Pro tier starts at $12/month — not trivial for occasional PDF tasks.
PDFInOne gives you unlimited access to 26 tools forever, at zero cost. No task counting, no upgrade prompts, no watermarks. And because everything runs locally in your browser, there's no privacy concern at all.
If you process more than two PDFs per week, PDFInOne saves you both time and money. For sensitive documents, it's also the clearly safer option.
