PDF24

When to Choose Each

Choose PDF24 if you want the best free PDF toolkit available, period. PDF24 is 100% free, open-source, and made in Germany. Its 24-tool suite covers everything from merge and split to OCR, watermarking, and protection — more tools than any competitor. user reviews (4.8★/105) are authentic and detailed, community feedback is pure positive (6P/0N), and there are zero risk flags. Best for every user category: students, professionals, privacy-conscious individuals, and anyone who doesn’t want to pay for PDF tools.

Choose Smallpdf if you specifically need a web-only PDF tool with OCR and don’t mind paying $12/month — the most expensive price in the tag. Smallpdf has a clean, modern interface and a solid feature set (compress, convert, merge, split, sign, edit, protect, OCR). However, Community members consistently warn about subscription trap billing: impossible cancellation, unexpected charges, and rude customer service across multiple independent threads. The rating distribution (95% 5-star on 1,763 reviews) is also suspicious. Only pick Smallpdf if you’ve exhausted free alternatives and understand the billing risks.

Key Differences

Verdict

PDF24 dominates at 4.75 vs 3.0 — the largest score gap between any two tools in the compares list. PDF24 is free, has more features (including OCR), better reviews, better community feedback, desktop apps, and zero risk flags. Smallpdf costs $12/month and has serious subscription trap issues. There is almost no scenario where Smallpdf is the better pick. PDF24 even matches Smallpdf on OCR. The only hypothetical reason to choose Smallpdf would be if you preferred its web interface design — but that’s not worth $12/month when PDF24 does everything for free.
