CoolPDF vs Smallpdf: Free Limits Compared
Smallpdf is a polished, popular PDF tool, but its free plan allows only two tasks per day and requires uploading your documents to its servers; Pro starts at around $12 per month. CoolPDF imposes no daily task limit at all and never asks for an account, because it runs every tool locally in your browser. For high-frequency, everyday PDF work, CoolPDF is the less restricted and more private choice.

Open CoolPDF toolsFrequently asked questions
Is the 2-tasks-per-day limit real?
Yes. Smallpdf’s pricing page lists the free plan as limited to two documents per day; hitting the cap means waiting until the next day or upgrading to Pro. CoolPDF has no equivalent cap — you can run the tools as many times as you like, because the work happens on your device rather than on rented servers.
Which is better for sensitive files?
Smallpdf states that files are transferred over TLS and deleted after a short retention window. That is reasonable for many documents — but if the file is a contract, medical record, or financial statement, the safest option is not sending it anywhere at all, which is exactly how CoolPDF works.
When is Smallpdf worth paying for?
If you regularly need e-signatures, AI summaries, or native apps with offline workflows, Smallpdf Pro is a fair price. If your work is mostly merging, splitting, compressing, converting, and protecting PDFs, CoolPDF covers it free without limits.
