Smallpdf free limits explained
The short version: Smallpdf's free tier limits how many document tasks you can run in an hour and can watermark the output, and it processes files on its servers. For merging, compressing, splitting and images-to-PDF, Useful Hacks has no task limit and adds no watermark.

- Does Smallpdf watermark files?
- Free-tier output has carried a watermark once you pass the task limit. A paid plan removes it.
