Smallpdf is an online PDF service operated by Smallpdf AG, a Swiss company. Its core offering is a set of browser-based tools for converting, compressing, editing and signing PDF documents. The provider also offers a mobile app, a Windows app and a Chrome extension. Files are processed through the web environment, so no software needs to be installed for basic use.
Smallpdf AG is incorporated under Swiss law and therefore sits outside the EU. The company states that it complies with the GDPR and the Swiss Federal Act on Data Protection (nFADP), and it holds ISO/IEC 27001 certification. The website does not say in which data centres uploaded files are processed. Organisations that need a fixed EU or Swiss storage location should have this written into the data processing terms before use.
