Is Smallpdf safe to use?
Absolutely. Smallpdf is ISO 27001 certified and GDPR and eIDAS compliant, and comes with advanced TLS encryption for file transfer security. Users with a free or paid account can store their documents online using the file storage service, which can be disabled at any time.
Are digital signatures legal?
Digital sealing comes with an Advanced Electronic Signature that carries an LTV (Long-Term Validation) timestamp for verifying signatures. Digital signatures are legally binding, but we encourage you to check in with your local signing laws or contact a legal professional for more details.
Is it possible to process documents offline?
With Smallpdf, offline document management is a reality. Some documents shouldn’t be processed online or saved to the cloud. For those special cases, or when you have limited or no internet access, we have the Smallpdf Desktop App for Windows for secure offline document processing.
