Security and Compliance at Smallpdf
We take security seriously, which is why we’ve implemented multiple layers of protection and earned certifications that prove our commitment to keeping your data safe.
ISO 27001 Certification and Security Standards
We comply with the globally accepted ISO/IEC accreditation for applying an information security management system (ISO 27001:2013). ISO is an international organization with the goal to create standards in many areas.
This means we have an excellent security system in place, always keep it operational, and continually take measures to improve it.
These standards ensure that products and services are safe, of high quality, and efficient. ISO operates as an independent, non-governmental agency, ensuring their process is free of bias or political influence.
Privacy Regulations and Data Protection
We comply with major data privacy laws to protect your rights:
- GDPR (General Data Protection Regulation): Gives you control over your personal data in the EU.
- CCPA (California Consumer Privacy Act): Protects California residents’ privacy rights.
- Swiss Federal Data Protection Act: Provides additional privacy protections as a Swiss company.
Who Can See Your Documents
When you upload a document to Smallpdf, only you can see it. Only you can view, edit, or otherwise access your files unless you explicitly give them permission to do so. The above-mentioned state-of-the-art TLS encryption and our secure servers guarantee the safety of your data.
How Smallpdf Stores and Deletes Your Files
Your files are your business, not ours. Our job is to help you get things done—whether that’s making your PDF smaller, combining documents, or converting files hassle-free. Here’s exactly what happens to your files and when they’re deleted.
Temporary Processing and Deletion Timelines
We have automatic processes in place that scan our servers continuously and delete files permanently. Here are the specific timelines:
- Free tool usage: Files deleted after 1 hour
- Account file storage: Files kept as long as you want, deleted within 1 hour of your deletion request
An integral part of our pledge to keep your data safe is the location of our servers where your data is processed. Our servers are located in Ireland, so they fall under the data laws of the European Union, which are much stricter and more user-centric than other jurisdictions.
Account Cloud Storage Controls
If you use our online file storage with a Smallpdf account, these files are kept as long as you want on our servers. Should you delete a file from your online storage, we’ll remove it from our servers within an hour (in case you clicked “delete” on the wrong file). We do not keep any part of your file post-removal.
