Three things most PDF tools won't tell you

01

They store your data

Most online tools upload your sensitive documents to their servers. We process everything locally in your browser.

03

Hidden subscriptions

We believe essential tools should be accessible. No credit card required for our core set of 28 powerful utilities.

How it works

Privacy is not a feature. It's our foundation.

When you drop a file into PDFCub, it's read by your browser's local engine. We don't have a database of your files because we don't have a server that reads files. This is the future of document security.

  • No data retention policy needed.
  • GDPR & HIPAA compliant by design.
