About Rubtin

Rubtin was founded to solve a fundamental security flaw of the modern web: the practice of uploading private documents to remote cloud servers for simple conversions and edits.

We believe that your files are your business. Whether you are combining sensitive legal drafts, extracting personal invoices, or compressing corporate presentations, the process should be safe, simple, and fast.

Files Stay on Your Device

We run all tools locally inside your web browser. No document files are uploaded to remote servers, no cloud storage logs are kept, and no third-party APIs process your information.

Our Vision

We are starting with high-performance PDF tools, but we are actively developing lightweight client-side modules for image editing, developer utilities (JSON formatters, parser units), and financial calculations.
