Process PDFs privately: no upload, no storage

1 min read·25 July 2026

Many online PDF tools send your files to external servers. PDFrust works differently: all processing happens locally in your browser. Your files never leave your computer.

How PDFrust works

PDFrust uses JavaScript libraries (PDF-lib for editing, PDF.js for display) that run in your browser. When you upload a PDF, the file is not sent to a server — it stays on your device and is processed by the browser code.

Why this matters

Many PDF files contain sensitive information: contracts with financial data, medical reports, legal documents, tax returns. If an online tool uploads your file to a server, you risk third-party data storage, data breaches, and GDPR violations.

Ideal for GDPR compliance

For businesses complying with the General Data Protection Regulation (GDPR), local processing is an important factor when choosing tools for sensitive documents.

Open source libraries

PDFrust is built on open source software: PDF-lib and PDF.js are publicly available and audited. You can verify how your files are processed.
