Security and Document Privacy Standards
WeLovePDF is engineered with a strict Zero-Knowledge Architecture. Your documents, sensitive financial records, and personal IDs never leave your device for standard document operations.
Client-Side WebAssembly
Operations like Merging, Splitting, Rotating, and Compressing run directly on your device CPU using high-performance WebAssembly. Zero file bytes are transmitted across the public internet.
Zero-Server Retention
We operate without persistent document storage databases. Your files are never cached, archived, or used for AI training models. When your session ends, all temporary artifacts vanish.
End-to-End Encryption
For advanced server utilities (such as high-speed OCR or AI summarization), communication is secured with TLS 1.3 256-bit encryption. Files are processed in ephemeral RAM and purged in < 60 seconds.
How We Protect Your Confidential Documents
Unlike traditional cloud PDF converters that upload entire sensitive files to third-party data centers, WeLovePDF shifts processing workloads directly to your client browser environment. Whether you are resizing a confidential legal contract, merging medical transcripts, or compressing an exam application form, your data stays under your physical control.
Frequently Asked Privacy & Security Questions
Do you store or view my uploaded PDF files?
No. For over 90% of our operations (merging, splitting, compressing, rotating, watermarking), files are parsed directly inside your device's browser memory using WebAssembly. No bytes are sent to any remote server or stored in any database.
How does client-side WebAssembly sandboxing work?
When you select a document on WeLovePDF, your web browser downloads compiled WebAssembly libraries (e.g., pdf-lib, pdfjs). Processing runs locally on your computer's CPU. When you close the browser tab, the memory is instantly freed.
What happens during server-assisted tasks like OCR or AI Summarization?
For advanced features requiring high-compute machine learning models, files are transmitted via 256-bit TLS/SSL encrypted streams to ephemeral compute workers. Files are processed entirely in volatile RAM and automatically deleted immediately upon task completion (TTL < 60 seconds).
Is WeLovePDF compliant with GDPR and international data regulations?
Yes. Under GDPR Article 25 (Data Protection by Design) and Article 32 (Security of Processing), WeLovePDF ensures zero persistent data retention, zero file indexing, and zero third-party data broker sharing.
Can governmental, corporate, or financial documents be processed securely?
Yes. Because core manipulation occurs locally on your machine without cloud uploads, sensitive government IDs, tax filings, legal contracts, and financial statements remain strictly within your local machine boundary.
