Technical FAQ

Deep dive into our architecture and security protocols.

How does NanoZipt achieve "Zero-Upload" security?
Unlike legacy tools that require HTTP data transfer to remote servers, NanoZipt utilizes WebAssembly (WASM) to execute complex rendering and compression algorithms directly within your browser's secure sandbox. Your cryptographic keys and document data never leave your device's volatile memory, ensuring absolute data sovereignty.
Is this architecture compliant with GDPR and HIPAA?
Yes. Because NanoZipt operates as a "stateless" client-side utility, no user data is logged, stored, or transmitted to third-party processors. This architecture naturally aligns with strict compliance frameworks by eliminating the "data processor" risk vector entirely, making it safe for legal, medical, and financial workflows.
Why are there no file size limits?
Cloud-based competitors cap file sizes (typically 50MB) to manage server bandwidth and storage costs. Since NanoZipt leverages your local hardware (CPU and RAM), the only limitation is your own device's capabilities. We routinely process 1GB+ engineering blueprints and legal briefs without latency.
Can I use NanoZipt in an air-gapped (offline) environment?
Absolutely. Once the initial lightweight application assets (HTML/JS/WASM) are cached in your browser, you can disconnect from the internet entirely. This capability is crucial for high-security environments where sensitive documents must not be processed on an active network connection.
How does client-side compression affect quality?
Unlike server-side brute-force compression which often applies a blanket reduction, our local engine analyzes the visual complexity of each page. It selectively downsamples high-DPI raster images while preserving vector text and essential metadata, ensuring maximum file size reduction with minimal perceptible quality loss.
