100% Transparent & Client-Side Safe

Frequently Asked Questions (FAQ)

Comprehensive insights into our zero-upload architecture, file privacy standards, WebAssembly execution, and copyright policies.

Absolutely NOT (Zero-Upload Guarantee). Every file you select (PDFs, images, videos, text, or tokens) is processed 100% locally inside your device's browser memory.

Zero bytes of your files are ever transmitted across the internet to our servers or any third-party infrastructure. You can independently verify this at any time by pressing F12 → Network tab: no upload requests (POST/PUT) are made during file manipulation.

SafeWebUtil leverages cutting-edge browser standards to achieve desktop-class performance:

WebAssembly (Wasm)

High-performance C/C++/Rust engines running compiled bytecode directly on client hardware at near-native execution speed.

Web Workers

Intense computations (OCR recognition, heavy PDF parsing) run in isolated background threads, keeping the browser UI 60fps responsive.

Web Crypto API

Hardware-accelerated cryptography standards for AES-GCM encryption, SHA hashing, and cryptographically secure random generation.

HTML5 Canvas & Stream APIs

In-memory pixel manipulation, EXIF stripping, high-fidelity image compression, and dynamic format conversion.

100% belongs to YOU. SafeWebUtil functions strictly as an in-browser utility engine, similar to software running on your desktop. We never claim, store, retain, or demand any intellectual property rights, licenses, or royalties over your original documents or exported deliverables.
