WizGo

About WizGo

WizGo is a free, secure and fast online toolbox. We believe user privacy is essential, so every tool runs locally in your browser — files and data never leave your device.

Tech Stack

Image Processing

Rust-built WebAssembly modules with imagequant palette quantization and the jpeg-encoder optimization pipeline. Supports PNG, JPEG, WebP, GIF, BMP.

Crypto & Signing

JWT decoding, signing and verification all run on the browser-native WebCrypto API. Supports HS, RS and ES algorithm families with zero third-party dependencies.

Frontend Framework

Built on Astro static-site generation with Tailwind CSS for a clean Vercel-style UI.

PWA Support

Progressive Web App support — installable on desktop and mobile, works offline.

Privacy Policy

WizGo is a pure-frontend architecture; every file is processed inside your browser:

  • Files are never uploaded to any server
  • No personal data is collected
  • A small amount of preference data is stored locally in LocalStorage

Limitations

Due to browser environment constraints, WizGo has the following usage limits:

  • Image files should stay under 100MB
  • Large files may take longer to process
  • Some advanced compression algorithms (mozjpeg trellis, lossy libwebp) are limited by the pure-Rust WASM toolchain
