Local Processing & Complete Privacy

Your files never leave your device. Learn how our client-side processing technology protects your privacy while delivering professional-quality image and video conversion.

How Local Processing Works

1

Files Stay in Your Browser

When you select images, they're loaded directly into your browser's memory. No uploads happen – the files remain completely under your control on your local device.

Technical Implementation

How We Achieve Local Processing

Our privacy-first approach is built on modern web technologies that enable powerful image and video processing directly in your browser, without any server-side dependencies.

Frontend Technologies:

  • WebAssembly (WASM) - Near-native performance for image processing
  • Canvas API - Direct pixel manipulation and rendering
  • File API - Secure local file access without uploads
  • Web Workers - Background processing without UI blocking

Processing Libraries:

  • FFmpeg.wasm - Video encoding and conversion
  • ImageData API - Raw pixel data manipulation
  • WebCodecs API - Hardware-accelerated encoding
  • OffscreenCanvas - High-performance rendering
