How 100% In-Browser Image Tools Work
When you select files in our image tools, your browser allocates secure sandbox memory using standard HTML5 APIs. Dedicated WebAssembly routines and background Web Worker threads parse and transform your media entirely on your computer's CPU/GPU.
File streams are read directly from disk into typed array buffers in RAM without dispatching HTTP POST requests.
Algorithms execute in isolated Web Workers to prevent main UI freezing and protect sensitive data.
Processed outputs generate temporary blob URLs for instant saving, automatically reclaimed after download.
