Security Architecture

In an age of data breaches, we take a radical approach: We don't collect your data.Traditional online tools upload your files to a cloud server to process them. This creates a risk that your sensitive PDF contracts or private photos could be intercepted or stored.

For heavy lifting like video processing, we use FFmpeg compiled to WebAssembly (Wasm) — running entirely inside your browser tab. For other tasks like image editing and PDF manipulation, we use modern JavaScript libraries that operate directly on your device's memory. Either way, your file never leaves your device.

Who is this for?
