Privacy-First Architecture
Unlike 99% of online online image converter — png, jpg, webp tools, Mr. Robot Help operates entirely on your device. When you upload a file, it never travels to a remote server. Instead, we utilize modern browser technologies like WebAssembly (Wasm) and FFmpeg.wasm to process your data locally.
This approach offers three major benefits:
Your sensitive files stay in your browser's memory. No leaks, no hacks, no logs.
Processing speed is limited only by your CPU, not your internet upload speed.
Since we don't pay for cloud bandwidth, we don't impose artificial file size restrictions.
