// engineering principles
Built from the ground up on the principle that your personal files and creative work should never touch a third-party server.
All processing is executed 100% in your device RAM using modern Canvas and WebAssembly. Zero data leak risks.
No email addresses required, no tracking cookies, and no spam. Open the utility, solve your task, and go.
No unsightly watermarks, no artificial daily export limits, and no trial traps. Supported by lightweight, clean ads.
Without network latency or cloud upload bottlenecks, file conversions and operations happen smoothly at 60fps.
