FAQ
Is the MPG to MP4 conversion lossless?
The converter re-encodes with quality-preserving settings (CRF ~18–23), so visual quality stays practically identical while the file becomes fully MP4-compatible.
Do I need to install anything?
No. The converter runs on WebAssembly inside your browser. Nothing to install, no account required.
Are my files uploaded anywhere?
Never. Files are read with the browser File API and processed on your own device. The page even works offline once loaded.
