AVI files typically carry older codecs such as DivX, Xvid or MJPEG, so this is a genuine re-encode. Modern H.264 usually reaches equal or better quality at a fraction of the size.
Old AVI footage is often low resolution to begin with; converting cannot add detail that was never captured.
Privacy Notice: All AVI to MP4 conversions are performed locally in your web browser using WebAssembly technology. Your files are never uploaded to our servers, ensuring complete privacy and security. This also means faster conversion speeds and no file size limits from server restrictions.
