AVI to MP4 format notes
Before converting, check whether your goal is smaller file size, stronger compatibility, editable output, or better visual quality. Lossy formats usually reduce file size, while lossless or document formats may preserve more detail but create larger files. When quality matters, keep a backup of the original source file and compare the result before deleting anything.
