Why Convert Video Formats?
Different devices and platforms support different video formats.

Format Options Explained
MP4 with H.264 encoding offers the best balance of quality and compatibility. WebM with VP9 provides excellent compression for web use. AVI uses MPEG-4 for classic compatibility. MOV is Apple's QuickTime format ideal for Mac and iOS. MKV (Matroska) is an open-source container supporting advanced features like chapters and multiple audio tracks.
Quality Settings
Choose High Quality for best output (takes longer), Medium Quality for balanced conversion (recommended), or Low Quality for faster processing. Higher quality preserves more detail but results in larger file sizes.
