When it comes to converting videos, audio, or any other multimedia format, I think FormatFactory is the undisputed and definitive best free option. However, it's always good to highlight the excellent alternatives that are emerging every day, such as Aero Convert ; a free video converter that appears simple but supports many formats.
Aero Convert stands out primarily for its minimalist interface design—small yet practical and intuitive, as seen in the screenshot above. This is reflected in its slogan: " A simple and easy way to convert any video file ." It supports the most popular formats, including AVI, FLV, MOV, MP4, and MPEG, and even audio files such as MP3 and WAV.
Aero Convert is only available in English, but as you'll see, the conversion process is simple. It's compatible with Windows 7/Vista/XP and is lightweight; its installer is distributed as a compressed file of 5.14 MB.
