Questions
No. It is converted in this tab with your browser, so the file never leaves your computer.
MP4 is the most widely accepted video format: phones, editors, YouTube and most websites take it.
WAV is uncompressed sound. It keeps every detail, so files are large: about 10 MB a minute for CD-quality stereo. Editors such as GarageBand and Logic work with it.
The sound is saved uncompressed, so nothing more is lost. The file is much larger than the video's own sound track.
The file is handled in your browser's memory, so very large files can fail. Close other tabs and try again.
