Free audio & video converters
Extract the audio from a video, convert iPhone MOV recordings to MP4, change audio between MP3, WAV, M4A, FLAC and OGG, or turn a clip into a GIF.

Questions about audio & video converters
Is there a file size limit for video?
Without an account you can convert one file up to 25 MB a day. Free accounts handle files up to 50 MB; paid plans up to 1 GB. Very large videos also depend on your device’s memory.
Why does the first conversion take longer?
The first audio or video conversion downloads the conversion engine (about 30 MB). It’s cached, so later conversions start immediately.
Will converting MOV to MP4 lose quality?
If the video is already H.264 it is copied without re-encoding, so there is no loss at all.
