How to convert ASF to MOV
To convert ASF to MOV, upload your ASF file, choose MOV as the output format and press Convert. The finished MOV file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns ASF videos into MOV files in your browser, with no software to install and no watermark. When the video and audio inside your ASF file can be placed in MOV as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as H.264 video with AAC audio (QuickTime container).
