MOV to MP4 Converter
Choose a MOV file and convert it to an MP4 with AVC video and AAC audio. The file stays in your browser and no account is required.
More private browser video tools
Edit or convert one video without sending it to an Instasize processing server. Codec support and processing speed depend on the browser and device.
Edit video
Convert a QuickTime MOV file to MP4
MOV input
This route accepts a .mov file or a video identified as QuickTime. MOV is a container, so successful conversion still depends on the codecs inside it.
Compatible MP4 output
The converter creates an MP4 with AVC video and AAC audio when the browser can decode and encode the source tracks.
Conversion is not restoration
Re-encoding can change quality and file size, and it cannot recover detail already missing from the source.
Output, privacy, and compatibility
Private processing
The selected video is read and processed in this browser with MediaBunny. This workflow does not upload the video to an Instasize processing server.
MP4 output
Completed edits download as MP4 files with AVC video and AAC audio when audio is retained. Re-encoding can change file size and visual quality.
Browser limits
Codec support, speed, and memory limits vary by browser and device. Keep the original file and review the complete result before deleting or publishing anything.

Resizing photos for social media should be a cinch, but most editing programs are a pain to use. Of the dozen I’ve used, Instasize is the fastest, easiest and most consistent...
