How to convert AVI to MP4
AVI (Audio Video Interleave) is a decades-old container format developed by Microsoft that remains common in older camcorders, screen recording software, and Windows-based video tools. MOV is Apple’s QuickTime container format, widely used in Final Cut Pro, iMovie, and throughout macOS and iOS. Converting AVI to MOV lets you bring legacy footage into Apple editing workflows without compatibility errors.
BoltConverter sends your AVI file to our processing servers, re-wraps the video stream into a MOV container, and makes the download available within seconds. Both the original upload and the converted file are deleted from the server immediately after you download, so your footage does not linger on any third-party system.

Frequently asked questions
Will the video and audio quality change when converting AVI to MOV?
No quality is lost during the conversion. BoltConverter re-wraps the existing video and audio streams into a MOV container without re-encoding them, so the image and sound remain identical to the original AVI.
Why does Final Cut Pro or iMovie reject my AVI file?
Apple editing apps have limited support for the AVI container format and the codecs commonly used inside it, such as DivX or Xvid. Converting to MOV gives you a container those apps are designed to handle.
Is there a file size limit?
BoltConverter supports AVI files up to 500 MB. For larger files, consider splitting the video before converting.
How long does conversion take?
Most conversions finish in under a minute. The actual time depends on file size and current server load.
Are my files stored after conversion?
No. Both the uploaded AVI and the converted MOV are deleted from our servers as soon as you download the result.
Does MOV work on Windows?
Yes. MOV files play in VLC, QuickTime for Windows, and any media player that supports the QuickTime container, which includes most modern players on Windows.
