How do I convert an AVI file to M4V?

Select your AVI file or drag it onto the converter, choose M4V as the target format, set the video codec to H.264 and audio to AAC if you want maximum compatibility, then start the conversion. Once finished, download the M4V file — no software installation is needed.

Why convert from AVI to M4V?

AVI files often use old codecs like DivX or MJPEG, causing huge file sizes and playback issues on Apple devices, Android, and web players. M4V uses H.264/AAC, which delivers up to 90% smaller files, preserves 1080p/4K quality, and works natively with iTunes, iPhone, Apple TV, and most browsers.

What happens to video resolution, audio bitrate, and subtitles when converting AVI to M4V?

The converter re-encodes video to H.264 and audio to AAC with a configurable bitrate. Resolution, frame rate, and aspect ratio are preserved. Text-based subtitles inside the AVI are kept as separate tracks in the M4V; image-based subtitles will only appear if you enable the burn-in option.

Is AVI-TO-M4V free to use?

Yes, AVI-TO-M4V on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! AVI-TO-M4V works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
