How to Convert AVI to MOV Online

AVI to MOV: what changes in the file

This tool takes a AVI file, processes it with FFmpeg on DownloadVideo.vn servers and returns a MOV file.

Both AVI and MOV are lossy, so converting adds another generation of compression: a small further loss that is usually hard to notice after one conversion.

How AVI and MOV differ

Property	AVI	MOV
Full name	Audio Video Interleave	QuickTime File Format
Introduced	Microsoft, 1992	Apple, 1991
Compression	lossy	lossy
Common codecs	MPEG-4 Part 2 (DivX/Xvid), MJPEG, MP3	H.264, HEVC, ProRes, AAC
Strengths	opens in almost every desktop player and older editing software	default recording format of iPhone and Mac; can hold editing codecs such as ProRes
Limitations	old design: large files for the same quality; no native playback in web browsers or most phones	some Windows/Android players and web uploaders reject it; files from iPhone are often HEVC, which older devices cannot decode

Measured with a sample file

On September 25, 2026 we ran the tool on our production server with a sample file: a 10-second 1280×720 video (MPEG-4 Part 2 + MP3), 9.2 MB.

Result: 9.2 MB → 3.5 MB, processed in 6.5 s. Output: H.264 video at 1280×720, AAC audio at 44.1 kHz stereo, 128 kbps.

Real sizes depend on your content (how complex the picture and sound are, and the length); the figures only show the order of change.

Before you convert

The tool always re-encodes the picture and sound, even when the source codec would already fit the target format.
Up to 500 MB per file; a conversion that runs longer than 10 minutes is cancelled.
The file is sent to our server for conversion and deleted as soon as processing ends, including when it fails.

Frequently asked questions

Does converting AVI to MOV reduce quality?

Slightly: it is a second round of lossy compression. One conversion is usually hard to notice, but repeated conversions add up.

How does the file size change from AVI to MOV?

With our sample file: 9.2 MB → 3.5 MB. Your file may differ depending on its content.
