What is the difference between AVI and MOV?

AVI (Audio Video Interleave) is Microsoft's container format from 1992. It has broad Windows compatibility but lacks modern features like streaming support and efficient metadata storage. MOV is Apple's QuickTime container, natively supported on macOS and iOS. MOV supports modern codecs (H.264, H.265, ProRes, AAC) and is the preferred format for Apple software such as Final Cut Pro and iMovie.

Will converting AVI to MOV reduce quality?

It depends on the codec. If your AVI already uses H.264 video, FFmpeg can rewrap it into a MOV container using -c copy (no re-encoding), resulting in zero quality loss. If the AVI uses MPEG-4, Xvid, or DivX video, re-encoding is required and introduces some quality loss. Use a high-quality bitrate or low RF value in HandBrake to minimize the loss.

Why can't this tool convert the file directly in the browser?

True video transcoding requires full codec libraries and hardware acceleration — features unavailable in browser JavaScript without a hundreds-of-megabytes WASM bundle. The metadata reader uses the browser's built-in File API and runs instantly on your device with no uploads. For actual conversion, FFmpeg on your desktop is fast and free.

Is my video file uploaded anywhere?

No. The file inspector uses the browser's File API and URL.createObjectURL(). Your video file never leaves your device — there is no upload, no server processing, and no tracking of any kind.

Can FFmpeg convert AVI to MOV without re-encoding?

Yes, if the video codec is compatible. Run: ffmpeg -i input.avi -c copy output.mov. This works when the AVI contains H.264 video and AAC or MP3 audio. If it contains Xvid or DivX video, you must re-encode: ffmpeg -i input.avi -c:v libx264 -crf 18 -c:a aac output.mov.

Which codec should I target for the MOV output?

For maximum Apple compatibility, use H.264 video (libx264) with AAC audio. H.264 MOV files open in every Apple app and most Windows players. For professional post-production workflows requiring lossless quality, use Apple ProRes (prores_ks) — note this produces much larger files and requires FFmpeg compiled with ProRes support.

AVI vs. MOV — Format Comparison

Know what you are converting and why

Feature	AVI	MOV
Developer	Microsoft (1992)	Apple (QuickTime)
Common codecs	MPEG-4, Xvid, DivX, H.264	H.264, H.265, ProRes, AAC
Platform	Windows legacy software	macOS, iOS native
Container age	Legacy (1992, limited updates)	Modern (1991–present)
Streaming	Not supported	Supported
Apple editing	Poor (needs conversion)	Native (Final Cut, iMovie)
File size	Larger (older codecs)	Smaller (H.264/H.265)

FFmpeg (Recommended — full codec control)

Free, cross-platform, most flexible

FFmpeg can rewrap AVI to MOV with no quality loss when the source codec is H.264, or re-encode to H.264/AAC for maximum Apple compatibility. Click Copy on any command to paste it into your terminal.

Stream copy (zero re-encoding — H.264 AVI only)

ffmpeg -i input.avi -c copy output.mov

Re-encode to H.264 + AAC (universal compatibility)

ffmpeg -i input.avi -c:v libx264 -crf 18 -preset slow -c:a aac -b:a 192k output.mov

Apple ProRes (lossless quality, large file)

ffmpeg -i input.avi -c:v prores_ks -profile:v 3 -c:a pcm_s16le output.mov

Install FFmpeg

# macOS (Homebrew)
brew install ffmpeg

# Windows (winget)
winget install ffmpeg

# Ubuntu / Debian
sudo apt install ffmpeg

Use -crf 18 for near-lossless quality (larger file) or -crf 28 for smaller file with more compression. Lower CRF = higher quality.

HandBrake (GUI — quality-focused encoding)

Free, Windows / Mac / Linux

Note: HandBrake outputs MP4 and MKV natively. For MOV output, use HandBrake to produce an MP4, then use FFmpeg to rewrap it: ffmpeg -i output.mp4 -c copy final.mov

Download and open HandBrake from handbrake.fr.
Drag your AVI file onto the HandBrake window to load it as the source.
In the Summary tab, set Format to MP4.
Choose a preset such as Fast 1080p30 and adjust quality with the RF slider (RF 18–22 for good quality).
Set a destination file path with an .mp4 extension and click Start Encode.
Run ffmpeg -i output.mp4 -c copy final.mov to rewrap to MOV with no quality loss.

VLC Media Player (GUI — no command line)

Free, Windows / Mac / Linux

Open VLC and go to Media → Convert / Save.
Click Add, select your AVI file, then click Convert / Save.
Click the Edit selected profile wrench icon next to the Profile drop-down.
In the Encapsulation tab, select QuickTime / MOV.
In the Video codec tab, choose H.264 for best Apple compatibility.
Set the destination file with a .mov extension and click Start.

VLC re-encodes the video and writes the output MOV file to your chosen destination.
