Will converting AVI to MOV reduce video or audio quality?

No. The conversion is a container remux — FFmpeg copies the existing compressed video and audio streams directly into the MOV structure without decoding or re-encoding them, so quality, resolution, and bitrate stay exactly as they were in the source AVI.

Why won't my AVI file open in QuickTime Player at all?

QuickTime relies on installed codec components, and many AVI files use codecs — Indeo, certain Xvid or DivX builds, older MJPEG variants from webcams — that Apple never shipped decoders for. Converting the container to MOV does not change the codec, but if the codec is one FFmpeg can decode and QuickTime supports (like H.264), the resulting MOV will play without the missing-codec error.

Can I import the converted MOV directly into Final Cut Pro?

Yes, as long as the underlying video codec is one Final Cut Pro accepts, such as H.264 or ProRes. If your original AVI used a more obscure codec, Final Cut may ask you to transcode further inside its own media import pipeline, since MOV compatibility depends on the codec, not just the container.

Is MOV the same thing as MP4?

They are closely related — both use the same underlying ISO base media file format concept, and MOV was in fact the ancestor of MP4. In practice MOV is treated as Apple's native flavor and is what QuickTime-based tools default to, while MP4 is the more universally standardized sibling used across non-Apple platforms.

Will old camcorder or webcam AVI footage convert cleanly?

In most cases, yes, if the footage uses a common codec like MJPEG, DV, or H.264. Very old or proprietary hardware-specific codecs occasionally cannot be decoded even by FFmpeg, in which case the conversion will fail with a codec error rather than producing corrupted output.

Does the converted MOV file work on iPhone and iPad?

Yes, provided the video stream is H.264 or HEVC and the audio is AAC, which is what most consumer AVI files use. The MOV container itself is fully supported by iOS Photos and the Files app.

Why does my MOV file play video but have no sound?

This usually means the original AVI's audio codec (commonly an older ADPCM or a legacy Windows-only codec) is not one QuickTime can decode. The audio stream is still present in the MOV file, but the player lacks a decoder for it — re-encoding the audio to AAC would resolve this, though that is a separate, lossy step from this remux tool.

How large a file can I convert?

Guest users can convert files up to 40 MB. Creating a free account raises that to 80 MB, and Pro accounts can process files up to 250 MB — all still entirely inside your browser, with no server-side upload.

Is my video uploaded to your servers during conversion?

No. FFmpeg runs as WebAssembly inside your browser tab, so the entire remux happens on your own device. The file never leaves your computer.

Can I batch-convert multiple AVI files to MOV?

This tool processes one file at a time to keep browser memory usage predictable. For several files, repeat the process for each — since it is a fast remux rather than a re-encode, converting a handful of files back to back is still quick.

What is AVI to MOV?

AVI is a Windows-native container from the early 1990s, and its relationship with Apple software has always been rocky. QuickTime Player, iMovie, and Final Cut Pro are built around the QuickTime File Format (.mov), and while some AVI files with common codecs will open on a Mac, plenty of others — anything using VfW-only codecs like Indeo, certain Xvid variants, or older DV-AVI captures — either fail to open, play with no audio, or show a codec error. MOV is the format those Apple tools expect natively, and converting to it up front avoids guessing whether a given AVI file will behave.

This tool converts AVI to MOV using a stream copy rather than a re-encode: FFmpeg reads the video and audio data already compressed inside your AVI file and repackages it inside a QuickTime-compatible MOV wrapper without decoding a single frame. The visual quality, audio quality, bitrate, and resolution are identical to the source — only the container structure changes, from the RIFF-based layout AVI uses to the atom-based structure QuickTime expects. Because there is no re-encoding step, conversion is fast even for long recordings, and the result opens reliably in QuickTime Player, iMovie, and Final Cut Pro without the codec compatibility guesswork that AVI files bring to the Apple ecosystem.

Once you have the MOV, Trim Video and Compress Video both work directly on it, or use AVI to MP4 instead if you need a non-Apple-native format.

How It Works

The tool loads your AVI file locally and inspects its stream headers to identify the video and audio codecs already used. If those codecs are ones QuickTime's MOV format supports natively (which is the case for H.264 and most MPEG-4 video, and AAC or PCM audio), FFmpeg performs a direct stream copy (-c copy), lifting the compressed data out of the AVI RIFF structure and writing it into a proper QuickTime atom-based MOV container. This keeps the operation to a remux rather than a transcode, so it finishes in seconds rather than minutes, and preserves quality exactly.

How to Use

Upload your AVI file

Drag your .avi file onto the upload zone or click to browse. Nothing uploads to a server — the file stays in your browser.

Let FFmpeg load

The first time you use any tool on this site, the ~30 MB FFmpeg WebAssembly engine downloads once and is cached for future conversions.

Click Convert to MOV

FFmpeg identifies the codecs already inside your AVI and repackages them into a QuickTime-compatible MOV container.

Wait for the remux to finish

Since no re-encoding happens, most files finish in a few seconds regardless of length.

Download the MOV file

Save the finished .mov file to your device. The original AVI remains untouched.

Open it in Apple software

Import into QuickTime Player, iMovie, or Final Cut Pro, or share it via AirDrop between Apple devices.

Who Uses This Tool

🍎

Digitized Camcorder Footage

Old MiniDV or hard-drive camcorder exports often land in AVI. Convert to MOV once so every future edit on a Mac starts from a format Final Cut and iMovie trust.

🎬

Family Video Restoration Projects

Home movie transfer services frequently hand back AVI files from VHS-to-digital conversions — convert them to MOV before assembling a family archive in iMovie.

🖥️

Fixing "Unsupported Codec" Errors

When QuickTime Player refuses to open an AVI outright, converting it first resolves the container mismatch, though the underlying codec still needs to be one QuickTime supports.

📱

AirDrop and iCloud Sharing

AVI files sent via AirDrop can behave inconsistently across Apple devices; MOV is the format Apple's sharing pipeline is built around, so playback is more predictable.

🗄️

Staying Inside One Editing Ecosystem

Video projects that will be revisited and re-edited repeatedly are easier to manage in MOV, since every Apple app in the chain reads it without a conversion step.

✂️

Screen Recording Cleanup

Some third-party Windows screen recorders default to AVI output. Converting to MOV before importing into a Mac-based editing workflow avoids intermediate format surprises.

Why Choose This Tool

Stream Copy — No Re-encode

The existing video and audio streams are lifted directly out of your AVI file and repackaged as MOV, so quality is identical to the source and the process is fast.

Built for the Apple Workflow

MOV is the format QuickTime, iMovie, and Final Cut Pro are built around, so the converted file behaves predictably rather than triggering codec warnings.

100% Local Processing

FFmpeg WebAssembly runs the whole conversion in your browser tab — your footage, including personal home videos, never touches a remote server.

No Re-encoding Artifacts

Because this is a remux and not a transcode, there is no risk of the double-compression softness that comes from decoding and re-encoding video.

Handles Long Recordings

Since the operation copies streams rather than decoding every frame, even lengthy camcorder or lecture recordings convert in a fraction of the time a re-encode would take.
