How to Convert MOV to MP4 on Linux — 4 Free Methods

1. Open convertlo.pro/mov-to-mp4.html in Firefox, Chrome, or Chromium on your Linux machine.
2. Drag and drop one or more MOV files onto the converter, or click Browse to select them.
3. Conversion runs entirely in your browser using FFmpeg.wasm — the video never leaves your machine. No server upload.
4. Click Download to save each MP4 to your Downloads folder.

Works on Ubuntu, Fedora, Arch, Debian, Mint, Pop!_OS, and any other distro with a modern browser. No codec installation required, no flatpak, no snap. Good for large files and batch conversion.

ffmpeg is the gold standard for video conversion on Linux. The -c copy flag skips re-encoding entirely — it just repackages the existing video and audio streams into an MP4 container. The output is bit-for-bit identical to the input. Conversion is nearly instantaneous even for large files.

sudo apt update
sudo apt install ffmpeg

sudo dnf install ffmpeg

sudo pacman -S ffmpeg

sudo zypper install ffmpeg

Step 2: Convert a single file (zero quality loss)

ffmpeg -i input.mov -c copy output.mp4

Replace input.mov with your actual filename. The output MP4 is created in the same directory.

Step 3: Batch convert an entire folder

for f in *.mov; do ffmpeg -i "$f" -c copy "${f%.mov}.mp4"; done

Run this from the directory containing your MOV files. Each file is remuxed to MP4 in sequence. Add -loglevel quiet to suppress verbose output.

Recursive batch convert (subdirectories too)

find . -name "*.mov" -exec sh -c \
  'ffmpeg -i "$1" -c copy "${1%.mov}.mp4"' _ {} \;

When to re-encode instead of remux: If the MOV uses a codec that isn't MP4-compatible (rare, but ProRes or older DV streams can cause issues), replace -c copy with -c:v libx264 -crf 18 -preset slow -c:a aac -b:a 192k. This re-encodes to H.264, which is universally compatible.

1. Install VLC if not already present: sudo apt install vlc (Ubuntu) or your distro's equivalent.
2. Open VLC and go to Media → Convert / Save… (keyboard shortcut: Ctrl + R).
3. Click Add… and select your MOV file. Then click Convert / Save.
4. In the Convert dialog, click the Profile dropdown and choose Video — H.264 + MP3 (MP4).
5. Click the wrench icon next to the profile to review settings. The defaults are good for most files.
6. Under Destination, click Browse and set the output filename with a .mp4 extension.
7. Click Start. VLC's status bar shows conversion progress.

VLC re-encodes the video (unlike ffmpeg's -c copy), so conversion takes longer. Quality at default settings is excellent for most uses. VLC bundles its own codecs so it works even if your system is missing H.264 libraries.

1. Install HandBrake:

   # Ubuntu / Debian (Flatpak)
   flatpak install flathub fr.handbrake.ghb
   
   # Fedora
   sudo dnf install handbrake-gui
   
   # Arch
   sudo pacman -S handbrake

2. Open HandBrake and click Open Source. Select your MOV file.
3. Under the Presets panel on the right, choose Fast 1080p30 (or match your source resolution).
4. Ensure the Format (Summary tab) is set to MP4.
5. Under the Video tab, set Quality (RF) to 18–22. Lower values = better quality, larger file. 20 is a reliable default.
6. Click Start Encode. HandBrake shows a live encoding progress bar.

HandBrake is the right choice when you want to compress a large MOV significantly, target a specific file size, or trim/crop the video before converting. For simple format conversion without size reduction, ffmpeg's -c copy is faster and preserves more quality.
