3. VLC Media Player

VLC Media Player is a popular free tool that many already have installed. Beyond playing videos, it serves as a capable MP4 to AVI converter that can often remux files without losing quality. Its wide format support and no-cost nature make it a go-to choice for everyday users who want a versatile desktop solution they can rely on regularly.

• Open VLC Media Player. Click Media > Convert/Save.

• Add your MP4 file and click Convert/Save.

  

• Browse the destination and rename the .mp4 to .avi.

  

• Then from the profile dropdown, click the Gear icon to open the Profile Edition window.

• In the Profile Edition window, go to Encapsulation, tick the AVI box, and click "Save".

  

• Finally, click "Start" to kick off the conversion.

  

4. HandBrake

HandBrake is a free, open-source video transcoder available for Windows, macOS, and Linux. It excels at high-quality re-encoding with modern codecs like H.264 and H.265 while supporting batch processing and extensive customization. Although newer versions dropped native AVI container support, users can achieve MP4-to-AVI results through specific encoder settings and post-processing or by using legacy versions for direct AVI output. Ideal for users needing precise control over compression and quality.

• Download and install the latest HandBrake from the official site (handbrake.fr). For direct AVI support, consider a legacy version like 0.9.x if needed (not recommended for security reasons).

• Launch HandBrake and click Source > Open File to load your MP4 video.

• In the Output Settings section (bottom left), select MP4 or MKV container initially. For AVI-like results, switch to a compatible video encoder such as MPEG-4 or Xvid (in supported versions) under the Video tab.

• Go to the Video tab: Choose your encoder (e.g., H.264 or MPEG-4), set Constant Quality (RF 18-22 for good balance), and adjust resolution/framerate if needed.

• In the Audio tab, select desired codec (e.g., AAC or MP3) and bitrate.

• Set the destination folder and filename (change extension to .avi manually if container allows, or use external muxer for strict AVI).

• Click Start Encode (or add to queue for multiple files). Monitor progress in the queue window.

Notes

For best compatibility in modern HandBrake, encode to MP4/MKV first then remux to AVI using a tool like FFmpeg or MKVToolNix if strict AVI container is required. Always test output on your target player.

5. Any Video Converter

Any Video Converter delivers an approachable desktop experience with helpful presets that simplify convert MP4 to AVI jobs. It works especially well for Windows users who want batch support and basic editing features in one place. The free version covers most common needs, making it a practical choice when you prefer guided options over complex manual settings.

• Click Add Video(s) or simply drag and drop your MP4 file(s) into the program window.

• At the bottom or right side, find the output format section. Select AVI from the list of video formats.

• Choose a preset (e.g., "HD AVI" or "Standard AVI") and customize settings like resolution or bitrate if desired.

• Click Convert and save the AVI file.

6. FFmpeg

FFmpeg is a lightweight, command-line powerhouse favored by advanced users and developers. It provides unmatched precision for MP4 to AVI conversion, allowing everything from simple remuxing to detailed encoding. Though it lacks a graphical interface, its speed, flexibility, and ability to be scripted make it perfect for automation or when you need the highest possible control over your files.

• Install FFmpeg on your computer.

• Open a terminal or command prompt.

• Run the command and wait for completion.
