Convert your AVI to MP4 Online

Video plays a huge role in how we watch, share, and save content. From personal recordings to professional media, video is everywhere. But one issue many people face is file compatibility. Not all devices or platforms can play every type of video file. One of the most common challenges is dealing with AVI files and needing them in a more widely accepted format like MP4.
 

If you have an AVI video that won’t play properly or takes up too much space, converting it to MP4 is the perfect solution. And the good news is that with Convertio, you can do this online for free. No complex software, no technical steps, just a few clicks.
 

This guide will explain everything you need to know about AVI and MP4 formats, why you should convert AVI to MP4, and how to use Convertio for easy, fast, and secure conversions.
 

What is an AVI File?

AVI stands for Audio Video Interleave. It’s a multimedia container format developed by Microsoft in 1992. It can hold both video and audio data in a single file, which makes it popular for storing movies, TV shows, and other video content.
 

Key features of AVI files:

  • High quality: AVI files often store video in a less compressed form, which means the quality is very good.

  • Large file size: Because AVI files are less compressed, they take up more storage space.

  • Compatibility: AVI files work well on Windows but can be harder to play on other systems, like Mac or mobile devices.
     

While AVI is still used, it has become less popular because of its large file size and limited compatibility with modern devices.
 

What is an MP4 File?

MP4, short for MPEG-4 Part 14, is one of the most common video formats today. Almost all devices, apps, and online platforms support MP4.
 

Key features of MP4 files:

  • Smaller size: MP4 uses advanced compression, so it reduces file size without losing much quality.

  • Compatibility: MP4 files work on smartphones, tablets, laptops, smart TVs, and almost every video player.

  • Streaming friendly: MP4 is the standard for online platforms like YouTube, Facebook, and Instagram.

  • Versatile: MP4 can store video, audio, images, and even subtitles.
     

This makes MP4 the preferred format for sharing, streaming, and storing videos.
 

Why Convert AVI to MP4?

There are several reasons why converting AVI to MP4 is a smart move. Here are the main benefits:
 

1. Smaller File Size

AVI files can be very large because they use less compression. This makes them harder to store and share. MP4 files are much smaller but still keep good quality.
 

2. Better Compatibility

MP4 files play smoothly on almost all devices and platforms. Whether you use Windows, Mac, Android, or iOS, MP4 is supported everywhere.
 

3. Easy Sharing

If you want to upload a video to YouTube, send it through email, or share it on social media, MP4 is the right choice. Most platforms don’t accept AVI.
 

4. Streaming Support

AVI files are not designed for online streaming, while MP4 is the standard format for video streaming.
 

5. Storage Efficiency

Converting AVI to MP4 saves storage space on your computer, phone, or cloud.
