AVI (Audio Visual Interleave) is a widely used file format for playing audio and video in Windows, among others. You may need to convert AVI to MP4 (MPEG-4) in those situations where AVI is less suitable or cannot be played, such as on a smartphone, iPod or PSP. MP4 files are the most popular video file format when it comes to mobile devices. You can convert AVI to MP4 using purchased or free software, or by uploading the file to a dedicated conversion website.

To step

Method 1 of 2: Using conversion software

1. Explore the possibilities of free software. Software for converting AVI to MP4 can be downloaded everywhere. User and editor reviews can help you select the best choice for you to convert AVI to MP4. Some options to consider are:
   • Wondershare
   • Xilisoft
   • WinX
   • Convert AVI to MP4
   • Handbrake
   • AutoGK
2. Buy or download the converter of your choice and install it on your PC. While free software is of course preferred, it is important to realize that in some cases where the target file must meet specific requirements (codec, size, etc.), commercial software is the only option.
3. Open the program and read the instructions or tutorials. If you downloaded free software, search the corresponding forums for directions or post any specific questions you have.
4. Open the AVI file with the converter. With most programs you will find an option to add files somewhere, or you can simply drag and drop files to the program window.
5. Choose MP4 as the file format. Adjust the settings for size, resolution, codec, and other properties in settings, if possible.
6. Choose the target file and location and name them if necessary. Open the folder where the target file is to be saved. Skip this step if you want to use the default location for saving converted files.
   • Choose a logical naming convention and optionally the correct extension for the target file.
7. Start the conversion as instructed in the program.

Method 2 of 2: Use a website for the conversion

1. Find a website for the online conversion of AVI files. Check whether all the options you need are available. Many free services have limited functionality.
2. Choose MP4 as the file format.
3. Adjust the settings for the converted target file as needed, if necessary.
4. Enter your email address to receive and download the converted file.
5. Read the terms of use carefully.
6. Start the AVI to MP4 conversion (it varies by application).
7. Check your email if you have received a message that the MP4 file is ready for you.
8. Download the MP4 file.

Tips

• Converters that allow you to "batch" convert can save you a lot of time, because they can convert multiple files at the same time.
• Many programs have "wizard" functions to help you select the best output settings for the playback device you want to use.
• Save your AVI files if they are larger and less compressed than the MP4s. If you need a different file format in the future, you would like to have the source file of the highest possible quality.

Warnings

• Be careful when choosing a program or website to convert your AVI files. In addition to the common ad junk and pop-ups, many programs are offered for free, while afterwards they turn out to be trial versions where you still have to pay for a full conversion.
• Read the terms of use carefully, especially if you are a business user.
• Be careful downloading additional browser toolbars or other extras.
