What is AVI?

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of Windows 3.1. It was the standard video format for Windows for over a decade and remains widely recognized today.

AVI files can contain both audio and video data, supporting various codecs like DivX, XviD, and uncompressed video. The format's flexibility made it popular for video editing and distribution during the DVD era.

While AVI is still functional, modern formats like MP4 offer better compression and wider device support. Converting AVI files ensures compatibility with current devices and platforms.

Why Convert AVI Files?

AVI remains usable but has limitations that modern formats address:

  • Large file sizes - AVI files are often much larger than equivalent MP4 files
  • Mobile incompatibility - iPhones and many Android devices don't play AVI natively
  • No streaming - AVI can't be streamed efficiently; the full file must download first
  • Platform rejection - Social media and video platforms prefer MP4 over AVI
  • Codec issues - Old AVI files may use codecs that modern players don't support
  • No chapter support - AVI lacks modern features like chapters and multiple audio tracks

Convert AVI to Other Formats

Transform your AVI videos to modern, compatible formats:

AVI to MP4

The most common conversion. MP4 offers universal compatibility, smaller file sizes, and streaming support. Essential for sharing videos or playing on mobile devices.

AVI to MOV

Convert for Apple ecosystem compatibility. Required for editing in Final Cut Pro and optimal playback on Mac/iOS devices.

AVI to MKV

Transform to MKV for high-quality archival with support for multiple audio tracks, subtitles, and chapters.

AVI to WebM

Create web-optimized video for HTML5 browsers. WebM offers excellent compression for online video.

AVI to WMV

Convert to Windows Media Video for Windows-specific applications and older Windows devices.

AVI to MP3

Extract the audio track from AVI videos as MP3 files for music players and podcasts.

Convert Other Formats to AVI

Create AVI files for legacy software and editing compatibility:

MP4 to AVI

Convert for compatibility with older video editing software that doesn't support MP4, or for legacy Windows media players.

MOV to AVI

Transform Apple videos for Windows-based editing workflows.

MKV to AVI

Convert MKV for playback on devices and software that only support AVI format.

WebM to AVI

Transform web video to AVI for editing or legacy player compatibility.

How to Convert AVI Files

  1. Upload your AVI file - Drag and drop your video or click to browse. We handle large AVI files.
  2. Choose your output format - Select MP4 for universal compatibility, or other formats for specific needs.
  3. Download converted file - Get your optimized video ready to play or share anywhere.

Pro Tip

AVI files with DivX or XviD codecs from the early 2000s often have excellent quality. When converting these to MP4, use high bitrate settings to preserve the original quality.

Common Mistake

Keeping large AVI files when storage is limited. Convert to MP4 to reduce file size by 50-80% without visible quality loss. A 4GB AVI might become a 1GB MP4.

Best For

AVI is useful for video editing workflows, legacy Windows software, and archiving uncompressed or losslessly compressed video.

Not Recommended

Avoid AVI for mobile playback, web sharing, or streaming. Use MP4 instead. Also avoid creating new AVI files unless specific legacy software requires it.

Frequently Asked Questions

AVI (Audio Video Interleave) is a video container format created by Microsoft in 1992. It stores video and audio data together and was the standard Windows video format for many years. AVI supports various codecs but has been largely replaced by MP4.

iPhones don't natively support AVI format. Convert your AVI files to MP4 or MOV format, which iOS fully supports, or use a third-party app like VLC for iOS.

MP4 is the best choice for most users. It offers universal compatibility, excellent compression (smaller files), and works on all devices, browsers, and platforms.

With proper settings, quality loss is minimal and often imperceptible. The conversion uses modern compression that's more efficient than older AVI codecs, so you get smaller files with similar visual quality.

AVI files are often large because they use older, less efficient compression or no compression at all. Converting to MP4 with H.264 compression can reduce file size by 50-80% while maintaining quality.

Yes, ChangeMyFile converts AVI to MP4 directly in your browser. Upload your AVI file, select MP4 as output, and download the converted file. No software installation needed.

No, MP4 is superior for most uses. MP4 offers better compression, wider device compatibility, streaming support, and smaller file sizes. AVI is mainly useful for legacy software compatibility.

YouTube accepts AVI uploads, but recommends MP4 for best results. Converting to MP4 before uploading ensures faster upload times and better processing on YouTube's servers.

Your player may lack the codec used in the AVI file. AVI is just a container-the actual video uses various codecs. Convert to MP4 with H.264, which is universally supported.
