About AVI Files

.avi Icon

An .avi file is a multimedia file saved in the Audio Video Interleave (AVI) format, a container format developed by Microsoft in 1992 for storing both video and audio data in a single file. AVI files can contain various video and audio codecs, allowing them to combine high-quality video with synchronized audio for playback on PCs and media players. The format was widely used in the 1990s and 2000s for movies, TV shows, and personal recordings due to its broad compatibility with Windows-based systems.

AVI files are commonly found as downloaded videos, video exports from editing software, or digital archives. Users can open and play .avi files on FileHelper.com by dragging them to this page.

Converting AVI Files

You can convert .avi files into other formats to make them easier to play, edit, or share across different devices and platforms:

  • Converting to MP4: Offers broad support across most devices and streaming sites, producing smaller files with good video quality.
  • Converting to MOV: Works best for Apple devices and professional editing tools such as Final Cut Pro and Adobe Premiere Pro.
  • Converting to WMV: Optimized for Windows environments, making it useful for playback and editing on PCs.
  • Converting to M4V: Designed for smooth playback in iTunes and easy transfer to iPhones, iPads, and other Apple products.
  • Converting to MKV: Keeps high-definition video and allows multiple audio, subtitle, or metadata tracks in one file.
  • Converting to WEBM: Produces lightweight, open-format videos that run directly in most modern web browsers.
  • Converting to GIF: Turns short video segments into looping animations that are easy to share on social media or websites.
