What is an AVI to GIF converter?

An AVI to GIF converter turns Audio Video Interleave (.avi) videos into looping animated GIFs you can open almost anywhere. People search for “avi to gif”, “avi gif”, and “avi a gif” when chat apps, email clients, or CMS tools reject AVI attachments. This free online tool decodes your AVI in the browser with FFmpeg, builds a color palette, and lets you download a GIF with width and FPS controls — without uploading your video.

Tips for converting AVI to GIF

Keep GIFs small and smooth.
  • 01

    Trim long videos first

    Short clips convert faster and stay under chat size limits.

  • 02

    Start around 480px and 12 FPS

    A good default for messaging; raise FPS only if motion looks choppy.

  • 03

    Unsupported codec?

    If conversion fails, re-export the AVI as MP4 (H.264) in a desktop tool, then convert that clip — or try a shorter segment.

  • 04

    Compress after export

    If the GIF is still large, run it through /gif-compressor or /gif-resizer.
