When to Convert
Common scenarios where this conversion is useful
Repurposing classic video clips
AVI is a legacy format common in older video libraries. Convert short memorable clips into GIFs to share on modern platforms like Twitter, Discord, or Reddit without compatibility issues.
Animated demonstrations for documentation
Convert AVI screen recordings or tutorials into animated GIFs that can be embedded directly in README files, wikis, or support articles without requiring a video player.
Social media meme creation
Many older meme-worthy clips exist as AVI files. Converting them to GIF makes them instantly shareable on platforms like Giphy, Tenor, or in direct messages.
Email newsletter animations
Email clients widely support animated GIFs but block video embeds. Convert AVI product demos or teaser clips to GIF format for use in email marketing campaigns.
How to Convert AVI to GIF
-
1
Upload your AVI file
Drag and drop your .avi file onto the converter, or click to select it. AVI files with DivX, Xvid, MJPEG, or other common codecs are all supported. Short clips under 20 seconds produce the best GIFs.

FFmpeg converts with palette optimization
Your file uploads securely over HTTPS and FFmpeg processes it in two passes — first analyzing the footage to build an optimal 256-color palette, then rendering each frame with Floyd-Steinberg dithering for maximum quality.

Download and share the GIF
Download your animated .gif file. It loops automatically everywhere — browsers, Discord, Slack, iMessage, and email clients. Both your AVI and resulting GIF are deleted from our servers immediately after download.
Frequently Asked Questions
FFmpeg supports virtually all common AVI codecs including DivX, Xvid, MJPEG, Cinepak, Indeo, and uncompressed AVI. If your AVI file plays in VLC, it will convert correctly.
GIF compression is far less efficient than modern video codecs. Even older AVI codecs like DivX outperform GIF significantly. A 10-second AVI at 1MB may become a 15-40MB GIF. Use clips under 15 seconds.
Approximately, but not exactly. GIF is limited to 256 colors per frame. Our converter builds a custom palette from your footage, but videos with rich gradients will show some color banding.
No. GIF is a purely visual format. The audio track from the AVI is dropped during conversion.
The GIF is rendered at around 10-15 fps to keep file sizes manageable. The original AVI frame rate is downsampled if it exceeds this range.
Yes. The output GIF is set to loop infinitely, which is the standard expectation for animated GIFs on the web and in messaging apps.
The upload limit is 500MB. AVI files can be quite large due to older compression standards, so trimming to just the clip you need before uploading is recommended.
Yes. Files are uploaded over HTTPS and deleted from our servers immediately after conversion completes. We do not retain or share your content.
In addition to the 256-color limit, GIF files may be scaled down to reduce file size. The AVI source resolution is maintained where possible, but very high-resolution source videos may be downscaled.
Yes. If you need a compact video rather than an animated GIF, you can use the AVI to MP4 converter on ChangeThisFile for much better compression.
