Convert AVI files to GIF in seconds. Everything runs on your device — nothing is uploaded.
AVI is an older Windows container still used by some legacy software. GIF is a silent, looping animation perfect for memes, previews and chat. This tool converts AVI to GIF locally using ffmpeg.wasm, so the file never touches a server — useful for private videos, client work, or just avoiding slow uploads. Drop an AVI file above, the output format is already set to GIF, and your download is ready in seconds.
Drop or select video/audio from your computer. The drop zone is replaced by a preview of your files. Nothing is uploaded.
Wait until the green “Engine ready” banner appears. Convert stays disabled until then. Pick MP4, MOV, MP3 or WAV and click Convert.
When conversion finishes, the green Download button appears. Save the file instantly to your device.
