Convert video to AVI online

AVI is a classic container still used by older media players, desktop video-editing workflows and some capture devices. This free tool converts MP4, MOV, MKV, FLV, WMV, 3GP, WEBM and MPG files to AVI directly in your browser, so footage opens in software that expects the AVI format.

Browser-based and private

Conversion runs on your device with WebAssembly (ffmpeg.wasm) — your video is never uploaded to a server. There is no account, no watermark and no limit, so you can convert as many files to AVI as you like.

Adjust quality and size

Before converting you can set the video bitrate, resolution, frame rate and audio options, letting you balance AVI quality against file size for editing, playback or archiving.

Frequently asked questions

How do I convert a video to AVI?

Open the tool, add your MP4, MOV, MKV, FLV, WMV, 3GP, WEBM or MPG file, keep AVI as the output and click convert. The AVI file is generated in your browser and downloads right away.

Is the video to AVI converter free?

Yes. Converting video to AVI is completely free, with no sign-up, no watermark and no limit on file count or size.

Why convert to AVI?

AVI is widely supported by legacy media players and many desktop video editors, so converting to AVI helps when a program or device will not open newer formats like MP4 or MKV.

Are my files uploaded anywhere?

No. Everything is processed locally in your browser through WebAssembly, so your videos stay on your device and are never sent to a server.

Which formats can I convert to AVI?

You can convert MP4, MOV, MKV, FLV, WMV, 3GP, WEBM and MPG to AVI, and adjust the bitrate and resolution to control the output.

Does AVI keep good quality?

Yes — with a high enough bitrate the AVI output stays close to the source. AVI files can be larger than MP4 at the same quality, so adjust the settings to balance quality and size.
