MP4 to AVI Converter

Convert MP4 to AVI for older software and devices that still require the legacy format - privately in your browser.

About this converter

AVI is a legacy Microsoft container from the 1990s. Most people should stay on MP4, but some older programs, hardware players, and editing tools still expect AVI - and that is what this converter is for.

Converting MP4 to AVI re-encodes the video into an AVI-compatible codec. Because AVI is an older, less efficient format, the resulting file is usually larger than the MP4 you started with.

MP4 to AVI: good to know

Mainly for legacy software or devices that only accept AVI - otherwise stick with MP4.
Expect a larger file, since AVI's codecs are less efficient than H.264.
This is a re-encode, so choose High quality if you want to stay close to the source.

How it works

Drop your file(s) in the box above (or click to browse).
Make sure AVI is selected as the output.
Click Convert, then Download your file.

Frequently asked questions

How do I convert MP4 to AVI?

Drop your MP4 above, choose AVI as the output, optionally set quality under Options, then click Convert and Download.

Why would I convert MP4 to AVI?

Only if an older program, device, or workflow specifically needs AVI. For modern use, MP4 is smaller and far more compatible.

Will the AVI be bigger than the MP4?

Usually yes. AVI uses older, less efficient codecs, so the file tends to be larger at the same quality.

Does converting to AVI lose quality?

It is a re-encode, so there is some loss. Use the High setting to keep it minimal.

Are my files uploaded?

No. The conversion runs in your browser - nothing leaves your device.
