Is converting MP4 to AVI free?

Yes. LessMB converts MP4 to AVI for free in your browser without an account.

Will the AVI be larger than the MP4?

Often yes. AVI typically uses less efficient codecs, so the output may be larger than the MP4 source.

Are files uploaded?

No. Conversion runs locally in your browser session.
