Free AVI to MP4 converter
AnyConv365 helps you convert AVI files to MP4 without installing software. Open this page, choose your file, and download the result.
MP4 is the most common shareable video container. Convert into it from MOV/MKV/AVI for uploads, extract MP3 for audio-only, or convert to M3U8 when you need an HLS streaming package.
How it works
Is AVI to MP4 conversion free?
Yes. AnyConv365 lets you convert AVI to MP4 online for free with no account required.
Will my file quality be preserved?
We aim for the best practical fidelity for each pair. Preview the download before sharing when quality is critical.
Do you store my files?
Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.
Does converting to MP4 always re-encode?
Often yes for maximum compatibility. Expect encoding time to follow clip length and device speed.
Are old AVI codecs always supported?
Most common AVI files convert fine. Rare legacy codecs may fail — try re-exporting from the original editor if needed.
Where can I learn more about this conversion?
