How do I convert an AVS file to MP4?

Click 'Choose File' to upload your AVS video, select MP4 as the output format, then press 'Convert'. The re-encoding process may take a few minutes depending on file size. After conversion, download your MP4 directly to your device.

Why should I convert AVS to MP4?

AVS is a high-efficiency video codec widely used in Chinese broadcasting but barely supported by consumer hardware and editing software. MP4 with H.264 is universally compatible with browsers, smartphones, media players, and NLEs, and usually offers better compression, reducing file size while maintaining visual quality.

What happens to data like resolution and audio when converting AVS to MP4?

Our converter preserves the original resolution, frame rate, and aspect ratio. The audio track is re-encoded to AAC with a bitrate matched to the source to avoid quality loss. Color profile metadata (like Rec.709) is retained. Since AVS does not support transparent layers or embedded subtitles, those elements are not carried over; any subtitles would need to be added separately.

Is AVS-TO-MP4 free to use?

Yes, AVS-TO-MP4 on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?
