Questions

About converting AVI to MP4.

Does converting AVI to MP4 reduce the quality?

With the default settings most videos keep their original quality. If you change any video setting or set a start or end time, the video is converted with those settings and the picture can change slightly.

My AVI file has several audio tracks. Which one do I get?

All of them. The MP4 file keeps every audio track with its language, and the track marked as default stays the default. Tracks that contain no sound are left out.

Will the MP4 file have a watermark?

No. Converted files never get a watermark, free conversions included.

What happens to my files after the conversion?

Your files are processed on servers in the EU and deleted automatically after 24 hours.
