How can I convert DIVX videos to MP4 with no loss in quality?

I want to play DIVS videos on my Walkman, which supports only .mp4 format. It’s really irritating to convert the videos and have them lose their quality.

    Mike is right. Re-encoding a video file will guarantee at least some quality loss. It's like using a copier and making a copy of a copy. Each time, it will lose quality.

    However, you can get pretty close with the quality with some encoders. Freemake Video Converter does a fairly good job and is pretty quick at it. http://www.freemake.com/free_video_converter/

    I'm not sure what methods it uses, but if you use "Same as source" when converting, it's usually pretty close in quality and size.

    If your Walkman has a smaller screen / resolution, it may not make much visual difference if the video is resized to a smaller resolution and bitrate to make the file size smaller. You should check the compatible video formats to make sure it can handle the resolution and bitrate you're wanting to use.

    Like most video containers and codecs Divx is a compressed video format which means any further encoding will effect the quality of the content.

    The second issue you fill face is that if you manage to encode it with little to no noticeable quality loss you will most likely see a huge increase in file size [since video compression is always based on quality reduction ~ with no reduction there is no room for compression].
