An MP4 to MP3 converts files that are in the MP4 format to MP3 format. This can be helpful when a device cannot play an MP4 file and must be converted to be played.
They are the same things but I have an iPod Touch and an mp3 player but I use the iPod much more because you can have APPS on it :)
MP4 and MP3 are audio codecs that are used to encode sound into audio files. As such, in order for one to convert an mp4 file to mp3 file, they need to use a specialized software for that purpose. Alternatively, one can use media players that have that capability inbuilt.
mp3 only handles audio whereas mp4 handles audio, text, video and images
You can try mp4converter.net. I also believe that you can click to show it in windows explorer and rename it from mp3 to mp4 in the same manner that you would create a ringtone for the iphone.
Yes, MP4 players are much better than MP3 players.
You can by downloading an app on your PC/laptop then plugging your mp4 into it and downloading on your mp4. (it wont work if you have an mp3 it must be mp4)
Basically, MP3 is an audio file format, MP4 is a video file format. You can download movies onto a MP4 player and watch them back.
Neither.
An MP3 is one of the most common sound file formats currently used in digital music devices. Similarly, an MP4 is a video file format. An MP4 player generally supports both MP3 and MP4 formats, meaning that it can play both music and video. An MP3 player, unless otherwise stated by the manufacturer of the device, generally does not support the MP4 format or other video formats.
