MP3 –

MP3 stands for MPEG-1 Audio Layer 3. It was designed by Moving Picture Experts Group. MP3 is largely used worldwide for audio streaming or storage. It’s an audio coding format that largely reduces amount of data required for audio recording due to use of MP3 compression technology.

File size in case of MP3 is lower and has no fixed compression ratio. Thus one can have different file sizes with different quality of audio. Another advantage with mp3 is that they can work with almost all type of musical devices. However the major disadvantage i is that it is a low quality audio and it can play only audio.


MP4 –

MP4 stands for MPEG-4 Part 14. It was designed by International Organization for Standardization. MP4 is a digital format that is largely used worldwide to record both audio and video. It takes lot of disc space and its compression technology is complex too. However ,they can handle texts and images too.

MP4 is a new technology capable of handling all audio, videos, images and texts as well. Files in this format are of high quality and compression in this format is done without any loss. Nowadays with the growing trend of mobile phones, for video websites like youtube, MP4 is the most compatible and used format.

The choice simply depends on what an individual wants at that moment. If he wants to listen to audio songs only, MP3 is the way to go, as it allows you to keep more number of files in the limited disk space. And if you want to view video, images text, than you have no option other than to choose MP4 format.

Key differences 

MP3 stands for MPEG-1 Audio Layer 3. (MPEG – Moving Pictures Expert Group) MP4 stands for MPEG-4 Part 14.
It can play only audio files. It can handle videos, audio, text, images – almost everything.
Compression of file in this format leads to loss of original audio quality. There is no such loss. Thus if you want to hear loss less audio quality, than choose MP4.
Disk space (storage) taken up by a MP3 is less as compared to MP4. MP4 occupies more disk space than MP3.
They can be played in almost all type of music playing instruments. They can’t be played on every device.
It is an older technology, designed by Moving Picture Experts Group. It is new technology designed by International Organization for Standardization
It has no fixed compression ratio. It has fixed compression ratio.
MP3 playing devices are cheaper. These devices are costly.



MP3 file format is used to run only audio files while the MP4 format supports all videos, audio, text and images. The choice between MP3 and MP4 depends on what the user desires. If you want to keep lots of audio files in your device, than MP3 is the obvious choice (due to its lower file size). And if you wish to hear the audio in loss less original audio quality than one should go for MP4. In case if you want to watch video, images, audio and texts too than you have no option other than to go for MP4.
