A WAV file is also known as a WAVE file and is a lossless audio file. This means the file has high-quality audio, making it a popular choice for music experts, such as audio and sound engineers. The large files sizes resulting from the quality audio are the only drawback to this file type, but it’s a format that’s been around for decades and stood the test of time.

An MP3 file is a compressed audio file that saw an explosion in use with the birth of the Apple iPod and the creation of rival MP3 players that allowed people to play music on the go. Files were small in size and still fairly high in quality, meaning it was one of the most popular file formats in the early 00s. Over time, however, more efficient audio formats have taken its place, and its popularity has waned.

Frequently Asked Questions

How do I convert WAV to MP3?

The easiest way is to use an online conversion tool, such as Zamzar. Simply upload the WAV file, select MP3 as the format you want to convert to, and click 'Convert Now'. The file will then be converted in real time, without the need to download any software.

How do I convert multiple WAV files to MP3?

Zamzar allows you to convert two files concurrently for free, but with a paid account allows you to convert up to 100 files in one batch.

Is WAV better than MP3?

WAV files have not been compressed and tend to be high in quality, but are also large in terms of the amount of storage space that they take up. MP3 files are lower in quality, albeit still perfectly good for listening to music and other forms of audio. Importantly, they’re about a tenth of the size of a WAV file, and so are a lot more portable; this means they tend to be more widely used.

What are the disadvantages of WAV?

A WAV file can be prohibitively large in size – ten times larger than an MP3 file. This makes sharing and storing WAV files particularly challenging. If a WAV file has been converted to a compressed file format and then later converted back to a WAV file, then the original audio quality of that WAV file would have been lost.

Can Windows Media Player convert WAV to MP3?

Yes, is the simple answer. Simply right-click on the WAV file and select 'Open with Windows Media Player'. Once launched, click the 'Organise' button in the menu at the top. Next, click the menu item that says 'Options', followed by 'Rip Music'. Select the desired file location to save the file to, and select 'MP3' in the 'Format' section, under 'Rip settings'. Finally, click 'Apply', followed by 'Ok', and that’s how you can convert a WAV file to an MP3.
