How to Use WAV to FLAC Converter Online

You don't need to download and install them, and their interfaces are usually user-friendly so that everyone can complete the conversion within a few minutes.

As a coin has two sides, the ease of use can also be a shortcoming of those online converters. For instance, most of them hardly have functions other than format conversion, while the desktop software can even trim the converted video/audio or adjust the sample rate freely. Online tools may suit you if you only want to get the converted FLAC file and don't need any editing tools.

Bonus Tips: WAV Format vs. FLAC Format

Making clear the difference between WAV and FLAC can help you choose the best audio format that meets your needs. This part will summarize the most typical characteristics of those two formats so that you will know them in detail.


WAV Format:

WAV is also known as Waveform Audio File Format, which Microsoft and IBM develop. Ever since its existence, WAV is taken as the format for high-quality audio reproduction. The audio contained in WAV format should stay as close as possible to the original file. This is why the WAV file size is relatively larger compared with files in other formats, and it's about 10 MB per minute.


FLAC Format:

FLAC is the abbreviation for Free Lossless Audio Codec, and it's an open-source audio format. The size of FLAC files can be reduced to half of the original audio. Surprisingly, the compression of file size will not lead to the loss of quality. In addition to audio, this format can even contain other elements like the covers and tags of songs. This feature makes it suitable to play on most music players.
