14 Best Free Online AIFF to FLAC Converter Websites

Here is a list of best free online AIFF to FLAC converter websites. AIFF (Audio Interchange File Format) is a type of audio file format that stores high-quality audio data. It is mainly used in personal computers to store and play audio information. On the other hand, FLAC (Free Lossless Audio Codec) is another common audio file format that stores audio information similar to AIFF. Plus, it is also a lossless audio format just like AIFF. At times, it is necessary to convert one audio format to another as audio applications don’t support all types of audio formats. To rectify the compatibility issues, users need to convert an incompatible audio format to a compatible audio format like AIFF to FLAC. If you also want to do that, then check out these AIFF to FLAC converter websites.

Through most of these converters, users can batch-convert multiple AIFF files to FLAC at a time. Although, some converts can only process one audio file at a time. Besides AIFF and FLAC, most of these converters also support MP3, WMA, AAC, AC3, WAV, ALAC, etc., audio formats. On some converters, users also get the ability to manually adjust the output audio parameters like Audio Quality, Volume, Audio Sample Rate, Channels, etc. I have also included the steps of AIFF to FLAC conversion in the description of each website. Go through the list to know more about these converters.
