Upload a FLAC file, choose an output such as 3GP, AAC, AIFF or ALAC, and download the result. FLAC compresses audio losslessly, typically to around half the size of WAV, with every sample preserved.
A FLAC source is losslessly compressed audio that preserves decoded samples and supports rich tags. Its useful destination depends on which stored properties the receiving workflow actually consumes.
Files in the same family often need similar handling, so compare the Waveform Audio conversion options and the ways to convert OGG files.

Confirm the specific program, device, or platform on the other end before picking an output format.
The codec, sample format, bitrate, channels, and metadata all change during audio conversion, sometimes invisibly. What counts as an acceptable result differs for a studio master, a delivery copy, and plain speech.
losslessly compressed audio that preserves decoded samples and supports rich tags
FLAC does not make a lossy source lossless again, and some basic players reject less common sample rates or channel layouts.
Compare duration, sample rate, channels, peak levels, and tags with the decoded source.
