New bit depth

Right-sizing hi-res FLAC

Much of the hi-res market ships 24-bit files whose extra resolution never survives the trip through consumer playback gear. Converting to 16-bit FLAC keeps your library lossless where it counts and visibly smaller.

The tool re-encodes to standard FLAC at the chosen depth; going up to 24-bit is also available for workflows that demand it, with the usual caveat that no new detail appears.

Frequently asked questions

Is 16-bit FLAC still "lossless"?

Yes. Lossless refers to the encoding: a 16-bit FLAC perfectly preserves 16-bit audio. Reducing depth from 24-bit discards the lowest-level information, almost all of it below audibility.

What is the size saving from 24 to 16-bit?

Roughly a quarter to a third on typical material, on top of whatever the sample rate contributes.

Does this run locally?

Yes, files are processed in the browser and never uploaded.
