For fitting a lossless library onto limited storage, nothing beats Opus. Encoded from FLAC at 128 kbps, tracks land around a megabyte per minute and remain transparent for most listeners; MP3 needs more than double the space for the same confidence. The trade is ecosystem: Android and dedicated player apps handle OGG happily, Apple's defaults do not. Conversion here is local, with the bitrate adjustable between 64 and 192 kbps.
Questions
How does Opus at 128 compare to MP3 at 320?
In listening tests they are comparably transparent; Opus achieves it in 40 percent of the bytes because it is a far newer design.
Why keep the FLACs then?
Because Opus is a delivery copy. The lossless originals let you re-encode when formats or preferences change, at zero quality cost.
What breaks with OGG files?
Mostly Apple defaults and older car head units. Test one file on your actual devices before converting hundreds.
Where does encoding happen?
In your browser. The library stays yours alone.
