Lossless
adj.capable, thoughtfulprofessional
What it means
Preserving every part of the original information through encoding or transformation.
Reach for it when making a technical claim about exact recoverability rather than merely high perceived quality
The archive stores a lossless audio master before creating smaller listening copies.
Choose between these
6- playful
full-fidelity
product language emphasizes preservation of detail
not when Full-fidelity is a loose quality phrase, not proof of mathematically lossless recovery.
- everyday
identity with the original is the only point readers need
not when Exact is vague unless the compared representation and criterion are named.
- warm
the reproduction preserves the source's important character
not when A faithful copy may accept tiny changes and therefore need not be lossless.
- professional
bit-perfect
digital output matches the source bit for bit
not when Bit-perfect concerns one transfer or playback path, not every property of a format.
- professional
uncompressed
data remains in its direct expanded representation
not when Uncompressed files can still be altered or incomplete, and lossless compression is possible.
- formal
reversible
a transformation can be undone to recover the starting state
not when Reversibility may depend on saved metadata and is broader than information encoding.
