What does lossiest mean?
Lossiest is the superlative form of lossy, an adjective meaning that some information or quality is lost during processing, transmission, or storage. It identifies the option, format, or process that involves the greatest such loss. Lossy compression is common for images, audio, and video because it can produce substantially smaller files by discarding information that human listeners or viewers may barely notice. The lossiest choice is therefore often a practical trade-off rather than the best choice for absolute fidelity. In contrast, a lossless process preserves the original data exactly. The word is especially common in computing, telecommunications, digital media, and audio engineering, where settings for compression, encoding quality, bandwidth, and file size are routinely compared. Outside technical contexts, it is less usual and may sound deliberately precise or humorous.
adjectiveHaving the greatest loss of information or quality. In technical contexts, “lossy” describes a process that discards or reduces some data, and “lossiest” identifies the process with the greatest such loss.

"The lossy format produced the smallest files but gave the lossy option the highest compression."
"We selected the lossiest preset to keep the live broadcast stable despite a limited connection."
"Although it is the lossiest codec, it remains suitable for voice messages."
The lossiest option may look or sound worse, but it can be the best choice when bandwidth, storage, or processing speed matters more than perfect fidelity.

Where does lossiest come from?
“Lossiest” is formed by adding the superlative suffix -est to lossy. The adjective lossy was created from loss with the suffix -y, while loss ultimately comes from Old English lāss, an ancestral form related to lose and less. The technical sense arose with the development of lossy data compression and related methods in the twentieth century.

This is chiefly a technical term used in computing, media encoding, and telecommunications. It is usually predicative, as in “the lossiest setting,” rather than placed directly before a noun.
Easily confused with lossiest
Lossless compression preserves all the original data, whereas lossy compression discards some information to reduce file size or processing requirements.
