What does uncompressed mean?
Uncompressed describes something that has not been compressed, meaning it remains in its original or expanded form rather than being made smaller by applying pressure, condensing material, or encoding data more efficiently. The word is especially common in computing and media: uncompressed audio, images, files, and data retain their full original form, often with greater quality and size. In everyday contexts, it can refer to anything that has not been packed, squeezed, or condensed, such as an uncompressed bundle. Its meaning is generally neutral, although it may suggest that a file occupies more space or that compression has deliberately been avoided. The adjective is useful when distinguishing original material from a compressed copy, particularly when fidelity, immediate access, or further editing matters.
adjectiveNot compressed; existing in its original, uncondensed, or unpacked form. In computing and media, describing information or files that have not been reduced in size through compression.
- Not compressed; in its original, uncondensed, or unpacked state.
- In computing and media, not reduced in size through compression.
"The archive contains uncompressed images, so the photographs retain every original detail but take up considerably more space."
"Keep an uncompressed copy of the master recording in case the lossy compressed version loses important detail."
"The shipment arrived in an uncompressed bundle, making it much larger than the packaged product."
Uncompressed is what a file looks like before compression gives it a smaller digital wardrobe.

Where does uncompressed come from?
Uncompressed is formed in English by combining the prefix un- with compress. Compress comes through Old French from Latin comprimere, meaning “to press together.” The prefix reverses the effect of compression, producing a word widely used for material, files, images, and audio that have not been reduced in size.
How uncompressed is actually used
The term is especially common in computing, media production, and data storage. It is neutral and technical rather than evaluative, though it can imply increased file size or reduced processing efficiency.
