uncompressible

Resists all pressure

Uncompressible describes something that cannot be compressed—squeezed into a smaller volume or reduced in size.

Liquids are nearly uncompressible, unlike gases.

The word applies literally to physical substances and figuratively to data or files that resist further compression: The archive is already uncompressible.

Incompressible is the more common variant.
