Do I need 3-phase for a workshop compressor?

Only above about 4kW (18+ CFM). Single-phase 240V handles most small workshops just fine.

Can I run a 3-phase compressor on single-phase?

Only with a variable-frequency drive (VFD) converter — adds cost and complexity. Better to spec the right voltage from new.

Are 3-phase compressors more efficient?

Yes — they typically run 10–20% more efficiently per CFM and last longer thanks to lower motor current per phase.

3-phase (415V) air compressors deliver more power per amp than single-phase units, run cooler and last longer under sustained load. They're the industrial standard above 4kW.
