An adjective meaning 'global' or 'worldwide'. It can imply world-class when context makes it clear, but it's broader and can just mean 'international'. Use with care.

Emphasizing that something is among the very best, elite, or first-rate in the world.

Literally 'world's highest peak', a metaphorical phrase for the absolute best. Dramatic and often used in writing or speeches.
世界レベルの explicitly means 'world standard/level' and implies high quality. 世界的な means 'global/international' and does not necessarily imply top quality. Use 世界レベルの when you mean 'world-class' in the sense of excellence.
a global company (not necessarily top-tier)
a world-class company (top-tier)
The direct translation '世界クラス' (sekai kurasu) is sometimes used in Japanese, but it's a loanword and can sound unnatural or like marketing jargon. Stick to native phrases like 世界レベル or 一流 unless you are sure of the context.
