A good incredible synonym begins with a choice between two ideas: wonderful, or hard to believe. For praise, reach for amazing, extraordinary, remarkable or phenomenal. For doubt, unbelievable and far-fetched do the work.
The word comes from a Latin root meaning not believable, and that old sense still lives on in phrases like an incredible excuse. Most people today use it as a loud compliment, though, and that is where writers tend to overuse it. Below, every useful option is grouped by meaning, shows how strong each one feels and offers ready swaps for the line you are stuck on.

Ranking the praise words by volume
Think of a dimmer switch, turned up one notch at a time. Impressive is a calm nod of approval. Remarkable says something deserves comment. Extraordinary puts it outside the normal range. Astonishing adds surprise, and phenomenal is close to the top of the dial.
Casual speech has its own loud set: awesome, mind-blowing and insane. Friends will not blink at them, yet a teacher grading your essay probably will.

Essay, review or group chat
Academic writing: incredible often reads as gushing. Use remarkable, exceptional or striking, then prove the claim with numbers. A remarkable rise of forty percent says more than an incredible rise.
Reviews and travel posts: breathtaking fits scenery, stunning fits looks, and wonderful fits a whole experience.
Texts and chat: amazing, unreal and mind-blowing match the energy most people use there.
Near misses to avoid
Swap hunters chasing another word for incredible often grab incredulous. That is a mistake. It looks similar but describes a person who does not believe something: she gave an incredulous laugh. It never means amazing. Unbelievable works for both praise and doubt, so check that your sentence cannot be read the wrong way. Fabulous once meant like a fable, but today it is just cheerful praise and carries no hint of doubt.
For the adverb, as in incredibly hard, see incredibly synonyms: extremely, remarkably and exceptionally.
