Transform yourself into a cartoon with ToonMe – Cartoon Face Maker. Available for free on the Google Play Store, ToonMe – Cartoon Face Maker features four face maker modes: Cartoon, 3D, Angel Face, and Game Face. The cartoon mode transforms your photo into a retro-style illustration, reminiscent of the art style used in comic books. The 3D mode, on the other hand, makes your eyes look bigger like a cute anime character. 

The Angel Face mode improves your overall appearance by making your face clearer and more cherubic. Your hair also becomes blonde if you choose this mode. But if becoming an angel is not your cup of tea, then Game Face may be perfect for you. Game Face turns you into a gorgeous NPC — delicate lips, bright eyes, and baby-faced. Whichever mode you choose, you’ll never get bored of using ToonMe – Cartoon Face Maker.
