Free Cryptogram Maker — Generator & Online Solver

A cryptogram is a short piece of text encrypted with a simple substitution cipher — each letter of the alphabet is swapped for a different letter consistently throughout the message. Your job as solver is to figure out the mapping and decrypt the original phrase.

Enter any phrase, choose a difficulty level, and our generator creates a random A-Z substitution cipher. You get a printable PDF with the encrypted puzzle and a separate answer key, plus an interactive online mode where you can type your guesses.

Easy reveals the 3 most common cipher letters up front — great for kids and beginners. Medium reveals just 1 letter as a starter hint. Hard gives you nothing but the encrypted text — for seasoned puzzle solvers who love the challenge.
