Cryptogram Maker

About this worksheet maker

A cryptogram turns reading into a friendly puzzle: each letter is hidden behind a little picture or symbol, and children crack the code to reveal the words. This free cryptogram maker lets a teacher build one in under a minute — choose a theme, type the words you want, and the page sets up the picture key and the coded message for you.

Because you choose the words, the puzzle can match exactly what your class is learning — this week's spelling list, vocabulary from a story, or names from a topic. The generator draws on a library of more than 3,000 themed pictures, so the symbols feel inviting rather than abstract for early readers.

Everything prints cleanly as a worksheet, and an answer key prints alongside it. There is no account to create and nothing to install — it runs in the browser, works in 11 languages, and the finished puzzle is completely free to use in your classroom.

How to use it in class

• Pick a theme and type the words or short message you want children to decode.
• Print the worksheet and hand out the picture key so children can match each symbol to its letter.
• Let children work in pairs to crack the code, decoding one word at a time.
• Use the answer key to check the solution together at the end.
