Solve Cryptograms with Our Online Solver

Cryptogram Solver is like your personal cipher buddy, it reads the jumbled and cryptic message, looks at how often each letter shows up, and tries out substitutions the same way you’d do on paper, just at lightning speed. Whether you call it a Cryptogram Solver, Cipher Solver, Code solver, or Substitution Cipher Solver, it’s all the same mission.

Paste or Upload any cryptoquip, cryptoquote, or random cipher text. The tool takes a first shot using letter frequencies, then you can tweak the substitution map, if hints or clue like “A=E,” or paste known words to which helps it generating the answer and crypic keys.

This tool is free, fast, and private because the solver runs right in your browser, no sending data over the internet. No puzzles, clues, or secreat ideas leave your device.

You can pick the solving mode that fits your puzzle:

  1. Adaptive – the default option hassle free solving mode.
  2. Pattern & Dictionary – perfect for quote styled cryptoquips where repeated alphabets matter.
  3. Frequency & Statistics – better for long patristocrats or cipher texts without spaces.
  4. Hybrid – mixes both strategies if you want the solver to try everything at once.

Quick Start

  • Paste the cipher text into the input box.
  • Hit “Auto Solve” to let the cipher solver guess the first few letters.
  • Edit the substitution map or use the hints box when you spot obvious matches.
  • Check the frequency panel to see which letters behave like E, T, or A.
  • Download or copy the finished message once you’re happy with the result.

How this Cryptogram Solver works?

  1. Count the letters. If J shows up a ton, it might be E or T.
  2. Test patterns. “XFFU” has the same shape as “BALL,” so it tries X=B and F=L.
  3. Check real words. It keeps swapping letters until actual phrases appear.
  4. Fill the blanks. Any unmapped letter shows as “•,” so you know where to focus next.

So whether you call it a cipher cracker or a cryptoquip solver, the goal is simple: solve the cryptogram without losing your weekend.
