How to use Convert Letters to Digits
- 1. Paste the text to convert. Paste a word or phrase made of letters into the input pane, ready to be converted into its A1Z26 numeric equivalent.
- 2. Set the separator between numbers. Type the character you want between each converted number into Separator, commonly a hyphen or space, to control how the output is spaced out.
- 3. Copy the converted numbers. Copy the sequence of numbers from the output pane, where each letter became its alphabet position, and paste it wherever a numeric cipher output is wanted.
When to use Convert Letters to Digits
Convert Letters to Digits replaces each letter with its position in the alphabet, so a becomes 1 and z becomes 26, a scheme known as A1Z26. Use Convert Letters to Digits for building or solving simple number-substitution puzzles.
- Building an A1Z26 puzzle clue. A scavenger hunt or escape room clue needs a word encoded as alphabet positions, and converting the answer here produces the numeric sequence for players to decode.
- Demonstrating a basic numeric cipher. Teaching how letter-to-number ciphers work is clearer with a working example, and converting sample words shows students exactly how each letter maps to its position.
- Encoding a short phrase as a number sequence. You want to lightly disguise a short phrase as a series of numbers for a puzzle or game, and this handles the letter-to-number conversion in one step.

About the Convert Letters to Digits tool
Convert Letters to Digits is a free online tool that works entirely inside your web browser. Replace each letter with its position in the alphabet (a=1 … z=26). Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 211 Text utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with the Separator setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Convert Letters to Digits free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?

How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
