What Mirror a Number can do:

This tool takes every line of input and reverses the order of its digits. For example, if you type 123, it outputs 321. It works on full lines, so if you enter multiple numbers on separate lines, each one gets mirrored independently.

It also includes a live output counter that tracks how many lines were processed. The interface is fast, clean, and designed to handle simple text-based inputs with no extra fuss.

Example:

Input:

1234
908172

Output:

4321
271809

Common Use Cases:

Use this when creating mirrored numeric patterns, practicing logic puzzles, developing test data for number input validation, or just for fun. It’s a small utility that helps you reverse numbers quickly without needing to open a spreadsheet or write a script.

Useful Tools & Suggestions:

If you’re flipping numbers visually, Reverse a Number is a natural complement it just inverts the digit order. And if you want to take that mirrored result further, Change Number Font lets you style it in bold, circled, or even fullwidth for extra impact.
