Free Random Number Generator for Mobile & Desktop

A random number generator is a multipurpose tool used in gaming, data analysis, simulation, and computer security. It is established to create random outcomes that make it important for fair draws, secure systems, and accurate modeling.
In this post, we’ll explain what numbers and random number generators are, how our free tool works, and why it’s useful.

What is a Number?

A number is the basic unit of mathematics that is used for counting, measuring, and comparing. Numbers are necessary for organizing our perspective of the world in measuring time, costs, or simply working with underlying numerical data. Numbers can exist in several different types: integers (1, 2, 3), decimal fractions (3.14), and negative values (-5).
In our context of random number generation, they also determine the range of numbers from which values will be pulled. They’re the foundation of any random number generation tool.

What is a Random Number Generator​?

A Random Number Generator can operate as either a software-based or hardware-based tool that produces numbers in a non-patterned manner. These numbers are selected entirely at random and are beneficial for fair uses, unpredictable scenarios, or to mimic random processes.
There are two primary categories of Random Number Generators:
True Random Number Generators (TRNGs): These utilize physical effects (such as radioactive decay or atmospheric noise) to create randomness.
Pseudo-random number Generators (PRNGs): These apply mathematical formulas and algorithms to produce sequences of numbers that seem random.
Most online tools, including ours, uses high-quality PRNGs that are more than sufficient for everyday tasks like games, decisions, and general use.

How can You Use Our Free Online Random Number Generator?​

Step 1: Open Random Number Generator​.
Step 2: Set Your Range: In the “Range Start” field, enter the lowest number you want (e.g., 1), and in the “Range End” field, enter the highest number you want (e.g., 100).
Step 3: Choose Quantity: Under “How many numbers to generate?”, input how many results you want, whether it’s 1, 10, 50, or more.

Step 4: Choose between:

  • Generate Random Whole Numbers – for integers like 15, 42, 99.
  • Generate Random Fractional Numbers – for numbers with decimals (e.g., 45.12345).
If you choose fractional, you can control how many decimal places you want under “Fraction precision” (e.g., 5 for five digits after the decimal).

Step 5: Choose Output Format: In the “Which character to separate numbers with?” field, define how the results are formatted:

how the results are formatted:

  • Use “n” (newline) for a vertical list.
  • Use “,” (comma) or a space to get a horizontal row.
Step 6: Click “Generate Random Number” to generate your random numbers instantly.
Step 7: Either you can copy the data or download the TXT file on your device.
