All random number generation occurs in your browser — no data sent to any external server.
Set any minimum and maximum values including negative numbers, with support for very large ranges.
No cost, no accounts, no usage limits — generate all the random numbers you need without restrictions.
Generate integers, decimals with configurable precision, or whole numbers based on your requirements.
Every TextCraft tool processes your data entirely in your browser — nothing is uploaded to any server. This means your files, text, and personal information stay completely private on your device. Whether you are converting documents, editing images, or generating random data, you can work with confidence knowing your content never leaves your computer.
Standard random functions like Math.random use pseudo-random number generators that are predictable given enough observations. Cryptographic random generation uses the Web Crypto API which draws entropy from system-level sources, producing numbers that are truly random and unpredictable. This makes cryptographic randomness essential for security, gambling, and scientific applications where predictability is unacceptable.
Yes, you can configure the decimal precision from zero (integers) up to several decimal places. This allows you to generate numbers like random prices with two decimal places, precise measurements with three decimals, or any other precision requirement. The rounding follows standard mathematical conventions for accurate and predictable results.
The tool supports a very wide range limited primarily by JavaScript number precision. You can specify ranges spanning billions or more, from negative to positive values. For most practical applications including giveaways, education, and testing, the range is effectively unlimited and accommodates even the most demanding numerical requirements.
The cryptographic random generation combined with proper mathematical range mapping ensures perfectly uniform distribution. Every value between the minimum and maximum has exactly equal probability of being selected. This uniform distribution is mathematically verified and essential for applications requiring unbiased random selection like scientific sampling and fair contests.
The standard generation mode includes all values within the specified range. Some implementations offer exclusion lists or skip patterns that let you omit specific numbers. This is useful for scenarios like generating random room numbers while excluding already-occupied rooms, or creating random IDs without reusing previously assigned values.
