About Pseudo-Random Integer Generator
A cryptographically-secure pseudo-random number generator (PRNG). Generates random integers within a specified range using the browser's built-in crypto.getRandomValues() method if available. The supported range of integers is from -(2^53 - 1) to (2^53 - 1).
Input: text. Output: text.

Before interpreting the result
These tools have specialized conventions. Read the operation description and parameter choices before interpreting the result.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
