- Enter an inclusive minimum and maximum integer.
- Choose up to 100 values and whether repeated values are allowed.
- Generate the list, then copy the newline-separated result.
Secure, unbiased local selection
The generator uses crypto.getRandomValues with rejection sampling so a range is not distorted by simple modulo arithmetic. Nothing is uploaded, stored, or checked against an external service.
Bounded and predictable output
Values are limited to the signed 32-bit integer range and each request produces at most 100 lines. Unique mode cannot request more values than the available integers in the selected range.
よくある質問
あわせて知りたいこと
Are the minimum and maximum included?
Yes. Both endpoints are inclusive.
Can I generate duplicate values?
Yes. Turn off Require unique values to allow repeats. Unique mode rejects a request larger than the selected range.
Is this a cryptographic key generator?
No. It uses browser cryptography for unpredictable integers, but it is a general-purpose utility and does not provide key storage, encoding, or security review.
Does the tool send my numbers anywhere?
No. Generation runs locally in your browser and does not make a network request.
