Generate secure random strings and UUID v4 values
Use browser cryptography to generate random strings and UUID v4 values locally, with preset or custom lengths, batch output, character sets, and ambiguity controls.
Flexible character sets
Combine lowercase, uppercase, numbers, symbols, and custom characters, with optional removal of oO0iIlL1.
Strings and UUIDs
Generate preset strings from 8 to 128 characters, custom lengths, or standard UUID v4 values in batches.
Random string and UUID generator FAQ
Are generated values uploaded?
No. Random strings, UUIDs, and settings stay in the current browser page.
Why exclude ambiguous characters?
Characters such as o, O, 0, i, I, l, L, and 1 can look alike in many fonts and are harder to enter manually.
Can I use the strings as passwords?
The generator uses browser cryptography, but passwords should still be unique for every account and stored in a trusted password manager.
