Create strong, cryptographically random passwords locally in your browser with complete control over length and characters.
Generated locally with cryptographic randomness. Nothing is transmitted or stored.
Entropy is an estimate based on length and the selected character pool. For important accounts, use a unique 16+ character password and enable multi-factor authentication.
OptimizeFile never sends, saves or logs generated passwords. Copy the result into a trusted password manager before leaving this page.
Use at least 16 characters for important accounts whenever the website allows it.
Mix uppercase, lowercase, numbers and symbols, or adjust advanced rules for strict forms.
Create a fresh password, copy it and store it in a trusted password manager.
Passwords are created with the browser Web Crypto API and uniform random selection. Every enabled character type is guaranteed to appear in the result.
Generation happens in your browser tab. Passwords are not uploaded, saved, logged or included in the page URL.
Yes. The generator uses crypto.getRandomValues instead of predictable pseudo-random methods such as Math.random.
Sixteen or more random characters is a strong default. Use the maximum length supported for high-value accounts.
Characters such as 0, O, 1, l and I can look alike. Excluding them makes manually typed passwords easier to read.
No. Passwords exist only in your browser tab and are never sent to an OptimizeFile server.
No. Use a unique password for every account and save it in a trusted password manager.
