Welcome to UtilityTools — a collection of free, fast, and privacy-respecting online tools. Every tool on this site runs entirely in your browser with no registration, no installation, and no data sent to any server. Choose from our growing suite of utilities below.
Unlike most utility tool sites, we don't require registration, we don't send your data to servers, and we don't clutter the interface with popups. Every tool is free, fast, and private. Your passwords are generated locally, your QR codes are rendered in your browser, and your text is processed on your device.
We also publish comprehensive guides to help you understand the technology behind our tools: How to Create a Strong Password, Password Security Best Practices, What is a QR Code, and QR Code Use Cases for Businesses. Visit our Guides menu to explore them.
Our free password generator creates strong, secure passwords instantly in your browser. No registration, no installation, and no data sent to any server. Every password is generated locally using the Web Crypto API for cryptographically secure randomness.
1. Choose a preset — Select from Website Password, WiFi Password, PIN Code, or Passphrase modes.
2. Adjust the settings — Set the password length and choose which character types to include (uppercase, lowercase, numbers, symbols). You can also exclude similar-looking characters like l, 1, O, and 0.
3. Generate — Click the generate button to create a new password. Each click produces a completely unique password.
4. Copy — Click the copy button to copy the password to your clipboard, then paste it into your password manager or wherever you need it.
A strong password has three key properties: length, randomness, and complexity. Length is the most important factor — a 16-character password with only lowercase letters is stronger than an 8-character password with every character type. Randomness means the password cannot be predicted or guessed. Complexity means using a mix of uppercase letters, lowercase letters, numbers, and symbols to increase the number of possible combinations.
Our generator shows the estimated crack time for each password, so you can see exactly how secure your password is. A password with a crack time of "centuries" is considered very strong for personal use.
A random password is a string of random characters like K7$mP2x!nQ9vLw. It's highly secure but hard to remember. A passphrase is a sequence of random words like correct-horse-battery-staple. It's easier to remember and type while still being very secure due to its length. Our generator supports both modes.
Yes. Our password generator uses the Web Crypto API, which provides cryptographically secure random number generation directly in your browser. The passwords are generated entirely on your device and never sent to any server.
No. Every password is generated locally in your browser using JavaScript. We have no server-side component that handles passwords. We cannot see, store, or recover any password you generate here.
For most online accounts, we recommend at least 16 characters with a mix of uppercase, lowercase, numbers, and symbols. For highly sensitive accounts like banking or email, consider 20+ characters or a 5-6 word passphrase.
Crack time is an estimate of how long it would take a powerful computer to find your password through brute force — trying every possible combination until it finds the right one. A crack time of "centuries" means it would take hundreds of years to crack, which is considered very secure.
Yes, strongly recommended. A password manager securely stores all your generated passwords so you only need to remember one master password. Popular options include Bitwarden (free and open source), 1Password, and KeePass.
