Generator Hub

Generate QR codes, strong passwords, random numbers, and Lorem Ipsum text. Multiple generators in one place.

Your data never leaves your browser — nothing is sent to any server.

How to use
  1. 1

    Choose a generator

    Select from QR Code, Password, Random Number, or Lorem Ipsum using the tabs.

  2. 2

    Configure options

    Each generator has customization options: QR content, password length and character types, number range, or paragraph count.

  3. 3

    Generate

    Results generate automatically as you type or change settings. Use the Regenerate button for a fresh result with the same settings.

  4. 4

    Copy or download

    Copy results to clipboard or download QR codes as PNG images. All generation happens in your browser — nothing is sent to a server.

FAQ (6)
How do I generate a QR code?

Enter any text, URL, email address, phone number, or Wi-Fi credentials in the QR Code tab. The QR code generates instantly and can be downloaded as a PNG image. The generated QR code works with any standard QR code scanner.

What makes a password 'strong'?

A strong password is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. The strength indicator evaluates length and character diversity. Passwords generated here use cryptographically secure randomness (Web Crypto API), making them suitable for all accounts.

Are the generated passwords stored anywhere?

No. Passwords are generated entirely in your browser using the Web Crypto API. Nothing is sent to any server. Once you close or refresh the page, the generated password exists only if you've copied it to your clipboard or saved it in a password manager.

What is the maximum QR code content length?

QR codes can store up to approximately 4,296 alphanumeric characters or 2,953 bytes of binary data. However, longer content produces denser QR codes that may be harder to scan with older devices. For URLs, keeping content under 500 characters ensures reliable scanning.

How does the random number generator work?

Enter a minimum and maximum value, choose how many numbers to generate (up to 100), and click Generate. Numbers are uniformly distributed within your range using Math.random(). For non-cryptographic purposes like games, lotteries, or statistical sampling, this provides good randomness.

What is Lorem Ipsum used for?

Lorem Ipsum is placeholder text used in design and development to fill space before real content is available. It has a roughly normal distribution of letters and words, making it look like readable English without distracting reviewers with meaningful content. It's been the industry standard since the 1960s.

Generator Hub: QR Codes, Passwords, and More

The Generator Hub combines the most commonly needed generators into a single tool. Create QR codes for URLs and text, generate cryptographically strong passwords, produce random numbers for any range, and create Lorem Ipsum placeholder text — all running entirely in your browser with zero server dependencies.

QR Code Generator

QR (Quick Response) codes encode text, URLs, contact information, Wi-Fi credentials, and more into a 2D barcode scannable by any smartphone camera. This generator produces standard QR codes following the ISO/IEC 18004 specification with error correction level M (recovers up to 15% damage). Output is a clean PNG image at 300×300 pixels, suitable for print materials, presentations, business cards, and digital displays.

Password Generator

Weak passwords remain the leading cause of account breaches. This generator creates passwords using the Web Crypto API's cryptographically secure random number generator — the same entropy source used by password managers like 1Password and Bitwarden. Each character is independently selected from your chosen character set with uniform probability, eliminating patterns that attackers exploit.

Password Strength Guidelines

NIST SP 800-63B recommends passwords of at least 8 characters, but 12–16 characters with mixed character types provides substantially better security. A 16-character password using uppercase, lowercase, numbers, and symbols has approximately 105 bits of entropy — requiring 2^105 guesses in a brute-force attack, which is computationally infeasible with current and foreseeable technology.

Random Number Generation

Generate random integers within any range for use in games, statistical sampling, lottery simulations, A/B test group assignment, or any scenario requiring non-deterministic selection. The generator uses uniform distribution, meaning every number in your specified range has an equal probability of being selected.

Lorem Ipsum Placeholder Text

Lorem Ipsum has been the typesetting industry's standard dummy text since the 1500s. Its pseudo-Latin text has a natural letter frequency distribution that closely resembles English, making it ideal for previewing typography, testing layouts, and filling content areas during design. This generator produces randomized paragraphs that avoid the repetitive patterns of the classic "Lorem ipsum dolor sit amet" opening.
