Free Online Generator Tools

What Each Tool Does

Every tool below opens instantly, needs no account, and processes your data locally in your browser. Here is what each one is for:

Password

Strong random passwords with control over length, symbols, digits and ambiguous characters — generated with cryptographic randomness, locally. Open the Password →

QR Code

Turn any link or text into a crisp, downloadable QR code with adjustable size and error correction. Open the QR Code →

Random Number

Random numbers in any range, one at a time or in batches, with or without repeats — dice for grown-ups. Open the Random Number →

UUID

Generate RFC-compliant v4 UUIDs, singly or in bulk, ready for databases and APIs. Open the UUID →

Hash

Compute MD5, SHA-1, SHA-256 and other digests of any text — verify integrity or generate checksums instantly. Open the Hash →

Color Palette

Generate harmonious color palettes with hex codes you can copy straight into your design or CSS. Open the Color Palette →

Fake Data

Realistic fictitious names, emails, addresses and more for populating test databases and design mockups. Open the Fake Data →

Slug

Convert titles into clean, lowercase, hyphenated URL slugs, handling accents and punctuation properly. Open the Slug →

CSV to JSON

Paste CSV data and get well-formed JSON out (and back) — the quickest bridge between spreadsheets and code. Open the CSV to JSON →

Fibonacci

Generate Fibonacci sequences to any length — for math class, algorithms practice or curiosity. Open the Fibonacci →

Factorial

Compute factorials, even large ones, without overflowing your pocket calculator. Open the Factorial →

Username

Fresh username ideas from styles and themes you pick — for gamertags, handles and new accounts. Open the Username →

Credit Card

Luhn-valid test card numbers for payment-form development and QA — fictitious and safe by design. Open the Credit Card →

IP Address

Random IPv4 and IPv6 addresses for network testing, documentation and mock data. Open the IP Address →

Acronym

Build pronounceable acronyms from a phrase — name your project something you can actually say aloud. Open the Acronym →

Privacy Policy Generator

Answer a six-step wizard and get a complete, customized privacy policy — GDPR and CCPA sections included — ready to publish. Open the Privacy Policy Generator →

UTM Builder

Build correctly encoded campaign tracking URLs with utm_source, medium and campaign, with live preview and one-click copy. Open the UTM Builder →

How to Choose the Right Tool

For security, the Password Generator creates strong random passwords and the Hash Generator computes MD5, SHA-1 and SHA-256 digests. Developers lean on UUID, Fake Data, IP Address and Credit Card generators for test fixtures (test numbers are for development only). The QR Generator turns links and text into scannable codes; the UTM Builder tags campaign links for analytics; and the Privacy Policy Generator walks you through a wizard and outputs a publishable policy. For creative work, grab the Color Palette generator; for writing and naming, the Slug, Username, Acronym, Lorem-style and number generators (Random Number, Fibonacci, Factorial) cover the rest.

Frequently Asked Questions

Are the generated passwords safe to use?

Yes — passwords are generated locally using your browser's cryptographic random number generator and never leave your device.

Are the credit card and personal data generators real data?

No. They produce mathematically valid but fictitious test data for developers — the numbers cannot be used for real transactions.

Do QR codes generated here expire?

No. The QR code encodes your content directly, with no intermediary service, so it works as long as the destination exists.

Is anything I generate stored on a server?

No. All generation happens in your browser; WiserWork never sees your passwords, policies or campaign links.
