Generate QR codes, strong passwords, UUIDs, and placeholder text on demand for projects, docs, and product labels. Hash strings with common algorithms and check password strength before you commit to a credential. Every generator works entirely in your browser, so nothing you create is stored or tracked.
Generate custom QR codes for URLs, Wi-Fi, contacts, and more. Customize colors and size.
Create strong random passwords with customizable length and character sets.
Generate UUID v4 and v7 identifiers with customizable output format.
Generate placeholder text by paragraphs, sentences, or words.
Compute SHA-256, SHA-512, SHA-1, and MD5 hashes in your browser.
Analyze passwords with entropy, crack time, and improvement tips.
Our generator tools help you create everything from QR codes and passwords to UUIDs and placeholder text. Every tool runs entirely in your browser — no data is sent to any server. This ensures that sensitive data like passwords and API keys never leave your device.
Whether you need a QR code for a business card, a strong password for a new account, or lorem ipsum for a design mockup, these tools give you instant results without any setup, sign-up, or installation required.
Each generator serves a specific purpose. Here's how to pick the right one:
Security is built into every generator. Passwords use the browser's cryptographic random number generator (crypto.getRandomValues) for true randomness, not predictable pseudo-random algorithms. UUIDs follow the RFC 4122 standard. Hash computations use the Web Crypto API. All generation happens locally — nothing is transmitted, logged, or stored.
