Password Generator

Generate strong, secure random passwords

UUID Generator – Create UUID v4 Online

Generate one or multiple random UUID v4 identifiers. Choose uppercase or remove hyphens, then copy the list for application records and test data.

Hash Generator – MD5, SHA-1 and SHA-256 Checksums

Calculate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes for text or a file. Copy hexadecimal checksums and compare them with your reference value.

Fake Data Generator – JSON and CSV Test Data

Generate up to 100 sample records with names, emails, addresses or business data. Copy the results or export JSON and CSV for development and testing.

Base64 Encoder and Decoder for Text and Files

Encode text or a file as Base64, or decode a Base64 string to text. Copy the result directly from your browser. Base64 is encoding, not encryption.

Generator FAQ

Are generated passwords cryptographically secure?

Yes, our password generator uses cryptographically secure random number generation (CSPRNG) from the Web Crypto API. You can customize length, include symbols, numbers, and mixed case. Passwords are generated locally in your browser for complete security.

What QR code types can I generate?

We support QR codes for plain text, URLs, email addresses, phone numbers, SMS messages, WiFi credentials, vCards, and more. You can customize error correction levels, size, and colors. Generated QR codes are high-resolution and downloadable as PNG or SVG.

Can I generate multiple UUIDs at once?

Yes, our UUID generator can create single or bulk UUIDs (Version 4) with one click. Each UUID is guaranteed to be unique using secure random generation. Perfect for database seeding, API testing, and generating unique identifiers for applications.
