Generator Tools

Free online generators for UUIDs, QR codes, barcodes, passwords, and more

Generating identifiers, codes, and placeholder content is a daily task for developers, designers, and operations teams. The challenge is finding generators that are fast, trustworthy, and work without a login. These six tools deliver exactly that — instant output, no ads, no data collection.

The UUID Generator produces RFC 4122 v4 UUIDs in bulk using the Web Crypto API — genuinely random, not Math.random()-based fakes. The QR Code Generator creates scannable codes for URLs, WiFi credentials, contact information, and plain text, with PNG and SVG download options. The Barcode Generator outputs standard retail-compatible barcodes (Code 128, EAN-13, UPC-A) ready for print or digital use.

For password-specific security needs, see the full Security & Encoding Tools collection. For placeholder text specifically, also check the Developer Tools section.
