Free online QR code generator: URL, text, vCard — download as PNG or SVG

What to look for in a QR code generator

Most online generators add watermarks or require sign-up for PNG downloads. Browser-based generation avoids the data being sent to a third-party server.

  • No watermarks on downloaded codes.
  • No account required for basic generation.
  • Runs locally so no URL or text data is transmitted to a backend.

QR code use cases for developers

Developers generate QR codes for testing mobile deep links, embedding URLs in documentation, sharing Wi-Fi credentials, and linking print materials to web resources.

  • Test mobile app deep links by scanning QR codes during development.
  • Embed a URL QR code in slides, docs, or print without a design tool.
  • Share a staging URL quickly with a phone scan instead of typing.

Any browser-based QR generator works for basic needs. MyDevTools adds QR generation alongside API client, URL parser, and other daily developer tools in one workspace.

What file formats can I download QR codes in?
