Free QR code generator

Yes. The generator is free, requires no account, and has no usage limit. The code is generated in your browser — the link or text you enter never leaves your device.

No. A QR code is just your link or text encoded as an image, so it works as long as the destination works. If you want a code whose destination you can change later without reprinting, point it at a Pubtact page and edit the page instead.

Use PNG for documents, presentations, and most print jobs — it exports at 1024×1024 pixels. Use SVG when a designer or print shop asks for a vector file that scales to any size without blurring.

Keep strong contrast between the code and its background, leave quiet space around it, and test it from another phone at the size and distance where it will actually be used — a code that scans on screen can fail on a printed card or a dim projector slide.
