Make a QR code in seconds

A QR code is a square barcode that a phone camera can read instantly. This generator turns whatever you need — a website link, a Wi-Fi network, plain text, an email, a phone number, or an SMS — into a clean, scannable code you can download and use anywhere.

Every code is static: the content is encoded directly into the pattern, so it works forever, with no redirect, no account, and no expiry. Pick your content type, style it with your own colours, and download a PNG image or a crisp SVG vector.

How to generate a QR code

  1. Pick a content type. Choose Link, Text, Wi-Fi, Email, Phone, or SMS at the top of the generator.
  2. Enter your content. Type the link or details — the preview updates live as you type.
  3. Style it (optional). Set the foreground and background colours, the size, and the quiet-zone margin.
  4. Download. Save it as a PNG image or an SVG vector and use it anywhere.

Test before you print

Always scan your finished code with a couple of phones before printing it large. Keep a good contrast between the foreground and background (dark code on a light background scans best), and leave the quiet-zone margin in place so cameras can lock on.

常见问题

Is the QR code generator free?

Yes — completely free, with no watermark and no sign-up. Make and download as many codes as you like.

Will my QR code expire?

No. These are static codes with the content baked into the pattern, so they never expire and need no account.

Can I download a vector (SVG)?

Yes. Download as SVG for a crisp vector that scales to any size, or PNG for a ready-to-use image.

Where is my image processed?

Building or reading a QR code happens in your browser, so the file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
