Free QR Code Generator (No Expiration)

Not the static ones this tool makes. A static QR code holds the content itself: the link, the text or the phone number is written into the pattern. No server sits in between, so there is nothing to switch off, no scan limit and no subscription.

Codes sold as "dynamic" work differently. They encode a short link on the provider's domain, which redirects to your page. That lets you change the destination later, but the code only works while the provider keeps the redirect running. If you need to change where a printed code points, encode a URL on your own domain (for example example.com/menu) and redirect that page yourself. You keep control, and the code never depends on anyone else.

Every QR code carries Reed–Solomon error correction, so it still scans when part of it is dirty, torn or covered. The QR standard (ISO/IEC 18004) defines four levels. More correction means more modules for the same content:

The version (1 to 40) is the grid size: version 1 is 21 × 21 modules and each version adds 4 per side, up to 177 × 177. The generator always picks the smallest version that fits, and the meter under the preview shows how full it is. Shorter content gives bigger modules, which scan faster and from farther away.

A logo hides modules, and the scanner has to rebuild them from error correction. Three rules keep it safe:

1. Use level H. It restores about 30% of the symbol, so the generator switches to H as soon as you add a logo.
2. Keep it under 20% of the area, leaving headroom for glare and smudges. The logo slider stops at 20%, and the tool picks a slightly larger version when needed so the logo fits.
3. Keep the corners clear. The three large squares (finder patterns) tell the scanner where the code is. The logo stays centered, away from them and from the format information beside them.

The modules behind the logo are removed rather than painted over, so the edges stay crisp. Your image is read on your device and is never uploaded.

Phone cameras turn the image into dark and light, so contrast matters far more than hue. A dark code on a light background is the safe choice; navy, dark green or a deep brand color on white all work. The generator measures the contrast as you pick colors and warns when it is low.

Light modules on a dark background are called inverted. Most phone cameras cope, but some scanner apps cannot read them, so avoid them for anything printed for the public. Keep the quiet zone, the empty border around the code: the standard asks for 4 modules. A transparent background is useful for designs, as long as what sits behind it is light and plain.

Phones act on a code by recognizing its first characters. The generator writes the formats listed in ZXing's Barcode Contents reference, which Android scanners follow and Apple supports in the iPhone camera:

For text messages, SMSTO: fills in both the number and the message on iPhone and Android; the RFC 5724 form sms:+12025550143?body=Hi is available too, but some readers drop its message. For networks, contacts and chats, use the dedicated WiFi QR code generator, vCard QR code generator and WhatsApp QR code generator.

Download SVG for print and design tools: it is vector, so it stays sharp at any size. The PNG uses a whole number of pixels per module, so its edges are crisp too.
