QR Code Generator that proves it scans

Style your QR code, then a live scannability score — contrast, error-correction headroom, quiet zone, and a real in-browser scan test — so you catch a code that won’t scan before you download. Free, unlimited, processed entirely in your browser, and your codes never expire.

Checking scannability…contrast 21.00:1

Contrast, error-correction headroom, and quiet zone pass — running the in-browser scan test…

100% static — this code will never expire.

QR codes for every use

Each type below is the same engineering-grade tool, pre-configured for a specific payload — and every one runs the live scannability check before you export.

WiFi QR Code Generator

Share a network with one scan. SSID, password, and encryption are encoded entirely in your browser — nothing is uploaded.

vCard QR Code Generator

Put your contact details on a card people can scan — name, phone, email, and company saved straight to their phone. Encoded in your browser, with a live scannability check.

Email QR Code Generator

Make a QR code that opens a pre-filled email — recipient, subject, and body ready to send. Built client-side and scan-tested before you print.

SMS QR Code Generator

Generate a QR code that starts a text message to your number, with an optional pre-written message. Encoded locally, checked scannable before you export.

Text QR Code Generator

Turn any plain text — a note, a serial number, a short message — into a scannable QR code, entirely in your browser with a live scannability check.

What makes a QR code scannable

A QR code is read by detecting dark modules against a light background, so three things decide whether it works: enough luminance contrast (at least 3:1, ideally 4.5:1), a clear four-module quiet zone around it, and enough Reed-Solomon error-correction headroom to survive a center logo. Most generators let you break all three and only find out after you’ve printed. This one checks them as you design and runs an actual decode test on the rendered image.

Static codes that never expire

Every code here is static: the data lives in the image itself, not behind a redirect you have to keep paying for. Nothing is uploaded — generation, the logo, and the scan test all run locally — so it’s private by design and works offline.

Frequently asked questions

Will my QR code expire?

No. This generator makes static QR codes — the destination is encoded directly into the image, with no redirect or account behind it. The code is built entirely in your browser and will keep working forever. (Some 'free' generators make dynamic codes that stop working when a trial ends; that can't happen here.)

Why won't my QR code scan?

The most common causes are low contrast between the code and background, a logo that's too large for the error-correction level, an inverted (light-on-dark) color scheme, or too little quiet-zone margin. This generator checks all of these live and runs a real in-browser scan test before you download, so you catch the problem before you print.

Is it really free, and can I use the codes commercially?

Yes — unlimited codes, free, including commercial and print use. There's no signup, no watermark, and no paywall on high-resolution PNG or vector SVG exports.

Do you upload my data or logo to a server?

No. Everything — including any logo you add — is processed locally in your browser and never leaves your device. That's also why WiFi passwords and contact details encoded here stay private.

What do the error-correction levels (L, M, Q, H) mean?

They set how much of the code can be obscured and still decode: about 7% (L), 15% (M), 25% (Q), and 30% (H). If you add a center logo, use level H so the logo doesn't destroy more data than the code can recover.
