QR Code Generator
A QR code generator encodes a URL, text or other data into a scannable square pattern any phone camera can read instantly. Build one for a URL, Wi-Fi network, contact card and more — with custom colors, a center logo, PNG/SVG download and printable Wi-Fi guest cards, all generated in your browser.

What actually makes a QR code reliable
A QR code is just a grid of black and white squares encoding data with built-in error correction — the same redundancy that lets a scratched or partly-covered code still scan. Most QR generator sites either wrap your content in a short link (which breaks the moment their service shuts down or the link expires) or skip logo support entirely because it needs the error correction raised deliberately, not just visually dropped on top.
This one encodes your data directly, generates the code entirely in your browser, and — if you add a logo — automatically raises the error correction level so the extra coverage in the center doesn't break scannability. Free forever, because there's no ongoing redirect infrastructure to maintain.
How to generate a QR code
-
1
Choose what to encode
Pick a type from the tabs above the form — URL, Text, Wi-Fi, Email, Phone, SMS or a Contact card.
-
2
Fill in the details
Enter the destination URL, Wi-Fi network name and password, contact info, or whatever the chosen type needs.
-
3
Customize the look
Optional: pick a color preset or set custom foreground/background colors, and add a center logo — error correction is raised automatically so it stays scannable.

Download or print your QR code
Download as PNG or SVG, copy the image to your clipboard, or print it at a real size (4–15 cm) with an optional headline — Wi-Fi codes print as a guest card with the network name and password.
For example, a Wi-Fi network encodes as:
WIFI:T:WPA;S:MyHomeNetwork;P:MyPassword123;H:false;;which any modern phone camera reads and offers to join automatically — no typing required. Press Print on the Wi-Fi tab and it becomes a ready-to-cut guest card: a "Scan to join Wi-Fi" headline, the code at the size you choose, and the network name and password written out for anyone whose phone won't scan.
Common use cases
- Linking printed menus, flyers, posters and business cards to a web page.
- Letting guests join your Wi-Fi without spelling out the password, using the printable guest card.
- Sharing your contact details at events with a contact-card code on a badge or business card.
- Opening a pre-filled email or text message for feedback, support requests or RSVPs.
- Adding a link to setup instructions, a manual or a warranty page on product packaging.
Tips and common mistakes
- Test before you print. Scan the code with at least two different phones, from the distance people will actually stand, before ordering a print run.
- Keep contrast high. Dark code on a light background scans most reliably; light-on-dark or low-contrast color pairs fail on some phone cameras.
- Size it for the distance. A common rule of thumb is about 1 cm of code width for every 10 cm of scanning distance, so a poster read from across a room needs a much bigger code than a business card.
- Point it at a URL you control. A printed code cannot be edited, so link to a page on your own site that you can redirect later if needed, and confirm where it lands with the Redirect Chain Checker. For product numbers and SKUs a scanner will read, the Barcode Generator is the better fit. The QR codes for marketing guide covers tracking scans with campaign parameters.
Frequently asked questions
No. This generates a static QR code that encodes your data directly — a URL, Wi-Fi credentials, whatever you entered — not a short link that redirects through a third-party server. It works forever, even if Frost Rank goes offline, because nothing about scanning it depends on us.
L, M, Q and H control how much of the code can be damaged or obscured and still scan — roughly 7%, 15%, 25% and 30% respectively. Higher levels add redundancy at the cost of a denser code. M is a solid default; H is used automatically when you add a logo, since covering part of the code needs that extra redundancy to stay scannable.
Yes — upload an image and it's composited into the center with a white backdrop. Error correction is automatically raised to High and the logo is capped at a safe size, so the code stays reliably scannable even with part of it covered.
The WIFI: format that phone cameras understand requires the actual network password to be embedded in the code — that's how the phone connects automatically without you typing it in. Nothing is sent to a server; the password only ever exists inside the QR image itself, generated entirely in your browser. To share it with guests, press Print on the Wi-Fi tab for a ready-to-cut card with the code plus the network name and password written out — or uncheck that option to print only the code.
Up to roughly 4,296 alphanumeric characters at the lowest error correction level, though practically much less is better — shorter content produces a simpler, faster-scanning code. This tool automatically picks the smallest QR version that fits whatever you enter.
Yes, completely free with no signup. Every QR code — including any logo you upload — is generated entirely in your browser. Nothing is ever sent to a server.
Generates real QR codes with a spec-correct encoder (the same open-source engine used across countless production QR libraries) — not a screenshot-friendly approximation — and forces High error correction whenever a logo is added, the detail most "QR with logo" tools skip.
