Are these QR codes free and do they expire?

Yes, completely free with no expiry. The QR code is generated in your browser and is static — it encodes the data directly, so it keeps working forever with no account, tracking or redirect service in between.

Can I make a WiFi QR code?

Yes. Choose the WiFi type, enter your network name (SSID), password and encryption (WPA/WPA2). Anyone who scans it joins the network instantly without typing the password.

How do I add my logo to the QR code?

Use the logo option to overlay an image in the centre. Keep the logo small and use a high error-correction level so the code still scans reliably.

What's the difference between PNG and SVG download?

PNG is a fixed-resolution image, ideal for screens and quick sharing. SVG is vector — it stays razor sharp at any size, so it's best for print, large signage or further editing.

Is my data uploaded anywhere?

No. The QR code is rendered entirely on your device with a local library. Nothing you type — URLs, WiFi passwords or contact details — ever leaves your browser.

Free QR Code Generator — Logo, WiFi, vCard, No Expiry

Free QR code generator

A QR (Quick Response) code is a two-dimensional barcode that stores text, a web address, contact details or WiFi credentials in a pattern of black and white squares. This generator creates them instantly in your browser for URLs, plain text, WiFi networks, vCard contacts and email — with custom colours, an optional centre logo and lossless PNG or SVG export. Everything is computed locally, so sensitive data like WiFi passwords never touches a server.

Choosing the right content type

A URL code opens a website when scanned — perfect for menus, flyers and packaging. A WiFi code lets guests join your network without sharing the password aloud. A vCard code drops your full contact card straight into someone's phone. Pick the type that matches your goal so the scanning phone knows exactly what to do.

Colours, contrast and logos

QR codes scan best with strong contrast between the foreground and background — dark on light is safest. If you add a logo or use brand colours, raise the error-correction level so the code can still be read even if part of it is obscured. Always test your final code with a couple of different phones before printing it at scale.

Print versus screen

For anything printed, download the SVG: it is a vector file that stays perfectly crisp whether it's on a business card or a billboard. For digital use — a slide, an email signature or a social post — PNG is simpler and universally supported. Keep a quiet margin of empty space around the code so scanners can lock onto it quickly.

Create static QR codes that never expire — for URLs, WiFi networks, contact cards, email, SMS and more. Customise the colours, add a logo, and download as a high-res PNG or vector SVG. Everything is generated in your browser, so your data (including WiFi passwords) stays private.

Static vs dynamic QR codes

ToolCrix generates static QR codes that encode your data directly into the pattern. They never expire and don't depend on any server. Dynamic QR codes point to a redirect URL that stops working when the subscription ends — a costly surprise when a printed flyer suddenly goes dead.

QR code types

URL — opens a website or link.
WiFi — auto-connects to a network (SSID + password).
vCard — saves a full contact card on scan.
Email / SMS / Phone — starts a message or call.
Location — opens map coordinates.

Frequently asked questions

Do ToolCrix QR codes expire? No — the ToolCrix QR code generator creates static codes that encode your data directly into the pattern, so they work forever with no server dependency.

Can I add a logo to my QR code? Yes — the ToolCrix generator embeds a centre logo and uses high error-correction so the code still scans reliably.

Is my WiFi password safe in a QR code? Yes — the ToolCrix QR generator builds the code entirely in your browser; the SSID and password are never uploaded.

Should I download PNG or SVG? From the ToolCrix generator, choose PNG for screens and most uses; choose SVG for print, since vectors scale to any size without blurring.
