How to Create a Free QR Code That Never Expires — No App, No Signup
Most people overcomplicate this. A QR code takes about 2 seconds to generate. Here's the complete guide — what types exist, which to use, and how to make one that actually works when you print it.
My cousin got married last November. She had 500 wedding invitations printed with a QR code that was supposed to link to a page with venue directions, RSVP details, and the couple's gift registry. Except she tested the QR code for the first time after the invites were already printed and in envelopes.
The link still worked. But the WiFi QR code she'd put on the reception table cards — for the venue's guest network — had a typo in the password. Printed on 40 table cards. Three hours before the ceremony.
She regenerated the QR code on her phone, reprinted the table cards at a nearby shop, and made it. But the original mistake was entirely avoidable — and this guide is partly a result of that afternoon.
Static vs Dynamic QR Codes — Know This Before Anything Else
Before you generate anything, you need to know what kind of QR code you actually want.
Static QR Codes ✅
The URL or data is baked directly into the pattern. Works forever. Cannot be edited after creation. Free to generate. This is what you want for 95% of use cases.
Best for: wedding cards, business cards, menus, WiFi codes, product labels
Dynamic QR Codes ⚠️
Points to a redirect URL that you control. You can edit the destination after printing. Tracks scan analytics. Costs money — and stops working if you cancel your subscription.
Best for: marketing campaigns where you need analytics and URL editing
Most people paying ₹999/month for a QR code tool are buying dynamic QR codes when they don't need them. If the URL you're linking to won't change, a static QR code is free and works identically.
How to Create a Free QR Code — Step by Step
Go to the QR Code Generator
Open TaskGuru's free QR Code Generator. No account needed — it opens immediately in your browser.
Select your QR code type
The tool has tabs for URL, WiFi, Text, Email, Phone, and Barcode. Pick the one you need. For most cases — linking to a website, a menu, a YouTube video, a Google Maps location — choose URL.
Enter your content
For URL: paste the full link including https://. For WiFi: enter the network name exactly as it appears (case-sensitive), the password, and the security type. For Text: type anything up to a few hundred characters.
Adjust size if needed
The default size works for screens. If you're printing, slide the size up to at least 512px. For large format printing (banners, posters), go to the maximum.
Download as PNG
Click Download. The PNG is transparent-background by default — works on any coloured background in your design. Make sure the QR code itself is dark on light, not light on dark.
ALWAYS test before printing
Scan with your phone before sending anything to print. Use both an iPhone (native camera) and Android (Google Lens or Camera) if possible. This is the step my cousin skipped.

How to Create a WiFi QR Code (The Most Useful Type)
This is the one most people come back to repeatedly. A WiFi QR code lets someone connect to your network by scanning — no typing the password, no reading it off the router, no sending it via WhatsApp.
WiFi QR Code Setup:
- Network Name (SSID): Exactly as it appears in your WiFi settings — including spaces and capital letters. Case-sensitive.
- Password: Your WiFi password. If you don't know it, check the sticker on your router or go to Settings → WiFi → network name → Show Password.
- Security Type: Almost all modern routers use WPA/WPA2. Only select WEP for very old routers (pre-2008). Select None if your network has no password.
After generating: print it and tape it somewhere visible — near the TV for guests, on the restaurant table, in the hotel room, next to your office printer. People scan, connect, done. No more "what's the WiFi?"
What People Actually Use QR Codes For
Restaurant menus
Link to a Google Drive PDF menu. Update the menu without reprinting the QR — but only if you use a dynamic QR. For static, update the linked page.
Business cards
Link to your LinkedIn, portfolio, or contact page. Much more useful than just printing a URL — people actually scan it.
Product packaging
Link to how-to videos, warranty registration, or product pages. For retail products, use a barcode (EAN-13) instead of a QR code.
Event registration
Link to a Google Form or Eventbrite page. Print on invitations, banners, and entry gates.
Google Maps location
Go to your location on Google Maps, click Share, copy the link, create a QR. Print on signboards and brochures.
Feedback forms
Link to a Google Form review request. Put on receipts and delivery packages to collect reviews without friction.
5 Things That Will Make Your QR Code Unscannable
Dark background, dark QR code
Fix: QR codes need contrast. Dark pattern on light background — always. Light on dark doesn't work reliably.
QR code too small to print
Fix: Under 1cm × 1cm is basically unscannable. On a business card: minimum 2cm × 2cm. On a flyer: 3cm minimum.
No quiet zone (white border)
Fix: Scanners need white space around all four edges — about 4 modules (pattern squares) wide. Don't cut the border in design tools.
URL redirects to a login-required page
Fix: If the linked page asks people to log in, the QR code is useless for general audiences. Test opening the URL in incognito mode first.
Typing the URL wrong in the generator
Fix: A single character typo makes the entire QR code broken. Double-check the URL in the generator before downloading, not after printing.
QR Code vs Barcode — Which Do You Need?
If you're selling products: you probably need a barcode, not a QR code. Amazon, supermarkets, and retail stores scan barcodes at checkout (EAN-13 or UPC). QR codes are for information — barcodes are for product identification in retail systems.
TaskGuru's generator makes both — select the Barcode tab for EAN-13, UPC-A, and Code 128. For Amazon FBA: use UPC or EAN-13 for product listing, Code 128 for shipping labels.
Questions People Ask About Free QR Codes
Do free QR codes expire?▼
Static QR codes — the kind generated by TaskGuru and most free tools — never expire. The data is baked directly into the pattern. As long as the URL or content the QR code points to still works, the code works. Paid 'dynamic QR codes' that track scans do expire or stop working if you cancel the subscription, but static codes don't.
What is the best free QR code generator with no signup?▼
TaskGuru's free QR code generator (taskguru.online/tools/qr-barcode-generator) generates QR codes for URLs, WiFi, text, email, and phone numbers. It also creates barcodes (EAN-13, UPC, Code128). No account, no signup, no watermark, unlimited use.
What size QR code should I use for printing?▼
For printing on business cards, use at least 300px. For flyers and posters, use 512px minimum. For large banners, use the maximum available size. QR codes also need a 'quiet zone' — a white border around the code equal to about 4 modules wide — otherwise scanners struggle at the edges.
Can I create a QR code for WiFi without an app?▼
Yes. TaskGuru's QR generator has a WiFi option. Select 'WiFi', enter your network name (SSID), password, and security type (WPA/WEP/None), and generate the code. Anyone who scans it connects to your WiFi automatically without typing the password.
How do I put a QR code on a flyer or business card?▼
Download the QR code as a PNG from TaskGuru, then open your design tool (Canva, Word, Google Docs, Adobe Express) and insert it as an image. Place it in a corner with enough white space around it. Test it with your phone before printing — always scan test before bulk printing.
