Quick answer (updated November 2026): You can make a QR code for free in under a minute. To share a web page, use the built-in QR code option in Google Chrome’s Share menu (desktop, Android and iPhone). For a branded code with your colours and logo, use the free Adobe Express QR code generator: it runs in the browser, downloads as PNG, JPEG or PDF, and Adobe says its codes don’t expire. Free generators make static codes, whose link can’t be changed after printing. Before you print, test the code with your phone camera or Google Lens. Never scan a code to pay or log in unless you trust where it came from.
QR codes are everywhere — restaurant menus, UPI payments, Wi-Fi sharing, event tickets, YouTube channel posters. Searches for “QR code generator” and “Adobe QR code generator” keep rising. This guide shows the easiest free methods, how to make codes that scan reliably, and how to avoid QR scams.
What is a QR code?
A QR (“Quick Response”) code is a square, two-dimensional barcode that a camera can read in a fraction of a second. It was developed in 1994 by Denso Wave, a Japanese company, originally to track car parts. “QR Code” is a registered trademark of Denso Wave, which chose to let anyone use the standard freely — one reason it spread so widely.
A QR code can hold a web link, plain text, contact details (vCard), Wi-Fi login, an email or SMS template, or a payment request. Most people use it for links.
Method 1: Make a QR code for a web page in Google Chrome
This is the fastest way to share a link — no website or sign-up needed.
On a computer (Windows or Mac)
- Open the page you want to share in Chrome.
- Click Share in the address bar, then choose QR code.
- Download the image, or scan it straight from the screen with your phone.
On Android
- Open the page, tap More (⋮) → Share.
- Select QR code, then download or share it.
On iPhone or iPad
- Open the page in Chrome and tap Share.
- Tap Create a QR code, then share or save it.
Method 2: Make a custom QR code with Adobe Express (free)
- Open Adobe Express’s free QR code generator in your browser (no app download needed).
- Paste your link.
- Choose a style and colours, and optionally add your logo.
- Download as PNG, JPEG or PDF. PDF is best for printing.
According to Adobe, QR codes made in Adobe Express don’t expire, and a static code’s destination cannot be changed after creation — so double-check the link first.
Method 3: Design tools such as Canva
If you are already designing a poster, flyer or YouTube banner in a design tool such as Canva, look for its built-in QR code feature so the code is placed straight into your design. The same rules apply: test before printing, and keep enough contrast.
Static vs dynamic QR codes
| Static QR code | Dynamic QR code | |
|---|---|---|
| Link stored | Directly inside the code | A short redirect link controlled by a service |
| Can you change the destination later? | No | Yes |
| Expiry | Never (works as long as the website exists) | Stops working if the service account ends |
| Scan statistics | No | Usually yes |
| Cost | Free | Usually a paid plan |
Tip: for printed material, a static code pointing to a page you control (for example your own website) gives you flexibility without a subscription — you can change that page later.
How to make a QR code that always scans
- High contrast: dark code on a light background. Light-on-dark or low-contrast colours often fail.
- Quiet zone: keep a clear margin (blank border) around the code.
- Size: bigger is safer. A common rule of thumb is at least about 2 × 2 cm for close scanning, and much larger for posters read from a distance.
- Error correction: QR codes have four levels — L (about 7% of data recoverable), M (15%), Q (25%) and H (30%). Use a higher level if you put a logo in the middle.
- Short links make simpler, easier-to-scan codes.
- Test on more than one phone, in the final printed size.
How to scan a QR code
- iPhone: open the Camera app and point it at the code; tap the link that appears.
- Android: most camera apps scan QR codes; you can also use Google Lens — in Chrome, open a new tab, tap the Lens icon, choose Search with your camera and tap the link that pops up. See our Google Lens guide.
- On a computer: Google Lens in Chrome can read a QR code in an image on the page.
QR code scams: stay safe
- Check the link preview before you open it. Misspelt domains are a red flag.
- Never enter passwords or OTPs on a page opened from a random QR code.
- UPI rule: you never need to scan a QR code or enter your PIN to receive money. Scanning is for paying.
- Look for stickers pasted over genuine codes on parking meters, shop counters and posters.
- For payment QR codes, generate them only from your own bank or UPI app — not from random generator sites.
Common mistakes
- Printing before testing the final size.
- Using a “free” generator that secretly makes a dynamic code which expires after a trial.
- Linking to a page that is not mobile-friendly.
- Too many colours or a logo that covers too much of the code.
Frequently Asked Questions
How can I make a QR code for free?
Use Chrome’s Share → QR code option for any web page, or the free Adobe Express QR code generator for a custom design with your logo.
Do free QR codes expire?
Static QR codes don’t expire — Adobe says Express codes don’t. Dynamic codes from some services stop working when a trial or subscription ends.
Which format should I download for printing?
PDF or a high-resolution PNG. Adobe Express offers PNG, JPEG and PDF.
Can I change the link after printing a QR code?
Not with a static code. Use a dynamic code, or point the static code to a page you control and update that page.
How do I scan a QR code on my phone?
Open the camera app and point it at the code, or use Google Lens on Android.
Is it safe to scan any QR code?
No. Check the link before opening it, and never enter passwords, card details or UPI PINs on a page opened from an unknown code.
Conclusion
For a quick link, Chrome’s built-in QR code is the easiest free option; for branded print material, Adobe Express gives you colours, a logo and print-ready files. Test every code before printing and treat unknown codes with caution. Creating a YouTube channel?

How we researched this
We followed Google Chrome Help and Pixel Help for the Chrome and Lens steps, Adobe’s official QR code generator pages for Adobe Express features, and Denso Wave’s official QR code site for the history and error-correction levels, checked in November 2026. We did not test paid dynamic QR services.
