A QR code for every job
Each type has its own page with a focused form, examples and tips. Pick the one that matches what you want people to do when they scan.
Why make your QR code with Scanlexa
Tested before you download
Every change is decoded in your browser. If a design won't scan, we tell you why, and the download stays locked until it's fixed.
Designs that look like your brand
Six dot styles, custom corners, gradients, your logo, a call to action and frames like ribbons, tickets and phones.
Print-ready files
PNG and JPG up to 4000px wide, sharp enough for most print. Lifetime adds SVG vector files that stay crisp at any size.
Private by design
Codes are designed on your device. Your Wi-Fi passwords, contact details and logo stay there until you save the code to your account.
How to make a QR code
Choose a type
Pick what the code should do: open a link, join Wi-Fi, start a WhatsApp chat, save a contact and more.
Enter your details
Fill in the short form. We format phone numbers, add https:// and escape special characters for you.
Design it
Choose dot style, colours, a logo, text and a frame. The preview updates as you go.
Check and download
When the badge says "Scans well", download PNG or JPG (SVG on Lifetime), and test it once with your phone.
Static or dynamic: which do you need?
Static QR codes store your content, such as a link, Wi-Fi details or a phone number, directly in the pattern. They work forever and can’t be switched off by anyone. The trade-off is that they can’t be edited after printing and don’t record scans.
Dynamic QR codes contain a short link that forwards to your content. You can change the destination after printing, schedule or pause it, and see how many people scanned, where and when. They suit menus, campaigns and anything that changes. Free dynamic codes stay active for 30 days; Lifetime ones never expire.
Frequently asked questions
Is this QR code generator free?
Yes. Design with every option for free, then create a free account to save and download: it includes 5 QR codes in total, and editing or re-downloading a saved code never uses one. An optional one-time Lifetime plan adds unlimited codes, SVG downloads and removes the small "Made with Scanlexa" line.
Do the QR codes expire?
No. The codes you make here are static: the content is stored in the pattern itself, so they work forever. Nobody, including us, can switch them off.
What's the difference between static and dynamic QR codes?
A static code stores its content directly and can never change. A dynamic code stores a short link that redirects to your content, so you can edit the destination after printing, pause it or schedule it. Dynamic codes are available with a free account for links, WhatsApp and locations.
How do I know my QR code will scan?
After every change, we decode the code exactly as it will be downloaded, at full size and at a small size, and check colour contrast and logo size. A green badge means it reads correctly; warnings explain what to improve.
What size should I print a QR code?
At least 2 cm (0.8 in) wide for things held in the hand, like cards and flyers. For posters and signs, make the code about one-tenth of the distance people will scan from. A code read from 2 metres away should be around 20 cm wide.
Should I download PNG, JPG or SVG?
PNG for websites, documents and social media; JPG if a platform only accepts JPG. For print, a 4000px PNG works for most jobs; Lifetime adds SVG, a vector file that stays sharp at any size.
Can I add my logo to a QR code?
Yes. Open the Logo section and upload a PNG, JPG, SVG or WebP. We switch error correction to the highest level and limit the logo size so the code keeps scanning.
Do you store what I put in my QR code?
Only when you save it. While you design, everything stays in your browser. When you save a code to your account, we store its content, design and logo so you can edit and re-download it, and you can delete it any time.
