Nookbyte QR code generator
Make a QR code for a link, Wi-Fi network, contact card and more. What you type goes straight into the code, with no redirect through anyone's server, so the code never expires. No sign-up and no watermark.
This code never expires. It holds your content directly, so scanning it does not go through any server.
What goes in the code
Colours
Error correction
Size
Scanners need a clear border. With less than 4, leave white space around the code where you place it.
SVG files have no fixed size and stay sharp when printed at any size.
Logo in the middle
Optional. The logo covers the middle of the code, so error correction switches to High to keep it readable.
How to make a QR code
- Choose what the code should hold: a link, text, Wi-Fi details, an email, a phone number, a text message or a contact card.
- Fill in the details. The preview updates as you type.
- Pick colours, error correction and size if you want to, then download a PNG or SVG.
Why these codes never stop working
A QR code is just your text written as black and white squares. Many QR code sites put a short link to their own server in the code instead, so they can count scans and let you change the destination later. The catch is that the code depends on that server. If the plan lapses or the site closes, the code stops working, even though it is already printed. The codes made here hold your content directly, so they keep working for as long as your link does.
Questions
Do these QR codes expire?
No. The code holds your link or text itself, so scanning it never goes through Nookbyte or anyone else. It keeps working for as long as the link inside it works. There is nothing to renew and no account that can lapse.
Why do some QR codes stop working?
Many QR code sites make what they call dynamic codes. The code holds a short link to the site's own server, which then forwards people to your page. When a free trial ends, a plan is not renewed or the site shuts down, that short link stops forwarding, and every printed copy of the code stops working with it. The codes made here have no middle step.
Is it free? Is there a watermark?
It is free, with no account, no watermark and no limit. You can use the codes for anything, including printed and commercial work.
Can anyone see what I put in my code?
No. The code is made by your browser on this device, and what you type is never sent to Nookbyte or anyone else. That includes Wi-Fi passwords.
How do I share my Wi-Fi with a QR code?
Choose Wi-Fi, type the network name and password exactly as they are, including capital letters, and pick the security type. Most home networks use WPA, WPA2 or WPA3, which are all the WPA option. When someone points their phone camera at the code, the phone offers to join the network.
Can I change where the code goes after I print it?
No. Because your link is inside the code, a different link needs a new code. If you expect to change it, point the code at a page you control and update that page instead.
Which error correction level should I use?
Medium suits most uses. Error correction lets a phone read the code even when part of it is dirty, scuffed or covered. Higher levels survive more damage but make the code denser, so it needs to be printed larger.
PNG or SVG?
Use PNG for websites, documents and social posts. Use SVG for printing and design tools: it is a vector file, so it stays sharp at any size.
How big should I print it?
At least 2 cm (about 0.8 inches) wide for something read up close, like a menu or a business card. For posters and signs, make the code about a tenth of the reading distance: a code read from 2 metres away should be about 20 cm wide. Keep the white margin around it.
Can I use other colours?
Yes, as long as the code stays clearly darker than its background. Scanners need strong contrast, and some camera apps cannot read a light code on a dark background. The tool warns you when the colours you pick may not scan.
