Will this QR code stop working?
Not on its own. The codes made here are static: your link or text is written directly into the pattern of squares. When someone scans it, their phone reads the link and goes straight there. No Mewix server sits in between, so there is nothing for us, or anyone else, to switch off. The code works for as long as the website it points to exists.
That is different from the dynamic codes many “free” generators make by default. Those encode a short link to the provider’s server, which then forwards visitors to your page. It lets you change the destination and count scans, but when the free trial ends, often after 7 to 14 days, the redirect stops and every printed copy goes dead. If you have ever seen a menu or flyer QR code land on a “subscription expired” page, that is why.
The trade-off: a static code can’t be edited after printing, and it can’t count scans. If you need a changeable destination, point the code at a page you control, such as your own website, and update that page instead.
Making a styled code that still scans
- Keep it dark on light. Phone cameras expect dark modules on a pale background. Inverted or pastel-on-pastel codes fail on many phones; the tool warns you when contrast gets low.
- Leave a quiet zone. The blank border around the code helps cameras find it. Don’t set the margin to zero if the code will sit on a busy background.
- Shorter content, simpler code. A long tracking URL makes a dense pattern with tiny squares. A short, clean link scans faster and from further away.
- Logo size is fixed for a reason. The logo takes about 22 percent of the width, which error correction H can absorb. Bigger logos are the most common reason styled codes stop scanning.
Size and file format for print
A practical rule is that a QR code should be at least a tenth as wide as the distance it will be scanned from. Scanned at arm’s length, 2 to 3 cm is enough; on a poster read from 3 metres, aim for 30 cm. Never go below about 2 cm wide.
For anything a designer or printer will handle, download SVG. It is vector, so it stays perfectly sharp at any size. PNG is fine for websites, documents and slides. The plain PDF option gives a tightly cropped code to drop into a layout.
Questions
Do you track how many people scan my code?
No, and with a static code we couldn’t. Scans go straight to your link. If you want scan counts, add UTM parameters to your URL and read them in your own website analytics.
Can I make a QR code for WiFi, a contact card or an email?
Yes. These use special formats that phones understand, so they have their own pages: WiFi QR code, vCard contact and email.
Is my link sent to Mewix when I make the code?
No. The code is drawn in your browser as you type, and nothing you enter is stored or transmitted.
